The Boston Red Sox placed starting pitcher Nathan Eovaldi on the 15-day injured list Sunday with inflammation of his lower back.
The move was made retroactive to June 9.
Eovaldi is 4-2 with a 3.16 ERA and 72 strikeouts in 12 starts this season. The right-hander hasn't allowed a run in his past two starts, including on Wednesday night when he pitched five innings, allowing six hits and striking out five in Boston's 1-0 victory over the Los Angeles Angels.
He is the second member of the Red Sox's rotation to be placed on the injured list in recent days.
