2026 review

Martín Pérez was a workhorse lefty for ATL, posting a 9-9 record with a 3.04 ERA and 1.27 WHIP in 142.0 IP across 26 GS, with a 17.1 K% and 10.4 BB% over 596 BF. He signed a minor league contract Feb 4, had it selected Mar 30, was designated for assignment Apr 12 and outrighted Apr 14, then signed again Apr 15 before that contract was selected Apr 17. A left forearm contusion sent him to the 15-day IL Jul 6, activated Jul 22, missing 22 regular-season days in that stint plus a second 15-day IL placement Sep 24 for low back inflammation. Drafted at NFBC ADP rank 921, he finished 354th of 1472 in the TDK LABS 5x5 value rank and 56th of 236 SP. His 3.04 ERA ran 1.47 below his 4.51 xERA over 596 BF, and he pitched better after the forearm stint, a 3.54 ERA in 81.1 IP before it and a 2.37 ERA in 60.2 IP after. The TDK LABS card called the move mere filler in early May, saw him settling in as a steady volume lefty against a lineup that struggled versus left-handers by late Jun, flagged a strong recent run alongside slipping underlying numbers by late Aug, and had him on the 15-day IL with low back inflammation by late Sep.
