His numbers on the season look good until you check under the hood. He has thrown 29 innings with a 2.48 earned run average. However, his 17.5% strikeout rate and 12.5% walk rate are both subpar figures. His 51.3% ground ball rate is pretty good but he has largely benefitted from a .197 batting average on balls in play and 89.5% strand rate.
The Mariners have agreed to a minor league contract with right-hander Guillo Zuñiga, per the team's transaction log at MLB.com. The former Cardinals and Angels reliever had been with the Phillies on a minor league deal but was granted his release earlier in the week. Zuñiga, 26, has pitched in the majors in each of the past two seasons, totaling 19 2/3 frames between St. Louis and Anaheim. He's allowed 11 earned runs (5.03 ERA) on 16 hits and eight walks with a dozen strikeouts.
