Ex-S.F. Giants outfielder Mac Williamson says his career was ruined by the old placement of the bullpen mounds at Oracle Park in San Francisco ... and now, he's suing over it.

In new court docs, obtained by TMZ Sports, Williamson claims the company that financed and helped create Oracle Park knew the field design posed significant injury risks ... but did nothing about it.

And, Williamson says that all led to a catastrophic head injury that ultimately led to the end of his MLB career.

Williamson was attempting to catch a fly ball back on April 24, 2018 ... when he ran straight into the left field's bullpen mound, slipped and crashed headfirst into a wall.

Williamson stayed in the game and even went on to hit a home run ... but, in his suit, he said he began feeling groggy a short time later.

In the docs, Williamson said the next day, he was "dizzy, disoriented, and nauseous" -- and he was ultimately diagnosed with a concussion and placed on the team's injured list.

Williamson tried to come back and finish out the season ... but he claims he was still struggling with post-concussion symptoms and had shut down for the season.

30-year-old Mac went on to play in 40 games in 2019, but hit just .156 ... and was unable to latch on with an MLB team in 2020.

Now, Mac says in his suit he believes the decline in his play was all due to the injury ... and he wants the company behind Oracle Park to pay for it.

FYI -- it should be noted Williamson is NOT suing the Giants ... rather, just the company behind Oracle Park.

Williamson is asking for unspecified damages in the suit ... adding in a statement Tuesday, "My life hasn’t been the same since suffering the injury."

"The concussion ended my career and left me with life-long injuries that have also taken a significant toll on my personal life."

"I'm fortunate to have such an understanding fiancé who has been there every step of the way and helps me get through the days I suffer nausea, trouble sleeping, mood swings, and other issues. I wake up every day hoping that today is a better day and that I will get closer to how I felt before the injury."

For their part, the Giants and Oracle Park -- which ended up removing the bullpen mounds from the field after the 2019 season -- released a statement Tuesday to the San Francisco Chronicle, saying, "MLB and its clubs have a longstanding practice of addressing claims arising from player injuries through the collectively-bargained grievance procedure and the worker’s compensation system."

Sorry, Yankees ... former MLB All-Star Royce Clayton says the Dodgers will win the World Series -- telling TMZ Sports, "This is the year."

Clayton -- who we got out checking the surf in Malibu on Thursday morning -- says it pains him to make the prediction as a longtime S.F. Giant ... but he says he just sees it coming.

"I live here, I got love for them," Clayton admitted. "And, you know, if my Giants aren't in there, then I have to say I'm rooting for the home team."

Clayton says there are a few reasons he's pushing L.A. over NY and others to win the 'ship ... #1 being the addition of Mookie Betts.

"That really puts their offense in another tier," Clayton says.

Clayton added he believes the Dodgers' starting pitching is great ... and says he thinks Kenley Jansen will have a big postseason as well.

As for the team's shortstop ... Clayton tells us he LOVES Corey Seager -- adding the dude should be in line for a HUGE payday this offseason.

S.F. Giants pitcher Sam Coonrod did NOT kneel with the rest of his teammates in a showing of support for the Black Lives Matter movement Thursday ... saying his religion and his personal feelings about BLM wouldn't allow him to do it.

"I’m a Christian," the 27-year-old relief pitcher said, "so I just believe that I can’t kneel before anything besides God."

If you missed it, the MLB provided teams with a long piece of black fabric to signify unity before its Opening Day games on Thursday.

The Yankees-Nationals ceremony went off without a hitch -- players joined together in grabbing the sheet and kneeling ... and the moment was powerful.

But, later in the evening, when it came time for the Dodgers and Giants to replicate the moment ... Coonrod refused to drop to a knee.

After the game, he told reporters his religious beliefs made it impossible for him to join in ... but he also said he didn't believe in some of the things he believes BLM stands for.

"I just can’t get on board with a couple things I’ve read about Black Lives Matter, how they lean towards Marxism,” Coonrod said. “And … they said some negative things about the nuclear family. I just can’t get on board with that.”

Coonrod said he meant "no ill will" by his gesture ... and added, "I’m not mad at someone who decided to kneel. I just don’t think it’s too much to ask that I just get the same respect.”

For the team's part, manager Gabe Kapler -- who not only knelt for the BLM moment but also during the national anthem -- said he respected Coonrod's decision to opt out.

Several S.F. Giants players and coaches -- including manager Gabe Kapler -- knelt for the national anthem Monday ... and Donald Trump took aim at them afterward, calling it all a "great disrespect."

Here's the deal ... before the Giants took on the A's in an exhibition match in Oakland, Kapler and a few others decided to kneel during the pregame song to protest social injustice.

One of the players involved in the demonstration was Mike Yastrzemski, the grandson of legendary Boston Red Sox Hall of Famer Carl Yastrzemski.

