The Mariners announced that they’ve selected the contract of left-hander Ross Detwiler from Triple-A Tacoma and designated infielder Zach Vincej for assignment to open space on the 40-man roster. Righty Chasen Bradford was optioned to Tacoma to open a spot for Detwiler on the active roster.
The move will give the Mariners some important length in the bullpen, as Ryan Divish of the Seattle Times tweets that Mike Leake has been scratched from tonight’s start due to illness. Reliever Nick Vincent will start in his place, so the Mariner look to have a bullpen day on their hands with Leake unable to take the ball.
Detwiler, 32, returns to the big leagues after spending the entire 2017 season at the Triple-A level between the Athletics and the Cubs. The former No. 6 overall pick was a solid back-of-the-rotation arm for the Nationals earlier in his career and had success out of the Nationals’ bullpen in 2014 as well. However, his career took a turn for the worse following a trade to the Rangers in 2015, and he was clobbered for a combined 6.73 ERA in 107 innings between Texas, Atlanta, Oakland and Cleveland from 2015-16.
Detwiler opened the 2018 season with the York Revolution of the independent Atlantic League and pitched 30 strong innings before the Seattle organization purchased his rights. In 71 1/3 frames with Tacoma, he’s posted an uninspiring 5.15 ERA with a 46-to-24 K/BB ratio. He was slated to start tonight before being scratched from his start, though, and since he’s been working in the rotation anyhow, he could enter the game in relief of Vincent and give the Mariners several innings.
Vincej, 27, went 2-for-4 in his lone game with the Mariners earlier this season but has spent the rest of the year in Tacoma. An offseason waiver claim out of the Reds organization, he’s capable of playing multiple infield positions and has batted .246/.314/.346 with six homers, 13 doubles and a pair of triples in 391 plate appearances so far in Tacoma. He’s a former 37th-round pick (Reds, 2012) who owns a career .268/.336/.359 batting line in the minors while playing shortstop, second base and third base.
