The Twins have announced, via Twitter, they will promote top pitching prospect Kyle Gibson on Tuesday and he will make his MLB debut Saturday. The Twins have optioned left-hander Pedro Hernandez to clear a 25-man roster spot for Gibson.
Gibson, the 22nd overall selection in the 2009 draft, was ranked as the 41st-best prospect in the game by ESPN's Keith Law (Insider subscription required), 45th by MLB.com, and 68th by Baseball America. Gibson underwent Tommy John surgery in 2011 and didn't pitch again until the fall of 2012; but, Law writes "he is back to 92-94 with his four-seamer, and he works down in the zone to keep the ball on the ground as much as possible. His best pitch is a hard slider that he uses to wipe out right-handed hitters but also used in changeup counts against lefties." Baseball America lauds Gibson's changeup as a plus pitch with sink while MLB.com says Gibson's slider "gives him a third above-average offering." The 25-year-old has been solid in Triple-A this year posting a 3.01 ERA, 7.7 K/9, 2.7 BB/9, and 55% groundball rate in 92 2/3 innings covering 15 starts.
Gibson will accrue 97 days of service time, if he remains with the Twins for the rest of the season, and will most likely not be eligible for Super Two status based on the current projection. The Twins will control Gibson through the 2019 season.