The MLB praised the Giants for the move ... defending the team on social media from critics and writing, "The players and coaches are using their platforms to peacefully protest."

When one Twitter user said the team should not politicize the game ... the MLB responded, "Supporting human rights is not political."

Giants brass also weighed in on the kneeling ... celebrating the team for the moves as well, with president Farhan Zaidi saying "we're proud of our players and staff."

"We support those who knelt to peacefully protest racial injustice and those who stood to express love of country," Zaidi said. "We do not see these as mutually exclusive sentiments and believe the freedom to express both is what our country is about."

But, just hours later, President Trump chimed in on Twitter ... and he was furious to see the kneeling protests return to sporting events.

"Looking forward to live sports," Trump said, "but any time I witness a player kneeling during the National Anthem, a sign of great disrespect for our Country and our Flag, the game is over for me!"

Doesn't seem the comments are going to deter baseball players ... 'cause in San Diego on Monday night, Angels pitcher Keynan Middleton also took a knee and raised his fist during the anthem.

S.F. Giants superstar Buster Posey will NOT participate in the MLB's rebooted season ... in order to care for his newborn twin babies who are currently being treated in the NICU.

Buster and his wife have adopted identical twin girls -- they were born prematurely last week and are currently in stable condition in a Neonatal Intensive Care Unit.

It appears the outlook is good -- but as you can imagine, it's an incredibly stressful situation for any parent to endure.

Posey says the decision to opt out of the MLB season in order to be with his family is a no-brainer.

"From a baseball standpoint it was a tough decision," Posey told reporters. "From a family standpoint and feeling like I'm making a decision to protect our children, I feel like it was relatively easy."

While Posey is certainly not the first to make the call -- several others including Nationals' Ryan Zimmerman and Braves' Nick Markakis opted out several days ago -- he's definitely the biggest name so far.

Buster was expected to bat in the heart of the Giants' lineup, as usual, this season ... especially with the National League adopting designated hitter roles for the 2020 reboot.

For their part, the Giants backed their star in a statement Friday, saying, "The Giants fully support Buster's decision."

He's bigger than ever -- but Pablo Sandoval's weight gain isn't bothering his boss ... with  SF Giants Manager Gabe Kapler insisting "Kung Fu Panda" can still ball.

Here's the deal ... Giants fans were shocked when the switch-hitting infielder -- listed at 5'10", 268 lbs -- reported to camp last week looking like he let himself go during the offseason.

Sure, there's been some fat-shaming online ... but the big question -- how will the weight gain affect his performance on the field?

According to Kapler, 33-year-old Pablo is still playing like a world-class athlete!

"I think it's understandable that in today's world we focus on weight," Kapler said on Sunday according to MLB.com ... "I get it."

"In this particular case, what we've all noticed about Pablo is that the ball is jumping off his bat, and his throws have nice carry."

"Obviously, we've had concerns about whether he was going to be ready [after Tommy John surgery] and at what point he was going to be ready to play 3rd base and 1st base. He's demonstrated that he's healthy. That's the most important thing."

Did you know Barry Zito had a hell of a curveball AND an amazing voice?!?!

It's true ... the former World Series champ sang his face off all season on "The Masked Singer" -- with his voice even making Nicole Sherzinger cry before he was eliminated from the show Wednesday!!

The 42-year-old sang a rendition of Tim McGraw's "Humble And Kind" under the guise of The Rhino ... and it was so good, the Pussycat Dolls star was moved to tears.

Check out the footage ... Zito's twangy sound really had Nicole wiping away the waterworks!!

But, as it turns out, even that wasn't enough to save the former Cy Young winner from elimination ... he was booted from the show just short of making next week's finale.

Of course, it was a valiant effort from the ex-San Francisco Giant ... he finished in fourth place, and the judges praised him for being super authentic throughout the competition!!

BTW, Zito's been doing the music thing for a while -- and told us back in 2017 why he hopes to add a Grammy to his trophy case one day.

Also, don't feel too bad for Barry about the exit -- it's pretty much the only L Zito is taking in 2020 ... he just had a new baby, and his family is cute as hell!!

Former San Francisco Giants star Aubrey Huff is basking in the glory he finds from protesters taking to the streets near San Diego -- all of whom are demanding to be set free.

The World Series winner and ex-first baseman posted a rather telling video Sunday showing off a TON of demonstrators in Encinitas, CA -- just a stone's throw away from central SD. They were out there with a ton of signs, all with the same goal ... reopening the area -- specifically, their hiking trails, beaches and whatever else is closed out there.

Aubrey was digging the vibes. He captioned his vid, "This is what freedom looks like. Current situation in Encinitas, CA. But a friendly reminder to my fellow #coronavirus protesters. If you’re gonna demand the beaches opening back up don’t wear a mask."

