Red Sox' Koji Uehara diagnosed with strained pectoral

Boston Red Sox relief pitcher Koji Uehara has been diagnosed with a strained right pectoral muscle.

What It Means:

Uehara was lifted after his seventh pitch of the game, and while Boston's manager John Farrell didn't give any sort of timetable or details about the injury, time on the disabled list seems like a likely outcome.

Uehara is having a much better season than his 4.50 ERA might indicate, and is sporting a 2.55 SIERA with a 35.2 percent strikeout rate. We project him to post a 3.24 ERA over the remainder of the season.
