Zac Thornton

Thornton was already the quiet story of the second half; Peralta's trade to Tampa Bay sealed the deal. The 24-year-old lefty owns the No. 3 spot in the Mets' rotation with nowhere to go. Two consecutive scoreless starts before this past week. The ERA will regress slightly — chase the 3.20–3.60 range, not the current 1.93.

Two consecutive scoreless starts since the callup. The 24-year-old lefty looks like a legitimate SP2/SP3 option for the stretch run.

Three straight quality starts since his callup; RotoBaller flagged him as a priority add heading into Week 19 in all formats.

Started @ Pittsburgh Pirates (2W-2L, 2.88 ERA)
