Heralded prospect Oscar Taveras will join the St. Louis Cardinals from Class AAA Memphis on Saturday before the Cardinals play San Francisco at 1:15 p.m. at Busch Stadium.
Cardinals manager Mike Matheny annouced after his team's 9-4 loss to the Giants on Friday that first baseman Matt Adams will be placed on the disabled list with a calf injury, opening the door for Taveras to join the team.
The left-handed-hitting Taveras, 21, isn't likely to be used as bench depth. The Cardinals are expected to start him in center field, a position that has been filled by light-hitting Peter Bourjos and, more recently, Jon Jay.
Taveras was batting .325 with 15 doubles, seven home runs and 40 RBIs in 49 games at Memphis. He has an on-base percentage of .373 and a slugging percentage of .524.
Adams is batting .325 with 16 doubles, three homers and 17 RBIs in 52 games. He hasn't played since Wednesday when he struck out as a pinch-hitter in a 7-4 loss to the New York Yankees.
