2026 review

Ryan Zeferjahn was a strikeout-heavy reliever who also walked too many hitters: a 3.88 ERA and 1.28 WHIP in 69.2 IP for LAA and CHC over 65 games, with 7 SV and 14 HLD but 4 BS. His 30.9 K% and 13.2 BB% over 304 BF sat on opposite ends of the pool, the K% the 30th highest of 517 pitchers with 100+ BF and the BB% the 47th highest, while his 26.9 Hard% over 160 BBE was the 40th lowest of that same pool. He moved from LAA to CHC, last playing for LAA Aug 2 and first for CHC Aug 4. Taken in just 66 of 674 drafts at ADP rank 986, he finished 387th of 1472 overall in the TDK LABS 5x5 value rank and 159th of 811 pitchers, and 100th of 575 relievers. His ERA ran 0.78 above his 3.10 xERA in 303 BF. Right-handed batters managed only .186/.303/.271 over 166 PA against him, while lefties hit .207/.346/.387 over 137 PA. His best month was Jun at a 0.66 ERA in 13.2 IP, his worst Apr at a 6.28 ERA in 14.1 IP. The TDK LABS card tracked him from a shared-save role with LAA in Jul to closing outright for the Cubs by late Sep.
