San Francisco, CA (SportsNetwork.com) - The San Francisco Giants activated pitcher Jeremy Affeldt from the 15-day disabled list on Wednesday.
Affeldt landed on the disabled list prior to Opening Day due to a sprained medial collateral ligament in his right knee. The left-handed reliever went 1-5 with a 3.74 ERA for the Giants last season in 39 appearances.
The Giants optioned outfielder Juan Perez to Triple-A Fresno to make room for Affeldt on the roster. Perez failed to register a hit in eight games this season.
