Merced, CA (Sports Network) - Relief pitcher Brian Fuentes, who spent last season with the Oakland Athletics and St. Louis Cardinals, has retired from baseball.

Fuentes' hometown paper, The Sun-Star, reported on Thursday that the 37-year- old officially called it quits over the weekend, bringing an end to a 12-year career.

Fuentes hadn't pitched since Aug. 8, when he took the mound for the Cardinals against San Francisco. Following that appearance, he requested leave from the club to attend to a family matter, was placed on the restricted list, and never pitched again. The left-hander was released by Oakland on July 11 and picked up three days later by the defending champions.

He finished with a 2-2 record and 7.20 earned run average in 30 innings over 32 combined games.

A former late-round draft pick of the Seattle Mariners in 1995, Fuentes ended his pro career with a 26-43 mark, 3.62 ERA in 650 appearances for the Mariners, Rockies, Angels, Twins, A's and Cards.
