With 21 starts in the 2022 season, the pair would break the all-time MLB record (since 1908) for starts as a battery.
Legendary Detroit Tigers battery Mickey Lolich and Bill Freehan are the current holders of the record, at 324 career starts together from 1963-75. The Boston and Milwaukee Braves tandem of Warren Spahn and Del Crandall had the second-most starts as a battery at 316 from 1949-63.
Wainwright and Molina have been teammates since the 2005 season, when Wainwright made his MLB debut. Wainwright made his first start on April 6, 2007.
Molina said 2022 will be his final season in the majors. Wainwright has left the door open to continue pitching.
