New York Yankees

Former L.A. Dodgers and N.Y. Yankees second baseman Steve Sax has a bone to pick with the company that made his bobbleheads -- he says it screwed him out of some cash for his John Hancock.

Sax claims he made a deal with sports gear company Forever Collectibles for $10,000 -- allowing them to produce a bunch of bobbleheads in his likeness and sell them at an event in June ... and he'd sign about 504 of the 'heads.

According to the legal docs that all worked out fine, but Sax says FC also agreed to pay him another $5,000 to be at the event and sign extra autographs and inscriptions ... which he claims he did.

The problem, according to the suit, is the company never coughed up the additional dough. Now he's going after them for the $5k ... plus interest.

David Ortiz says he's got a great idea which teams are gonna end up in the World Series ... and in true Red Sox fashion, he's showing no love for the Bronx Bombers.

TMZ Sports spoke with the Boston legend and current FS1 analyst at Mastro's in Beverly Hills about his fall classic picks ... and Big Papi has no faith in the Yanks to bounce back from being down 0-2.

NY Yankees legend Jorge Posada has teamed up with some HUGE stars to rescue injured and sick people in hurricane ravaged Puerto Rico ... and he's not done yet.

TMZ Sports spoke with Jorge and his wife Laura -- who just got back from another humanitarian mission to P.R. -- where they brought food, supplies, water and more to people in need.

But they're not going at it alone -- the Posadas joined forces with superstars like Gloria Estefan, Ray Allen, Luis Fonsi (the "Despacito" guy!), Ricky Martin, Carlos Arroyo, Bernie Williams, Ivan Rodriguez and more.

The gang has flown into P.R. together to distribute aid to residents. They've also raised more than $300,000 in their YouCaring page.

Laura Posada says she and Jorge have personally flown to P.R. three times already -- "We’ve brought back in each plane 50 people. And this Friday, we’re going to do that again."

"We’re gonna send a plane with 10,000 pounds and we’re gonna to bring back 15 patients. And these are patients that are critically in need of medical treatment."

Salute.

Tribe fans might wanna look away ... 'cause this one's gonna sting.

The New York Yankees went booze bonkers after eliminating the Cleveland Indians in Game 5 of the ALDS Wednesday night ... celebrating with tons of bubbly and brew.

Didi Gregorious -- who single-handedly crushed Cleveland's dreams with 2 homers in the game -- picked up right where he left off the Wild Card victory party ... but on a budget this time around.

ICYMI -- Didi and Aaron Judge brought out the huge $300-a-bottle Ace of Spades champagne after beating the Twins last week. This time ... they went with $20 bottles of Mumm Napa Cuvee M.

Hey, whatever gets the job done, right?

Aaron Judge ain't a rookie when it comes to celebrating his first postseason win ... 'cause the star slugger brought out the big (gold) guns for the Yankees' victory over the Twins Tuesday night.

Judge and his teammate Didi Gregorious went all-out for the team's champagne celebration after winning their wild-card game 8-4 ... poppin' massive bottles of Ace of Spades.

FYI -- a regular bottle of Ace of Spades will set you back around $300 ... so it's an expensive booze shower.

But don't worry, the Yanks have a day off before taking on the Cleveland Indians in the ALDS on Thursday.

Former New York Yankee Pat Kelly says he and his girlfriend getting booked for assault was just a "misunderstanding" ... and "everything's good" now that he's outta the slammer.

TMZ Sports broke the story ... Kelly and his GF, Marina Cernova, were arrested at the London Hotel in NYC on Sunday after Marina called cops to report Pat had beaten her.

Both Pat and Marina were jailed for misdemeanor assault ... 'cause police say Marina also punched Pat in the face.

But when we got Kelly outside Manhattan Criminal Court ... he told us he was A-OK -- though he did seem kinda annoyed that our guy wouldn't give up his sources.

5:40 PM PT -- Pat and Marina were both released from jail and were issued temporary restraining orders to stay away from each other.

5:20 PM PT -- Kelly's attorney Alex Spiro tells us, "Pat denies all wrongdoing and will answer the charges in court."

1:55 PM PT -- Law enforcement sources tell us Pat told cops he was sleeping in his hotel room early Sunday morning when his girlfriend entered with a key he'd given her. That's when they got in the argument, at which point he says she punched him in the face, causing him to react by grabbing her by the arm and pushing her.

Former New York Yankee Pat Kelly and his girlfriend were busted in NYC over the weekend for assault ... TMZ has learned.

Law enforcement sources tell us Pat was arrested Sunday at the London Hotel in midtown along with his girlfriend, Marina Cernova.

We're told they engaged in a verbal dispute, and she punched him in the face. She told cops he grabbed her right arm and pushed her, which she says caused pain and bruising. She called cops around 2:40 AM to report Pat had beaten her.

Cops arrested and booked both of them for misdemeanor assault ... we're told they're still in jail.

MLB commish Rob Manfred just dropped the hammer on the Red Sox ... fining the club an "undisclosed amount" of money for stealing signs using banned electronic devices.

