Knizner, 30, has played parts of seven seasons in MLB with the St. Louis Cardinals (2019-23), Texas Rangers (2024) and San Francisco Giants (2025). He’s appeared in 323 career games, with the vast majority coming with St. Louis from 2021-23, posting a .211 career batting average with 33 doubles, a triple, 19 home runs and 90 RBI with four stolen bases, 70 walks and 214 strikeouts.

In 33 games with the Giants last year, Knizner hit .221 with a double, triple, and a home run with five RBI, seven walks and 10 strikeouts.

With Mitch Garver a free agent and Harry Ford traded to the Washington Nationals, Knizner becomes the most likely option to be Raleigh’s backup this season. He’s sparingly played first base as well and could be a reserve option there at times.

Raleigh should continue to be heavily leaned on behind the plate, but Garver appeared in 87 games for Seattle last season as the No. 2 catcher and part-time designated hitter.
