2026 review

Mason Adams posted a 4.03 ERA and 1.48 WHIP in 29.0 IP over 6 starts for COL, striking out 31 and walking 12 with a 25.0 K% and a 9.7 BB% over 124 BF, though his 43.8 Hard% over 80 BBE was the 7th highest of 517 pitchers with 100+ BF. COL selected his contract Aug 25, and he worked 2 games for 9.0 IP in Aug before 4 games for 20.0 IP in Sep. Undrafted in NFBC drafts, he finished 821st of 1472 in the TDK LABS 5x5 value rank, 518th of 811 pitchers, and 123rd of 236 SPs. His 4.03 ERA ran 1.06 below his 5.09 xERA over 124 BF. Right after his call-up in late Aug, the TDK LABS card described him stepping into the rotation and read the contact he was allowing as heavy; by late Sep it had shifted to crediting him for limiting hard contact and building a strong stretch of innings despite pitching in a hitter-friendly home park.
