Teixeira belts walk-off grand slam to rain on Red Sox party

Mark Teixeira made sure the Boston Red Sox weren't going to celebrate on the field at Yankee Stadium.

When the Toronto Blue Jays lost to the Baltimore Orioles earlier Wednesday night, Boston automatically clinched top spot in the American League East.

So, a game that was initially intense suddenly became a moot point. Still, the Red Sox would've liked to end it on a high note, especially against the New York Yankees.

But with Boston up 3-1 in the bottom of the ninth, Teixeira stepped up to the plate with the bases loaded and ripped a walk-off grand slam.

Though the Red Sox ultimately get the last laugh, their walk-off loss makes for a more awkward celebration in the locker room.
