2026 review

Luis Gastelum missed bats as a rookie reliever for STL, posting 5 wins and 4 losses with a 4.42 ERA and 1.25 WHIP in 36.2 IP, a 28.9 K% and a 7.9 BB% over 152 BF across 34 games, with 1 HLD and 2 BS. STL selected his contract Jul 8, and he pitched from there through Sep 25. Drafted at NFBC ADP rank 515, he finished 443rd of 1472 overall in the TDK LABS 5x5 value rank, 198th of 811 pitchers, and 131st of 575 relievers. His 32.2 CSW% and 15.4 SwStr% over 599 pitches ranked 18th and 22nd highest of 517 pitchers with 100+ BF. He was best in Sep, a 3.09 ERA in 11.2 IP, and worst in Jul, a 6.30 ERA in 10.0 IP. The TDK LABS card followed him from a promoted arm with a strikeout pedigree in mid Jul to, by early Sep, a middle reliever bouncing between dominant and rough outings in a bullpen with no fixed save or hold role.
