Buster Posey will remain the San Francisco Giants' "primary catcher" in 2021 and will get "the lion's share of the reps" behind the plate, according to Gabe Kapler.

Posey is owed $21.4 million in what could be the final year of his contract. He sat out 2020 amid concerns about the coronavirus pandemic after he and his wife adopted twin girls who were born prematurely.

Joey Bart, considered one of baseball's top prospects before the season, was called up to temporarily replace Posey and struggled through a .233/.288/.320 slash line in 111 plate appearances.

"I don't think it's any secret that last year was a struggle for Joey on a number of different levels," Kapler said. "We think the development that he had, the development time that he had at the major league level, was really good for him. And we'll continue to assess his readiness and just think about Buster as a sure-fire lock for our Opening Day roster and the lion's share of the reps back there."
