Castellanos had two opt-out clauses in his four-year, $64 million deal, but he did not exercise the first one after the pandemic-shortened 2020 season.
“I don’t think we’re not going to sign players on the free-agent market,” said Krall, who addressed the team’s offseason plan after Wednesday’s trade of veteran catcher Tucker Barnhart to the Detroit Tigers.
Castellanos, 29, will enter free agency coming off one of the best seasons of his nine-year career.
