The team says Kottaras likely will be added to the 25-man roster Saturday in Milwaukee. St. Louis begins a three-game series Friday against the Brewers. Kottaras was batting .286 with three homers and four RBIs in 10 games for Cleveland.
The Cardinals also activated starter Joe Kelly following a stint on the 60-day disabled list because of an injured left hamstring. He is to start Friday in Milwaukee, where he was hurt April 16.