Other videos captured a bunch of what appeared to be Trump supporters waving the American flag and donning red MAGA hats. Some reports even say people were chanting, "Let us surf!" near the shore. In any case, these San Diego County residents are out in force.

It's just the latest protest staged across the country -- there were several that took place on Saturday alone ... not to mention the ones that swept through the Mid-West earlier in the week ... including a couple in Huntington Beach in Orange County, not far from L.A.

The S.F. Giants will NOT allow Aubrey Huff to be a part of their 2010 World Series reunion later this year ... and they say it's all 'cause of their ex-star's actions on Twitter.

"Earlier this month, we reached out to Aubrey Huff to let him know that he will not be included in the upcoming 2010 World Series Championship reunion," the Giants said in a statement Monday.

"Aubrey has made multiple comments on social media that are unacceptable and run counter to the values of our organization."

Huff has used his Twitter page to send off controversial tweets almost weekly throughout the past couple years ... but it was a series of comments he made about the Giants' hiring of a female bench coach last month that really landed him in hot water.

Just hours after SF made Alyssa Nakken the first full-time female coach in MLB history ... Huff ripped the move, writing, "Couldn’t imagine taking baseball instruction from an ex-female softball player."

He later added, "I got in trouble for wearing a thong in my own clubhouse when female reporters were present ... Can’t imagine how it will play out with a full-time female coach running around. This has #metoo & #BelieveAllWomen written all over it."

Huff -- who also made headlines last year for his pro-Donald Trump tweets about teaching his kids to use guns just in case Bernie Sanders becomes the next president -- was NOT happy about the Giants' decision to bar him from the celebration.

"Quite frankly, shocked," Huff told The Athletic on Monday. "Disappointed. If it wasn’t for me, they wouldn’t be having a reunion ... But if they want to stick with their politically correct, progressive bullsh*t, that’s fine."

Huff went on to blast team CEO Larry Baer -- who was caught on video last year in a fight with his wife -- for the move, writing, "I find this whole thing very hypocritical coming from a man who has had his share of real controversy for pushing his wife."

He added, "And while I'm disappointed the Giants are so opposed to President Trump, and our constitutional rights that they'd uninvite me to my team's reunion, it shows me that now more than ever we have to stand up for our first 1st amendment rights."

Huff was a superstar for the Giants in 2010, hitting .290 with 26 home runs and 86 RBIs. He finished seventh in the MVP vote that season.

The Giants, though, say there's no chance they let him be a part of their planned reunion on Aug. 16, saying, "While we appreciate the many contributions that Aubrey made to the 2010 championship season, we stand by our decision."

"Couldn’t imagine taking baseball instruction from an ex-female softball player."

Well, this is a horrible take ... courtesy of former San Francisco Giants star Aubrey Huff.

The ex-Silver Slugger winner -- and current internet troll -- just went off on his former team in spectacularly sexist fashion ... blasting the Giants for becoming the first MLB squad ever to hire a full-time female coach.

"I got in trouble for wearing a thong in my own clubhouse when female reporters were present," Huff said. "Can’t imagine how it will play out with a full-time female coach running around. This has #metoo & #BelieveAllWomen written all over it."

Yeah, yikes.

Of course, the Giants couldn't possibly have a more opposite take than Huff ... they said Alyssa Nakken will change their clubhouse in a way not many people EVER could.

In fact, Giants manager Gabe Kapler said of the ex-Sacramento State softball superstar that he's "delighted" to have her be around the team in 2020.

But, Huff -- who won two World Series titles with SF in 2010 and 2012 -- continued with the sexism anyway ... telling former teammates Brandon Crawford, Brandon Belt and Buster Posey to "Have fun with that."

Forget the Eiffel Tower ... S.F. Giants rookie Mauricio Dubon turned to Paris' version of Mickey Mouse to propose to his smokin' hot GF -- and it worked, 'cause she told him yes!!

Dubon -- one of the top minor league prospects in the MLB heading into this season -- was on an offseason vacay with his girlfriend, Nancy Herrera, when he decided to get down on one knee at Disneyland Paris.

Right in front of a pond and Mickey shrubbery ... the 25-year-old shortstop asked Nancy to marry him -- and she said of course!!

The video is adorable ... the two look SUPER happy -- and Nancy wrote on social media afterward, "I LOVE YOU and what a great blessing to be able to share the rest of my days with my best friend and the love of my life"

Mauricio ain't a star yet -- he's still an up-and-comer in the big leagues ... but he sure knows how to pick out a ring -- check out the INSANE rock!!!

Don't worry, Dubon can afford it ... he played on a 1-year, $555,000 deal this season -- and he could be in line for a fat contract if he lives up to his potential in 2020.

