The Cardinals recalled Crooks from Triple-A Memphis on Friday.
The 24-year-old will join the big-league roster after posting a .262/.412/.567 slash line with 13 homers in 39 games for Memphis. Yohel Pozo was optioned to Triple-A in a corresponding move. It's not clear how much playing time Crooks will get, as Ivan Herrera and Pedro Pages have split most of the starts at catcher this season, but Pages' .622 OPS in 125 plate appearances could make him the odd man out.
