He might not be great in October, but Alex Rodriguez is CRUSHING IT in May ... 'cause the baseball star just sold his Miami Beach mansion for a $15 MILLION profit, TMZ has learned.

We know ... A-Rod has accepted a $30 million offer for his 19,861-square-foot Miami Beach estate ... the same property he purchased in 2010 for $7.4 mil.

After he bought the place, the NY Yankees star sunk an additional $7.6 million into building his dream home -- meaning his total investment was $15 mil.

The home is unreal -- an oceanfront palace with 9 bedrooms, 11 full bathrooms (plus 2 half bathrooms), a 4-car garage, state of the art security system with 16 cameras and a Zen garden.

Plus, it's on the same street as Matt Damon!

Rodriguez quietly put the place on the market in August 2012 and was asking for $38 mil -- but ultimately, he decided to settle for a measly $30,000,000. Bummer ...

So who bought the joint? Unclear at this point ... but sources tell us the buyer is a celebrity who lives in Palm Beach.

Stay tuned ...

Jose Canseco is under investigation in Las Vegas after a woman filed a report accusing the former MLB star of sexual assault ...  but Jose says it's all BS, TMZ has learned.

Law enforcement tells us ... the 48-year-old retired baseball player has been named as a suspect in a police report filed with the Las Vegas Metro Police Department.

We're told ... the person who filed the report says the incident went down on May 10.

Canseco went to his Twitter page moments ago and said, "[The accuser] told police that I druged [sic] her and then raped her. hmmmmm. lets find out what really happened."

The accuser appears to be a fitness instructor who lives in Vegas.

Story developing ...

The only thing Denver Nuggets star JaVale McGee likes more than a goofy outfit ... IS A GREAT RIDDLE ... and last night, he challenged TMZ to a quality brainteaser right on the street!

Here's the deal ... McGee was leaving Crustacean in L.A. last night when one of our photogs hit up the 7-footer with a bunch of random, weird questions ... like, "How much would your $44 million contract weigh in gold bars?"

McGee didn't like the fact he didn't know the answer ... so he totally turned the tables -- and asked a riddle of his own!

The whole exchange is pretty funny ... our photog's a goofball, JaVale's a goofball -- turned out to be a pretty hilarious encounter.

Noah Wyle has a killer sports memorabilia collection -- KILLER -- and last night, the "Falling Skies" actor revealed his most prized possession ... and it has to do with Jackie Robinson.

Wyle was leaving Madeo last night with his girlfriend Sara Wells when we started talking baseball ... since the former "ER" star is known for being an avid baseball card collector.

But when it came to the crown jewel of Wyle's collection -- it wasn't a card ... but it has something to do with the 1952 Brooklyn Dodgers, one of the most important squads in the history of baseball.

And why, you ask? Just take a look at the roster -- Jackie Robinson, Pee Wee Reese, Gil Hodges, Duke Snider and Joe Black, the first African American pitcher to win a World Series game.

Pretty sweet, Wyle.

Former WWE diva Tamara Sytch is FREE from a Connecticut prison after a four-month stint for REPEATEDLY violating her ex-boyfriend’s restraining order ... and her stay included a cancer diagnosis and hysterectomy.

Tammy, who managed and wrestled under the name "Sunny" back in the day, was arrested 6 TIMES in just over 4 months beginning last September -- including 3 times in 3 days -- all relating to the same dude. Charges included disorderly conduct, assault, 3rd degree burglary ... and violating the BF's TRO at just about every step.

She was most recently popped in January ... and sentenced to 114 days in prison ... which she's now served in full.


Tammy told us she contracted HPV before going into prison ... and found out while doing time that it had developed into cervical cancer. She says she underwent a hysterectomy at an area hospital a couple of weeks ago ... and is now cancer-free.

She says she also used her time to write an autobiography ... and plans to make a fresh start in New Mexico.

Tammy will be on conditional discharge for the next two years … provided she doesn’t show up where she’s not welcome.

One day after Lindsey Vonn was spotted playing mom by dropping off his kids with Elin Nordegren at school alone, Tiger Woods joined in on the child-rearing fun.

Looking like one big happy family, Tiger and Lindsey -- who have been dating for around 5 to 6 months -- made the early morning trek to drop off his adorable children at their Palm Beach school on Tuesday.

The athletic lovebirds are really committed ... to getting those kids to class on time.

Atlanta Hawks player Dahntay Jones says he feels REALLLY bad about injuring Kobe Bryant's ankle right before the NBA playoffs ... but he's adamant, he didn't do it on purpose!

Jones was at LAX yesterday when he told TMZ ... even though it's only been 2 months since the controversial play, he doesn't hold a grudge against people like Ice Cube -- who called him a dirty cheater days after the play. 

In case you forgot, Lakers fans were calling for Dahntay's head after Kobe landed on DJ's ankle during a jump shot on March 13 -- with people saying Dahntay put his foot in Kobe's jump zone with the intention of injuring the NBA star.

"I apologize once again," DJ told us ... "I wish you a speedy recovery, Kobe."

Forgive him yet?

The home of Baltimore Ravens running back Ray Rice was struck by a burglar this weekend ... and the scumbag made off with two guns and $2,000 in cash ... this according to police.

Cops say Rice wasn't home at the time of the burglary -- which went down between 8:30 am Friday and 12:50 am Saturday -- but a friend was staying at Rice's Maryland home and reported the incident to police.

The good news ... cops say there is surveillance video of the crook entering through a rear window and ransacking the home.

Rice released a statement to USA Today saying, "My family and I are fine, which is the most important thing. This is an unfortunate incident that I am dealing with through the proper channels.''

Exactly two years ago, "Macho Man" Randy Savage died in a car crash in Florida -- and today, the wrestler's family is honoring his memory by eating at a restaurant dear to his heart ... the Olive Garden.

Randy's brother Lanny Poffo tells TMZ he and his 86-year-old mother Judy decided to celebrate Randy's incredible life with a special lunch ... and they picked Olive Garden in Tampa, FL because it was always the go-to spot for family functions.

Lanny says ... the family shared so many happy memories at the O.G. -- so today, they wanted to focus on his life and the good times ... and not his death.

As for Randy's widow, Lanny tells us ... she's still having an especially tough time getting through the day, considering she was a passenger in Randy's car when he suffered a heart attack and veered into a tree back in 2011. He was 58.

"I have to be strong for my family now," Lanny says ... "I'm just glad to have had him as a brother and wanna celebrate his life as much as I can instead of continuing to mourn."

Lindsey Vonn might be in it with Tiger Woods for the long haul ... because she was spotted this morning taking his kids to school ... with no sign of Tiger.

The two awkwardly announced their relationship via Facebook back in March, saying they have "been friends for some time, but over the last few months we have become very close and are now dating."

That means their relationship is somewhere around the 5 or 6 month mark.

So, we gotta ask ...

With a ratty blonde mohawk weave, enough drag makeup to make any 4 AM Hollywood Blvd. streetwalker jealous and some sort of loud Hawaiian print blazer, Dennis Rodman hit up "The All-Star Celebrity Apprentice" finale in New York City on Sunday ...  looking like the bastard love child of Rupaul and Tina Turner in "Mad Max Beyond Thunderdome."

The 52-year-old former NBA star turned clown finally managed to do something worse than vacation with North Korean dictator Kim Jong Un.

He is the United States embarrassador.
