BOSTON (AP) - Jon Lester struck out a career-high 15, allowing one hit over eight scoreless innings and pitching the Boston Red Sox over the Oakland Athletics 6-3 on Saturday.
Jonny Gomes hit a grand slam and David Ortiz and David Ross added solo homers in Boston's second straight win after losing a day-night doubleheader to Tampa Bay on Thursday.
The only hit off Lester (3-4) was Craig Gentry's leadoff bloop single in the third over the head of second baseman Dustin Pedroia.
Lester rebounded from taking the loss in his previous two games by striking out nine of his first 13 batters. His previous strikeout best was 13 in 2010 during a loss at Seattle.
Oakland scored three runs in the ninth against Chris Capuano. Koji Uehara closed for his seventh save in seven opportunities.
Gomes hit his slam in the first inning off Tommy Milone (0-3).