Baseball investigators determined the BoSox violated MLB rules by "sending electronic communications from their video replay room to an athletic trainer in the dugout."

While Manfred did not specify the amount of the fine ... he did say the cash would go towards Hurricane Irma relief in Florida.

The Sox weren't the only ones lighter in the wallet ... the commish says he determined the Yankees broke a rule prior to the '17 season, so he fined them also.

The amount ... "lesser undisclosed amount" -- also going to storm relief.

We spoke with Manfred last week in D.C. while he was still conducting the investigation ... and he told us the scandal was just a "reflection of competitive activity between two clubs."

Everybody relax ... MLB commish Rob Manfred says allegations the Red Sox stole signals from the Yankees with an Apple Watch just proves how competitive they are!!!

No, really ... that's what he told us!

We saw the Commish in D.C. this week and asked him about the biggest scandal in baseball -- claims a Red Sox trainer used an Apple Watch to relay Yankees signals to Boston players to give their hitters an advantage.

"Look, I think it's a reflection of competitive activity between two clubs," Manfred told TMZ Sports ... "I'm sure we'll investigate and reach a resolution that preserves the integrity of the game."

When asked if the Red Sox would forfeit the wins from the games in question, Manfred said, "I'm not gonna talk about potential discipline at this point. We haven't even completed the investigation."

Forget Mayweather vs. McGregor ... it was YANKEES VS. TIGERS in Detroit -- when Miguel Cabrera got into a fistfight with Yanks catcher, Austin Romine, and the benches cleared!

Here's the backstory .... Tigers pitcher Michael Fulmer had drilled Yankees star, Gary Sanchez, earlier in the game. Yanks reliever Tommy Kahnle retaliated by throwing behind Cabrera.

Kahnle and Yankees manager, Joe Girardi, were both ejected over the pitch -- but Cabrera was still unhappy and straight socked Romine behind home plate.

Pandemonium ensued ... the benches cleared -- and the Yanks relievers came SPRINTING from the bullpen to join the melee.

Cabrera and Romine were both ejected. The game is still underway ...

Aaron Judge is killin' it, but don't go retiring his number just yet ... so says Yankees legend Reggie Jackson, who told us the rookie phenom still has a lot more to prove.

Mr. October was RAVING about Judge when we ran into him at LAX -- saying he's showing serious signs that he could be one of the best to ever do it -- but notes, "One half season doesn't make a great player."

It's been a helluva 1/2 season -- already racking up 32 HRs (tied for the MLB lead).

But Reggie warns it doesn't get easier -- Judge is gonna have to make some key adjustments if he wants to be one of the greats.

BONUS -- Reggie also talks sex at the end of the clip ... by accident.

YOU'RE KILLIN' ME JUDGE!!!

Actually, NY Yankees star Aaron Judge is murdering sales records for a shirt company -- after he rocked a 'Sandlot' inspired button-up ... and they started flying off the shelves.

After the Yanks beat the Orioles on Saturday, Judge sported "The Great Hambino" shirt to address the media in the locker room ... and people went crazy for his outfit.

In fact, we spoke with the owner of the clothing company, RSVLTS, who tells us Sunday was the company's best sales day ever -- they sold more than TWICE as many shirts as usual (and usual is 100s of units).

Long story short ... Judge is just as hot in the fashion world as he is at the plate.

The New York Yankees are lucky to have Aaron Judge on their squad, 'cause he hits 490-plus-foot home runs ... like this.

The Yankee Outfielder and bonafied slugger hit a BOMB Sunday against Orioles pitcher Logan Verrett in the bottom of the 6th inning at Yankee Stadium ... taking the righty deep at a whopping 496 feet.

It's apparently the longest HR ESPN has recorded since 2009, and certainly the longest in the MLB this year. He's got 21 home runs for the 2017 season so far.

NY Yankees mega-slugger Aaron Judge ... loves musicals!!!

The power-hitting rookie was at CC & Amber Sabathia's PitCCh In Foundation charity event in NYC Monday night when we asked the one thing NY newbies should do when they get to the Big Apple.

His answer -- BROADWAY!!!

The 6'7" superstar even has a favorite play ... and says he keeps some of the songs on his playlist.

Big props from Big Papi ... who says Derek Jeter's jersey retirement ceremony at Yankee Stadium this weekend was so incredible, he hopes to have one just like it at Fenway Park.

David Ortiz was out in NYC when he told us #2's ceremony was "perfect" -- adding, "He deserve it, man."

We also asked the Red Sox legend if Jeter will go down as the greatest Yankee of all time. Papi seemed to sign off on that.

And if baseball's not your thing -- Ortiz also gave us some recommendations on the Dominican food we HAVE to try.

The NY Yankees are FIRED UP about their big 22-year-old outfielder Clint Frazier -- who says Reggie Jackson is personally mentoring him ... even taking him out for froyo!

Frazier was the #5 overall pick in the 2013 MLB Draft -- and some say he could be the next GREAT home run hitter in the majors.

The Yankees are clearly believers -- and when we got Frazier out in NYC, he told us how he's been learning from one of the all-time greats, Mr. October.
