Clay Buchholz pitched on Sunday for Lowell. Threw 38 pitches over an inning. He allowed three runs on a hit, and three walks. I'm not reading a lot into this start, seeing as it was his first since his injury. He makes one more rehab start, and is projected to come off the DL against the Tigers on September 4th. Matt Moore is coming off the DL on September 3rd against the Angels.
Buchholz will likely bump Dempster, and Moore will likely bump Hernandez. A big factor in deciding the race could be which starter returns to form the fastest. BP has the Red Sox at 93.5 wins, and a 60% chance to win the division. It has the Rays at 92.6 wins, with a 37% chance to win the division. Fangraphs is at 94 wins for Boston, 93 for Tampa. It's possible we could see a one-game playoff to determine who wins the East.
