Clay Buchholz felt exhausted after throwing only 76 pitches. His return to the mound for the Red Sox after nearly a month on the disabled list was a test by an aggressive Seattle offense that had battered Boston pitching the first two games of the series. "They made me work hard," Buchholz said. "I knew they were swinging. That's about the most aggressive team that I've pitched to in my career. For the number of pitches that I threw, that was a grinding, stressful outing, knowing I can't make a mistake." Buchholz pitched into the eighth inning in his first start since late May, David Ortiz gave him cushion from the start with his 449th career home run in the first inning and Boston avoided being swept with a 5-4 victory over the Seattle Mariners on Wednesday night.
