Which Diamondback has the most batters-faced/plate-appearances in their career? Merrill Kelly pitched to 8594 batters so far, per Baseball Reference. And I’m not sure whether that included the 91 batters he faced in the postseason. It included 2234 batters in the minors, 3212 batters “foreign”, and 3085 batters in the Majors (plus “other”).
On the position player side, Ketel Marte’s 6375 plate appearances were the most. It included 2289 batters in the minors, 133 batters “foreign”, and 3953 batters in the Majors.
Introduction.
When a batter faces the starting pitcher more than once in the same game, each time he steps to the plate is a plate appearance.
