Ryan Dempster celebrates World Series win by throwing batting practice at 3 a.m.

After the Boston Red Sox won the World Series Wednesday night, where did Ryan Dempster celebrate?

Why at Fenway Park, of course … on the field … throwing batting practice … at 3 in the morning.

That's him on the mound there, throwing to actor Mike O'Malley, who learned something in the wee hours of the morning: #takeoffweddingringwhilehittingwithwoodenbatandnoglovesouch

Per Bob Nightengale of USA Today:

Red Sox pitcher Ryan Dempster, wearing street clothes, is actually on the mound, pitching to his family and friends.

It is 2:57 a.m.

Security keeps making announcements for them to leave, but no one's listening. It took two hours just to clear family and friends from the Red Sox clubhouse so the players could shower.

Guess yelling, "You don't have to go home, you just have to get out of here," doesn't work with newly crowned world champions.

Anyway, Dempster did eventually leave Fenway sometime after three, as our own Mike Oz caught up with him signing autographs outside the park around 3:45 a.m.

Let's hope he wasn't late to his day job: delivering the mail.
