San Francisco Giants first base coach Antoan Richardson claims he was ejected on Tuesday night for confronting a Padres coach over what he says was a comment that "reeked" of racism.

Richardson, who's Black, made the allegations following SF's win over San Diego ... saying it all started in the third inning, when Padres coach Mike Shildt, who's white, picked a fight with him while he was in the Giants' dugout.

Richardson told media members that Shildt was looking for someone in the Giants' dugout ... and when he asked who he wanted, Shildt got snippy.

"At this time, he's walking toward our dugout," Richardson said of Shildt. "And then he says, 'Hey. I was looking for Alex Wood.'"

Richardson says the exchange of words got so heated, SF manager Gabe Kapler came over to defuse the situation. Then, that's when he claims Shildt unleashed a comment that he believed dripped with "undertones of racism."

"He yelled, 'You need to control that motherf***er,'" Richardson said.

Richardson said he was so taken aback by the comment, he stepped toward the top of the dugout to confront Shildt -- and was ultimately ejected for the action.

"His words were disproportionality unwarranted," Richardson said of Shildt. "And reeked of undertones of racism. When he referred to me as 'that motherf***er,' as if I am to be controlled or I'm a piece of property or enslaved."

Richardson then ripped MLB umpire Greg Gibson for ejecting him ... saying, "Me being tossed by that umpire empowered this coach to continue to have conversations like that with people like me. And that's really unfortunate that that's what happened tonight."

Shildt -- who managed the St. Louis Cardinals last year -- and Padres manager Bob Melvin did not comment on the incident following the game.

While it was all a disturbing situation for Richardson, his ejection did lead to some MLB history -- Alyssa Nakken took over his coaching duties on the field ... and became the first woman in MLB history to ever do so.

"I'm really excited that Alyssa (Nakken) got her opportunity to make her Major League debut and I'm very proud of her," Richardson said. "I think she did a really wonderful job and we got a win, so that's the most important thing."

Kapler, meanwhile, addressed the incident following the game and said he believes Richardson's side of the story to be true.

"I trust Antoan's judgment 100 percent. I trust Antoan's judgment on the matter and I know that Antoan was not out of control at all and that anything that was said to insinuate that he was is totally inappropriate."

"He didn't instigate any part of this."

Barry Bonds' historic 500th home run ball -- launched into McCovey Cove during the 2001 MLB season -- is on the auction block ... and is expected to bring in around a quarter-million bucks!

Of course, the 500 Home Run club is one of the most prestigious groups in all of Major League Baseball ... consisting of just 28 legendary sluggers like Babe Ruth, Willie Mays, Hank Aaron and the home run king himself, Bonds.

The ball Barry crushed off Dodgers pitcher Terry Adams on April 17, 2001 is now available for bidding at SCP Auctions (the same people who sold Ruth's 500th home run bat for $1 million!)

FYI, Bonds '01 season is arguably the greatest in the history of the sport. Barry slugged 73 home runs, had 137 RBI (even though he was walked 177 times, many intentional), had a batting average of .328, an on-base percentage of .515, and an astronomically high OPS (On-base + Slugging %) of 1.379.

Ridiculous, absurd ... there are no words for Bonds' domination.

Barry ultimately hit 762 home runs ... making him the all-time leader.

Regardless of the fact BB launched hundreds of more long balls after that night in April ... his 500th shot is still monumental because the mark represents admittance into an ultra-exclusive club.

If you wanna own the ball -- which is being consigned by the actual fan who scooped the ball out of the water in the San Francisco Bay -- you only have a few days left to bid.

BTW, speaking of exclusive clubs ... SCP is also auctioning off Affirmed's Triple Crown trophy from 1978 -- when the thoroughbred won the Kentucky Derby, The Preakness, and the Belmont Stakes.

Not a horse racing fan -- but also very wealthy? The Holy Grail of baseball cards, the Honus Wagner T206 card is also on the block ... and is expected to bring in OVER $2 million.

All of the auctions close on Saturday.

S.F. fans might be hurting right now, but there's something to look forward to for next season ... 'cause UFC star Nate Diaz says he wants to throw out the first pitch at a Giants game -- and put Conor McGregor's toss to shame!!

