Foster GriffinWSN · CLE · SP

2026 review

Foster Griffin was a steady rotation innings-eater who kept the ball down enough to beat his contact: he posted a 3.60 ERA and 1.21 WHIP in 172.2 IP with a 21.9 K% and a 6.2 BB% over 721 BF, going 15-6 with 158 SO across 31 starts for WSN and CLE. He last pitched for WSN on Jul 31 and first for CLE on Aug 6, with no transaction listed for the move. Drafted at NFBC ADP rank 999, he finished 255th of 1472 in the TDK LABS 5x5 value rank, 744 spots above, and 39th of 236 starting pitchers. His 3.60 ERA ran 0.75 below his 4.35 xERA over 721 BF, and he posted a 1.15 ERA in 31.1 IP in Jun against a 6.87 ERA in 18.1 IP in Sep. In early May the TDK LABS card read him as a high-volume arm settled into a groove, unremarkable but steady. By early Jul it had him running elite strikeout stretches while the flyball profile bled home runs, and by late Aug it called him effective since the move with pitch counts trending upward. By late Sep the card had him as a reliable starter with command and a season-long role, with modest strikeout totals keeping him more a floor arm than a ceiling one.
