Mariners rookie starter Taijuan Walker will make his final start of the 2013 season against the Astros on Monday, reports MLB.com’s Greg Johns. Brandon Maurer will take his spot in the rotation.
Walker spent most of his season between Double-A Jackson and Triple-A Tacoma, posting an aggregate 2.93 ERA in 141.1 innings. He made his Major League debut on August 30 against the Astros, shutting them out on two hits and a walk in five innings. His second start didn’t go as well, as he allowed four runs to the Royals in five frames.
MLB.com ranked Walker, drafted by the Mariners 43rd overall in the 2010 draft, as the #5 overall prospect entering the season. He is expected to be a mainstay in the Seattle rotation starting next season.
MASN’s Roch Kubatko reports that the Orioles granted infielder Paul Janish his release from his Triple-A contract. He will retire and join the coaching staff at Rice University.
Janish, 34, played parts of nine seasons in the majors with the Reds, Orioles, and Braves. He hit .212/.280/.284 over his career, providing most of his value through his fielding and versatility. While he logged most of his time at shortstop, he also played third base and second base and also pitched on two occasions in blowout losses.
The Diamondbacks announced that outfielder Yasmany Tomas will undergo season-ending core muscle surgery on Tuesday in Philadelphia. Tomas has been on the disabled list since June 3 with right groin tendinitis and experienced multiple setbacks during his rehab.
Tomas, 26, was in the midst of a disappointing year before the injury, batting .241/.294/.464 with eight home runs and 32 RBI in 180 plate appearances.
The Diamondbacks acquired J.D. Martinez from the Tigers a month ago to help fill the gap in the outfield. Prior to that trade, Chris Herrmann and Daniel Descalso were handling left field. The D-Backs entered Monday’s action holding the second Wild Card slot in the National League by 2.5 games over the Brewers and trailed the Rockies by one game for the first slot.
