FORT MYERS, Fla. -- Red Sox starter Clay Buchholz left the field after straining his right hamstring while covering first base during a spring training drill Tuesday.

“It’s the best thing that it happened now and not when we’re getting ready to pitch in games,” Buchholz said. “As far as they told, it’s mild as it can be. For how I’m looking at it, get here early and do the treatment on it and hopefully I’m back in the next four or five days.”
