The Red Sox clinched the AL East pennant last night at Yankee Stadium, but from the looks of things, you would have thought it was the Yankees celebrating a division win. That’s because in the 9th inning with the Yankees down 3-1, Mark Teixeira launched a grand slam into the right-field bleachers ending in a 5-3 Yankees win.

At 36 years old, Texeira is now one of the oldest Yankees and he’s retiring at the end of the season, so this could be the final home run he ever hits in his career. Up to his at bat in this game, it looked like the Red Sox were going to be able to gloat at Yankee Stadium with an on-field celebration, but Texeira was having none of that.

“I hope this was my last home run. I really do,” remarked Texeira after the game. “That was incredible. These fans. I love you guys.”

The Yankees-Red Sox rivalry has cooled in recent seasons, with the Yankees struggling to get to the post season and the Red Sox taking a commanding lead of the division this year. Meanwhile, classic player rivalries have been absent: Gone are the days of Manny Ramirez vs. Mariano Rivera or even Pedro Martinez vs. bench coach Don Zimmer (that last one is a beaut if you haven’t seen it).

Maybe this will stir things up again, especially with all the hot young talent who arrived mid-season for the Yankees. Either way, this was a heck of a way to go out, Tex.

As for the Red Sox, they won the division anyway when the Orioles beat the Blue Jays. Dustin Pedroia didn’t seem to mind, as the following tweet shows.

He’s going to the playoffs either way.