Congrats!!!

Surreal scene at Fenway Park on Wednesday ... Red Sox legend Carl Yastrzemski threw out the first pitch of the night to his grandson -- Giants outfielder Mike Yastrzemksi!!!

The odds of seeing this moment are wild ... to have Mike be called up from the minors this year AND to have S.F.'s schedule put the team in Boston this season are incredible coincidences.

But, the two squads took advantage of the opportunity -- allowing 80-year-old Carl to hurl the first pitch to 29-year-old Mike before the Giants played the Sox in the 2nd game of their 3-game series.

The video of the interaction is spine-tingling ... Mike has a huge smile on his face the whole time, and Carl -- one of Boston's all-time greatest athletes -- is clearly loving the moment too.

The Yastzemski's shared an embrace in the middle of the diamond after throw ... and when the game ended, Mike called it all "special."

"Honestly, I was thinking about the last time we had played catch," Mike said. "I remembered a time probably during Thanksgiving when I must have been 7 or 8 at his house."

"Being able to relive that and to go through that again on this type of scale and to have such a warm welcome from everyone was really awesome."

Mike killed it in his debut in the same batter's box Carl used to play in ... so far in the series, he's 3-for-11 with a home run, 4 runs scored and 2 RBIs. His team's gotten both wins too!

Alex Rodriguez had HALF A MILLION DOLLARS worth of stuff stolen from his rental car while he was in San Francisco broadcasting a Giants-Phillies game ... TMZ Sports has confirmed.

Law enforcement sources tell us the MLB legend -- who was in town for his ESPN gig as a baseball color commentator -- had his rented SUV broken into just a few blocks from Oracle Park on Sunday.

We're told the burglary happened around 10 PM ... and the thieves made off with $500,000 worth of electronics and jewelry.

Rodriguez had been at the stadium nearly the entire day ... he and his ESPN crew called the Giants' 9-6 win over Philadelphia on "Sunday Night Baseball."

Law enforcement sources tell us they've made the case a high priority ... with investigators working overnight to collect evidence.

We've reached out to Rodriguez for comment ... but so far, no word back yet.

Great American Ballpark in Cincinnati turned into a nightmare scene straight out of "My Girl" on Monday ... when a swarm of bees invaded the stadium -- forcing officials to delay the start of the game.

The Reds were gearing up to take on the San Francisco Giants when the bees came ... you can see in photos and video there are THOUSANDS (maybe millions?) of the flying insects on the field.

In one shot captured by NBC Sports Bay Area, you can see just how close the bees came to the Giants dugout. Scary stuff.

At one point, Reds outfielder Derek Dietrich grabbed some beekeeping stuff and charged out on the field -- jokingly trying to help officials get rid of the bees.

No word if it actually helped ... or not. Also, unclear if anyone was stung.

The good news ... officials say the swarm eventually moved on and the game is now underway.

Major League Baseball has suspended San Francisco Giants CEO Larry Baer -- without pay -- until July 1, 2019 for stemming from a March 1 incident with his wife, TMZ Sports has learned.

He must also undergo counseling.

MLB commish Rob Manfred says the unpaid suspension will be backdated to March 4, 2019 -- the day Baer took a leave of absence from the team.

"During the period of his suspension, Baer shall have no involvement in the operations of the Giants," Manfred says.

"The Club shall be operated by an interim control person appointed by the ownership group in consultation with the Commissioner. Baer will be required to undergo an evaluation by an expert to determine an appropriate treatment and counseling plan."

Manfred says, "At my direction, the Department of Investigations conducted an investigation into the March 1, 2019 video-recorded incident involving Larry Baer. I also personally met with Mr. Baer."

"Based on my review of the results of the investigation, I have concluded that Mr. Baer’s conduct was unacceptable under MLB policies and warrants discipline."

"In determining the appropriate level of discipline, I find that Mr. Baer should be held to a higher standard because as a leader he is expected to be a role model for others in his organization and community."

"Based on my conversation with Mr. Baer, it is clear that he regrets what transpired and takes responsibility for his conduct."

TMZ Sports posted video showing Baer in a physical altercation with his wife in a public park -- ultimately knocking her to the ground in a struggle to pry a phone out of her hands. You can hear her screaming, "Oh my god. Help!"

Baer's wife has publicly supported Larry after the incident -- chalking the whole thing up to an ordinary marital spat.

Larry has also issued a statement on the suspension ... saying, "I respect and accept the Commissioner's decision, and I respect and accept the Commissioner's decision, and appreciate the fair and thorough process undertaken by MLB and the Giants."

"I made a serious mistake that I sincerely regret and I am truly sorry for my actions. My unacceptable behavior fell well short of what must be demanded of every person, particularly someone in my position and role in the community."
