The Mariners announced that right-hander Trent Thornton has been reinstated from the 15-day injured list. To make room on the active roster, the M’s have once again designated righty Casey Lawrence for assignment.
Thornton returns after missing a month due to appendicitis. The righty has allowed five homers in only 15 1/3 innings of work out of the Mariners’ bullpen, which has been the biggest culprit in Thornton’s 5.87 ERA. A 16.9% strikeout rate also hasn’t helped, but in something of an all-or-nothing statistic, Thornton has a career-best 51% grounder rate and a .250 BABIP, so he has been successful when he has been able to keep the ball in the park.
In under two months’ time, Lawrence has already made an early bid for MLBTR’s most written-about player of 2025. Lawrence has been designated for assignment six times in the last eight weeks, with Seattle logging five of those DFAs and the Blue Jays the other instance. The right-hander has cleared waivers five of those six times (except for when the Jays claimed him away from the Mariners), and on three occasions Lawrence elected free agency before quickly re-signing with Seattle.
Chances are that Lawrence’s latest trip to DFA limbo will again result in the right-hander staying with the M’s, whether he just accepts an outright assignment or if he again clears waivers, elects free agency, and re-signs a new minor league deal. Throughout this transactional whirlwind, Lawrence has also posted a 4.08 ERA over 17 2/3 innings with Seattle and Toronto, with only an 8.8K% but also a tiny 1.3BB%.
