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.
