A tough start to September is costing the Boston Red Sox a chance to catch the first-place New York Yankees. Now, as they head to Tampa Bay for a four-game set, the Red Sox must make sure they continue to keep the Rays at bay in the wild-card race. Ricky Romero won for the seventh time in nine starts, J.P. Arencibia hit a three-run homer and the Toronto Blue Jays beat the Red Sox 7-4 on Thursday night, Boston's seventh defeat in 10 games.
