Cubs claimed RHP Gavin Hollowell off of waivers from the Diamondbacks.
The 26-year-old hurler was subsequently optioned to Triple-A Iowa where he’ll begin his tenure with the Cubs. Hollowell has spent the majority of the season at the Triple-A level where he has compiled a 5.70 ERA, 1.65 WHIP and a 33/18 K/BB ratio across 23 2/3 innings. He’ll add bullpen depth in the upper minors for the Cubs.
