The Red Sox got a bit of a scare on Tuesday when Clay Buchholz left the field after aggravating his hamstring covering first base. Thankfully, the 28-year-old pitcher is fine and should return in four to five days.

Buchholz said he was told the hamstring tweak is “as mild as it can be.” The righty mentioned he may have been trying to overdo it on Tuesday, but that the injury is nowhere near as severe as the pulled hamstring he suffered in 2010 that forced him to miss almost a month of action.

Buchholz said he’s pulled his hamstring in the past, and he knew right away that this was not a spring training-ending injury. Buchholz went 11-8 last season with a 4.56 ERA. His started a career-high 29 games.
