Boston Red Sox pitcher John Lackey claims his first win since 2011

John Lackey pitched six innings of one-run ball as the Boston Red Sox completed a four-game sweep of the Houston Astros with a 6-1 victory at Fenway.

Overbay's go-ahead two-run bomb in the seventh gave the Yankees a four-game sweep of the Blue Jays, their first since 1995.

David Price's first win of the season was overshadowed by a heated exchange with home plate umpire Tom Hallion as the Tampa Bay Rays beat the Chicago White Sox 8-3.
