2026 review

Luis Castillo threw enough innings to matter and gave most of them back: a 5.85 ERA and 1.49 WHIP in 130.2 IP across 29 games with 23 GS, with an 18.9 K% and a 7.4 BB% over 592 BF, 151 H and 25 HR allowed, and a 4-11 record. He started the year with SEA, last pitched for them Jul 28 and made his first appearance for CHW on Aug 6, then was placed on the 15-day IL on Sep 24 with a right shoulder impingement, missing 3 regular-season days with no activation on record. Drafted at NFBC ADP rank 156, he finished 1466th of 1472 in the TDK LABS 5x5 value rank, 1310 spots below, and 230th of 236 starting pitchers. His 5.85 ERA ran 0.83 above his 5.02 xERA over 592 BF, and the months swung hard, a 3.38 ERA in 21.1 IP in Jun against an 8.06 ERA in 22.1 IP in Apr. He moved from the rotation to the bullpen late, with his first appearance in the new role on Sep 12. By early Sep the TDK LABS card was pointing at a rough recent stretch and rising walks; by late Sep it had him on the IL with the shoulder.
