Call up RHP Robert Gsellman from AAA Las Vegas.
Don’t let Gsellman’s 5.89 ERA in AAA fool you. The 23 year old’s career minor league ERA of 3.06 is in line with his performance over his past four starts (3.04 ERA). Las Vegas is a part of the Pacific Coast League, notorious for being hitter friendly.
MLB.com ranked Gsellman 14th on the Mets midseason prospect list. He may not over-power hitters like many of the other arms that have come through the Mets system recently, but he maintains good control and generates many ground balls.
MLB.com notes “Gsellman features a really good sinking fastball, one that touches 94 mph and sits in the 91-92 mph range. It’s not an elite-level sinker, but the right-hander does elicit a fair share of ground-ball outs, throwing it downhill from his 6-foot-4 frame.”
He may not fly under the radar and dominate a la Jacob deGrom, but he has the stuff to be a solid back end of the rotation starter. While he may not make many all star teams, he offers more upside than Verrett.
