Essentially, for this entire Division Series the Orioles and the Yankees have been within one run of each other; the only exception is the ninth inning of Game 1, when the Yankees hammered Jim Johnson.
This game, of course, was scoreless until the bottom of the fifth, when Mark Teixeira stole a base for the first time since he was in high school and Raul Ibanez hit a ball that would have been a double play if Teixeira had still been on first base, but instead was an RBI single.
It's just been one of those series when every inch or three seems to matter.
The umpires looked at the video and it's possible that the baseball just nicked the fair pole on its way to the stands. But there's certainly no compelling evidence until someone finds the ball and sees some yellow paint. So a foul ball it was, and McLouth struck out on the very next pitch to end the inning.
The Yankees are ahead 1-0 in the bottom of the sixth, and the time for more Orioles magic is growing short.