Of course, Diaz's nemesis had one of the worst ceremonial first pitches EVER back in September ... chucking the ball wide right of the plate, but claiming it was actually great.

So, when we spoke with the 36-year-old at the Deontay Wilder vs. Tyson Fury fight last weekend -- before the Giants' heartbreaking exit from the postseason -- we asked if he was gonna try to get the same honor at Oracle Park.

Diaz disses McGregor with his response -- saying if he does get the opportunity, he's gonna hit the target!!

When we asked if his pitch will be better than Conor's, Diaz made it clear he'd look like Logan Webb out there on the mound.

An MLB game was paused for several moments Monday night ... after a fan ran onto the field and pretended to throw pitches on the mound.

The bizarre scene all went down during the Mets vs. Giants game at Oracle Park in San Francisco ... when a guy in a Padres jersey bolted from his seat and jumped onto the field.

You can see in footage from the ballpark ... the guy ran around the infield grass for several seconds before he hopped onto the bump and went through an entire pre-pitch routine.

He toed the rubber, pretended to shake off Buster Posey's signs ... and then made a move toward second base.

Three security guards, though, eventually corralled the dude and tackled him to the ground ... and then escorted him off the field through the dugout.

Kris Bryant cried and needed multiple hugs after learning he was being traded out of Chicago ... and video of his emotional departure from the Windy City will hit ya right in the feels.

The Cubs star was dealt to the S.F. Giants just minutes before Friday's MLB trade deadline ... and when he learned of the news via a phone call in the dugout, it ain't hard to see it hurt like hell.

Bryant dapped up and hugged a Cubs staffer, and then began to tear up. And, when the waterworks began to flow heavily, he needed a second hug before leaving the dugout.

Of course, Chicago is all Bryant has known ... he was picked by the Cubbies in the first round of the 2013 MLB draft, and has been a star just about every day since.

Bryant won the NL Rookie of the Year award in 2015, NL MVP honors in 2016, and he helped Chicago win a World Series title in '16 as well.

We don't know if we should crown this guy Dad of the Year, or Gutsiest Dad of the Year ... because he could easily fall into both for this incredible feat with his kid and a baseball.

Check out this insane clip of what seems to be a relatively new father holding his child at the Arizona Diamondbacks game Sunday, where they were in Phoenix facing the visiting SF Giants. Of course, when you go to a live game ... ya gotta look out for those foul balls.

They can come at you fast when coming off a player's bat at the plate ... and that's exactly what happened here for this fella. His instinct was ... catch the damn thing, barehand!

Watch for yourself -- he literally releases the baby that he's holding in his left hand/arm to reach up and snag the ball midair (which he successfully does) ... and an instant later, he swings his arm back down to catch the falling kid (again, he pulls it off somehow).

BTW, we forgot to mention ... Papa Bear here was also carrying a beer in his free hand -- so it's literally like a circus stunt. He spilled a little while making the amazing catch(es), but the suds stayed mostly intact. As freaked as people were, they were equally impressed.

The SF Giants' classic black and orange will be getting a touch of rainbow this weekend ... the team says it will recognize Pride Month by wearing Pride colors on its uniforms.

Giants officials say they'll add a "Pride Patch" on the sleeve of their jersey Saturday against the Chicago Cubs ... and they'll debut a custom cap for the game as well.

"We are extremely proud to stand with the LGBTQ+ community," team prez and CEO Larry Baer said, "as we kick off one of the best annual celebrations in San Francisco by paying honor to the countless achievements and contributions of all those who identify as LGBTQ+ and are allies of the LGBTQ+ community."

Pride Month began Tuesday as the calendar officially rolled over into June ... and the Giants are going all in to make sure they honor the moment.

In addition to the uniform changes ... SF officials also say they'll adorn their scoreboard with Pride colors and wrap Willie Mays Plaza palm trees with the hues as well.

"Very proud that the San Francisco Giants are taking this step," Giants manager Gabe Kapler said Tuesday. "Very proud to be part of it."

Barack Obama had nothing but beautiful things to say about Willie Mays on the MLB legend's birthday ... even saying the ex-SF Giant helped pave the way for his presidency.

