The 200-inning starter is practically extinct. Just five pitchers cleared the threshold in 2023, down from 36 in 2013, 44 in 2003 and 52 in 1993. Even 190 innings has become a rarity. Last season, 18 teams had zero starting pitchers throw 190 innings. Ten teams had one. The Phillies had two: Aaron Nola (193 2/3 IP) and Zack Wheeler (192 IP).

The Seattle Mariners, though, had three: Luis Castillo (197 IP), Logan Gilbert (190 2/3) and George Kirby (190 2/3 IP).

No team’s starting pitchers logged more innings last year than Seattle’s 901 1/3.
