Mazza made his MLB debut last year, throwing 16 1/3 innings of 5.51 ERA ball over nine outings. He was better in the upper minors, working in the mid-three ERA range in stints at the Double-A and Triple-A levels. Mazza has a penchant for drawing groundballs on the farm, though he’ll need to prove he can do so consistently in the bigs if he’s able to earn his way back up.
Wacha tells reporters that he expects to function as a starter in New York. Indeed, that was a key factor in his decision, he suggested. (Via MLB.com’s Anthony DiComo, on Twitter.) With Rick Porcello also set to join the staff on the same premise, it seems the Mets will at some point strike a trade involving another starter (or have some explaining to do).
