Rosario was recalled to the majors prior to Friday's game against the Giants, MLB.com's Jenifer Langosch reports.
Rosario hasn't played any games at the big-league level this season, following 20 appearances with the Cardinals in 2016. During 50 games with Triple-A Memphis this year, he's slashed .247/.291/.279 with 23 RBI. Rosario will provide depth at the catcher's position behind Yadier Molina and Carson Kelly.
