The Cardinals have added a four-time All-Star to their stable of bullpen arms.
The club promoted left-hander Brian Fuentes from Double-A Springfield on Wednesday. The 36-year-old, who was released by Oakland on July 11 and subsequently signed by St. Louis three days later, tossed a scoreless inning for Springfield on Tuesday. He previously made two scoreless appearances while on an injury rehab assignment with the Cardinals' Gulf Coast League affiliate.
Fuentes takes the roster spot of pitcher Victor Marte, who was optioned to Triple-A Memphis. To create space on the club's 40-man roster, the Cardinals designated pitcher Chuckie Fick for assignment.
The Rockies' all-time saves leader, Fuentes was 2-2 with a 6.84 ERA and five saves in 26 appearances for the Athletics this season. He has 204 career saves, including a Major League-best 48 in 2009 for the Angels.
In 43 appearances out of St. Louis' bullpen, Marte was 2-2 with a 4.46 ERA.
