Like most of his teammates, Jacoby Ellsbury has not had the kind of year he would like, especially as a follow-up to last season when he was the American League MVP runner-up. Limited by injury to just 70 games, he entered Tuesday's series opener against the Yankees batting .257, with three home runs, 18 RBI, 37 runs scored, a .363 slugging percentage and .299 on-base percentage. But, he gave the Red Sox and himself something to celebrate on his 29th birthday: a walkoff win, just the third of the season for the Sox. "We've seen a lot of walkoffs this year and we haven't celebrated enough," said manager Bobby Valentine. "I'm happy for the guys. They're all smiling."
