Manager John Farrell described it as a “mild strain” and said the right-hander was day to day.
“He’ll get re-evaluated tomorrow and then we’ll have a better read on how many days he’s going to need treatment,” Farrell said. “It was a mild strain but enough to get him off the field.”
Buchholz called it “just a tweak” and didn’t anticipate missing any spring starts.
“I’ll get the treatment on it and hopefully I’ll be back in four or five days,” Buchholz said.
Running off the mound during drills on Tuesday morning, he fielded a ground ball and was headed toward first base when he came up lame. The right-hander sat on the ground for a few minutes massaging his hamstring and was told to return to the clubhouse. He was followed by a trainer and seemed visibly disappointed.
Buchholz missed a month with a left hamstring injury suffered in 2010, but said this one was nothing compared to the prior injury.
“I’m able to walk around. I couldn’t even walk the last time it happened in 2010,” Buchholz said. “It was a different leg, go figure. I don’t feel like it’s going to take a lot of time.”
The injury occurred during the first official workout for Red Sox pitchers and catchers.
“It’s one thing if it’s during the season, but you’ve got to know your limits out here, especially being the first day,” Buchholz said. “I figured I’d come in here and let them take a look at it and that’s when they told me it wasn’t anything bad. ...They wouldn’t even classify it as a pulled muscle, it’s more of a strain.”
