2026 review

Yuki Matsui was a lefty reliever who missed time early then posted results well ahead of his process, a 1.83 ERA and 1.14 WHIP in 64.0 IP over 54 games, but his 13.8 BB% over 260 BF was the 34th highest of 517 pitchers with 100+ BF. He struck out 68 with a 26.2 K% over 260 BF, walked 36, and posted 5 W, 1 SV and 11 HLD. A left groin strain put him on the 15-day IL Mar 25, he took a rehab assignment Apr 4, and was activated May 5 after missing 41 regular-season days. Drafted at NFBC ADP rank 545, a rare pick taken in 1 of 674 drafts, he finished 242nd of 1472 overall in the TDK LABS 5x5 value rank, 77th of 811 pitchers and 41st of 575 relievers. His 1.83 ERA ran 1.20 below his 3.03 xERA over 260 BF. He was tougher on left-handed batters, .140/.232/.223 over 138 PA, than on right-handers, .202/.344/.394 over 125 PA. His best month was May at a 0.60 ERA in 15.0 IP and his worst was Jul at a 4.38 ERA in 12.1 IP. The TDK LABS card had him as a low-leverage lefty in May, a middle-relief southpaw by Sep 9, and by late Sep flagged his ratios running well ahead of his underlying numbers.
