Matt Thornton is headed to the disabled list with an oblique strain just 10 appearances after the Red Sox acquired him from the White Sox.
Thornton mostly worked the eighth inning for Boston, so the bullpen will have to reshuffle a bit in his absence. And based on the usual recovery timetable for oblique injuries–which can often linger much longer than initially expected–the impending free agent may not pitch again until September.
Thornton suffered the injury Sunday and had hoped to avoid the DL, but Pedro Beato has been recalled from Triple-A to take his place in the bullpen.
Evan Grant of the Dallas Morning News reports that reliever Shawn Tolleson is retiring from baseball. The right-hander experienced a setback in his recovery from Tommy John surgery last week.
Tolleson, who turns 31 years old on Saturday, last pitched in the majors in 2016. He had two very good years out of the bullpen for the Rangers in 2014-15, posting an aggregate 2.88 ERA with 145 strikeouts and 45 walks across 144 innings.
Tolleson signed a one-year deal with the Rays in January 2017 before undergoing Tommy John surgery several months later. The Rangers inked him to a minor league contract in December 2017, but he wasn’t able to work his way back.
