Red Sox GM Theo Epstein sees the next 17 days as an opportunity. Boston has fallen 3½ games behind the Yankees in the AL East and are only 3½ games ahead of the hard-charging Rays for the wild card. "We have an opportunity ahead of us to play good baseball for two and a half weeks and ride that momentum to the postseason," Epstein said Monday on WEEI sports radio. "If we don't do it, we don't deserve to be there. We have to prove that we are the team that had the best record in baseball for four-plus months, not the team that started 2-10 or has played 3-10 most recently. That's on us. We have to go out and do it."
