I just looked at Max Scherzer's age 24 season, 4.12 ERA (Berrios - 3.84), 3.87 FIP (3.90), 9.2 K/9 (9.5) 2.76 SO/W (3.31) 174 SO (202), 170 IP (192.1). Similar, if not slightly better numbers, he could, and with his work ethic, should improve throughout his career. As long as he stays healthy I think he will be good for an extended period of time.
