The Mariners announced that they have selected the contract of infielder/outfielder Jason Vosler. Fellow infielder Ryan Bliss was optioned in a corresponding move. There was already a vacancy on the club’s 40-man roster due to right-hander Mike Baumann recently being designated for assignment and traded to the Giants.
Vosler, 30, signed a minor league deal with the M’s in the offseason and has been with Triple-A Tacoma all year so far. In 89 games with the Rainiers, he has hit 20 home runs and drawn walks in 8.4% of his plate appearances, striking out at a 21.6% clip. His .289/.357/.526 batting line amounts to a wRC+ of 113 in the heightened offensive environment of the Pacific Coast League.
Offense has been an issue for the Mariners all year, as they are hitting .218/.299/.367 as a team. That translates to a wRC+ 94, better than just nine clubs in the league. Seattle’s 28% strikeout rate is the worst in the majors by a significant margin, as the Athletics and Rockies are the nearest clubs at 25.7%.
Vosler has been playing the four corner spots this year and those are certainly positions where the Mariners could use some help. First baseman Ty France has a subpar line of .223/.312/.350 and 96 wRC+. The M’s are clearly willing to move on from him as he has reportedly been placed on waivers as the club hopes someone claims him for nothing but cost savings. Josh Rojas has been getting the bulk of playing time at third base and had a hot start but has since cooled, slashing .184/.269/.270 since May 15. In the outfield corners, Víctor Robles and Luke Raley have been doing well but Mitch Haniger is hitting .208/.287/.335 this year.
Ideally, Vosler will come up and give the lineup a boost. He’s played more first base than anywhere else this year and could simply take playing time away from France, who could perhaps wind up in the short side of a platoon. Despite his rough season overall, the righty-swinging France is still hitting .237/.356/.395 against lefties for a 123 wRC+, thanks to drawing walks at a 12.2% rate against southpaws compared to a 6.8% against righties.
Vosler hits from the left side and could perhaps shield France from right-handers. Vosler has slashed .303/.364/.590 against righties this year compared to .253/.339/.364 against lefties. But his defensive versatility will also give Scott Servais some flexibility in how he gets him into the lineup.
This will be Vosler’s third big league team of his career, as he has 97 games of experience with the Reds and Giants. He’s hit just .210/.279/.408 in the majors but has generally fared better at the Triple-A level. He has one option season remaining and can be sent down to the minors later without being exposed to waivers. He also has less than a year of service time and can stick around for a while if he puts up some decent numbers.
