BOSTON -- The Red Sox placed left-hander James Paxton on the 15-day injured list Monday with a strained right calf, a day after he limped off the field in the first inning following a quick move trying to cover first base.
"MRI this morning, they got the results," manager Alex Cora said before Boston faced the Texas Rangers in the opener of a three-game series. "He's in pain. We'll see what happens."
Paxton, 35, was on crutches after Monday night's game, which the Red Sox won 5-4 on Rob Refsnyder's walk-off single in the 10th inning.
