Yankees' Harrison Bader Chugs Three Beers At Once To Celebrate AL East Title

Harrison Bader took a page out of Stone Cold Steve Austin's playbook on Tuesday night -- chugging three beers at once to celebrate the Yankees winning the AL East title ... and it was EPIC!!!

The New York outfielder -- who's only been a member of the Pinstripes for a few weeks after being acquired by the team in a trade with the Cardinals last month -- was seen hitting the party trick in the locker room following NY's 5-2 win over the Toronto Blue Jays.

The 28-year-old nabbed three Bud Heavies, cracked 'em all open, then proceeded to pour each one down his face. At one point, one of his teammates even threw ANOTHER beer into the mix!!

Following the initial chug, Bader let out a burp -- and then went back for more!

Of course, he wasn't the only Yank gettin' after it following the big victory ... the team's MVP, Aaron Judge, was also spotted in the locker room enjoying a face full of champagne.

Judge didn't hit any homers in the contest -- he walked FOUR times and still remains one dinger shy of tying Roger Maris' 61 mark -- but he clearly didn't care ... even opting to sip on a Bud later in the celebration.

No word when the guys finally wound down the celly -- but it had to have wrapped up sooner than later ... they've got a game Wednesday at 4 p.m. PT.