Obama posted the cool happy birthday note to the former slugger on his Twitter page Thursday ... saying, "Happy 90th birthday to Willie Mays!"

"If it wasn't for folks like Willie and Jackie Robinson, I might never have made it to the White House."

Obama continued, "The spirit he played with and the way he carried himself changed the game and people’s attitudes. I’m glad he’s still going strong."

Obama and Mays have had a friendship that dates back years ... Mays famously rode on Air Force 1 with Obama in 2009 when the two were on the way to the '09 MLB All-Star Game in St. Louis.

Obama later went on to joke about that trip ... saying, "Very rarely when I'm on Air Force 1 am I the second-most important guy on there. Everybody was just passing me by, 'Can I get you something, Mr. Mays?"

In 2015, Obama awarded the Presidential Medal of Freedom to Mays as well.

Mays is to this day still one of the best baseball players that's ever lived ... he was a 2-time MVP, 24-time All-Star and a 12-time Gold Glove winner.

Scary moment on the MLB diamond Tuesday night ... umpire Kerwin Danley was hit in the face by a foul ball -- and appeared to be knocked out cold behind home plate.

The tense moments all went down in the 6th inning of the Giants vs. Rockies game in San Francisco ... when Sam Hilliard foul-tipped a pitch right into Danley's facemask.

You can see in footage from the broadcast of the game, Danley immediately fell backward and laid motionless for several seconds.

Really scary moment.

Trainers rushed to tend to the 59-year-old ... and, fortunately, he was able to get up minutes later and leave the field under his own power.

The Giants said after the game that Danley was "doing well" ... though he was experiencing a "slight headache."

This is not the first time Danley -- who's had a history of concussions -- has had a scare behind home plate ... back in 2008, he was hit in the jaw by a fastball, and a year later, he was hit in the head by a broken bat.

STOP WHAT YOU'RE DOING AND LOOK AT THIS ADORABLE BUNNY!!!

A pair of San Francisco Giants fans hit up Oracle Park to watch their boys take on the Miami Marlins on Thursday ... and forget the peanuts and crackerjacks, they brought their cute ass therapy rabbit along to enjoy the fun!!

The 4 1/2-month-old bunny named Alex belongs to owners Kei Kato and her fiancé, Josh Row ... who bought the Flemish giant after Kato's brewery restaurant closed during the COVID-19 pandemic.

Alex helps with Kato's anxiety and stress ... and brings joy to the couple's life during the tough times.

The furry friend has been living it up since he joined the family -- from NASCAR races to tubing and kayaking ... and even helped hand out Easter eggs to kids!!

The fun continued when Kato and Row brought Alex to his first baseball game ... and it was a monumental moment -- it's believed he's the VERY FIRST bunny to attend a ballgame at Oracle Park, according to the team.

Alex -- who was wearing a Giants-colored bowtie -- quickly became a fan favorite ... and the Marlins even tried to convert him to their side with some free merch, while SF invited him back as their good luck charm.

Giants CEO Larry Baer also spoke about their new fan ... saying, "Love this therapy bunny," Baer said. "We could all use a therapy bunny right about now!"

So, what's next for the lovable trio?? They're hoping to hit up a Warriors game ... and Golden State has already welcomed Alex with open arms.

Mike Yastrzemski says he will NOT kneel for the national anthem this season after taking a knee for the song last year ... the MLB star told reporters Thursday he feels he's already made his statement.

The S.F. Giants outfielder, who's the grandson of Red Sox legend Carl Yastrzemski, began demonstrating during the Star Spangled Banner after the MLB came back from its COVID delay last summer.

At the time, the 30-year-old wrote a powerful message on social media explaining his decision to kneel ... saying, in part, "By kneeling last night, I wanted to hold myself, and hopefully others, accountable that something needs to change."

He continued, "and I am willing to be part of the change because we all deserve the freedom that our veterans and active members have sacrificed their lives for."

Yaz, though, says the kneeling will end when the Giants kick off their season Thursday night.

According to The Athletic's Andrew Baggarly, Yaz explained to reporters, "he knelt last year to spark conversation and awareness and let people know where he stands on racial justice and feels he's made that statement."

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.
