2026 review

Mark Leiter Jr. was ATH's swing-and-miss reliever, working exclusively in relief with a 4.28 ERA and 1.31 WHIP in 33.2 IP, a 26.4 K% and a 7.6 BB% over 144 BF, with 4 SV, 5 HLD and 2 BS across 36 games. A right hip impingement sent him to the 15-day IL on Jun 20, he was activated Jul 3, then the same injury put him back on the 15-day IL on Jul 21 before he was transferred to the 60-day IL on Jul 30, missing 85 regular-season days in 2 stints. Drafted at NFBC ADP rank 1088, he finished 658th of 1472 in the TDK LABS 5x5 value rank, 430 spots above, and 281st of 575 relievers. His 31.4 CSW% over 551 pitches was the 33rd highest of 517 pitchers with 100+ BF. The TDK LABS card had him on the 60-day IL after surgery by late Aug.
