The Mariners have announced they’ve claimed righty Pat Light from the Pirates and assigned him to Triple-A Tacoma. They’ve also outrighted righty Ryne Harper to Triple-A Tacoma.
The Pirates designated Light for assignment last Saturday. The reliever is a former first-round pick of the Red Sox and has tantalizing velocity, but he has long struggled with his control, as his 5.1 BB/9 this year for Triple-A Indianapolis suggests. The 26-year-old pitched briefly in the big leagues for the Red Sox and Twins last season and allowed 22 runs in 16 2/3 innings, though he did average 95 MPH with his fastball.
