2026 review

Mason Barnett spent the year jumping between the bullpen and, late, the rotation, posting a 7.02 ERA and 1.66 WHIP in 50.0 IP for ATH, with a 21.8 K% and a 13.1 BB% over 229 BF across 20 games (6 GS), 1 W, 4 L and 2 SV. He shuttled between the majors and the minors on Mar 9, Apr 18, Apr 20, May 13, May 15, Jun 2, Jul 15, Jul 22, Aug 18 and Sep 18. Drafted at NFBC ADP rank 561, he finished 1280th of 1472 in the TDK LABS 5x5 value rank, 778th of 811 pitchers and 569th of 575 relievers. His 7.02 ERA ran 1.93 above his 5.09 xERA over 229 BF. His 13.1 BB% over 229 BF was the 49th highest of 517 pitchers with 100+ BF. Once he moved into the rotation on Jul 30, a 9.24 ERA in 25.1 IP as a starter followed a 4.74 ERA in 24.2 IP as a reliever. His best month was Jun at a 1.35 ERA in 13.1 IP and his worst was Aug at a 13.09 ERA in 11.0 IP. The TDK LABS card had him back as middle-relief depth in mid-May, then as a recalled rookie up against one of the league's tougher opponents by late Sep, given another start despite weak overall numbers.
