2026 review

Aroldis Chapman closed all year for BOS and got the outs, but he gave away a lot of free passes doing it: a 1.92 ERA and 1.12 WHIP in 51.2 IP over 53 games, with 35 SV, 2 BS, and a 33.3 K% against a 10.8 BB% over 213 BF. The strikeouts were the separator, as his 33.3 K% over 213 BF was the 14th highest of 517 pitchers with 100+ BF, and he worked every month from Mar through Sep, with his heaviest load 12 games and 12.0 IP in Jul. Drafted at NFBC ADP rank 52, he finished 125th of 1472 in the TDK LABS 5x5 value rank, 73 spots below, and 10th of 575 relievers. His 1.92 ERA ran 0.72 below his 2.64 xERA over 213 BF. By early Jul the TDK LABS card had him as a top closer working through a rough patch.
