What Each Player's System Trusts
Aroldis Chapman
- babip_againstNOISEBABIP-against 0.231 suppressed and unstable — flattering the ERA
- xeraNOISEluck-free xERA 2.94 is 2.46 above the ERA — regression coming
Jhoan Duran
- xeraNOISEskill near league average (2.34)
Chapman and Duran share identical 3.70 ERA and 1.24 WHIP, but Chapman projects 55 K to Duran's 45 — the strikeout edge is the difference between a sell-high and hold.
