San Francisco, CA -- (Sports Network) - The San Francisco Giants activated reliever Keiichi Yabu from the 15-day disabled list Wednesday and recalled pitcher Billy Sadler from Triple-A Fresno.

Yabu was 3-4 with a 3.64 earned run average in 40 games with the Giants before being shelved on July 20 with a strained middle finger on his right hand.

Sadler was 0-1 with a 4.94 ERA in a 19-game stint with the Giants earlier this year.

To make room for both players, San Francisco optioned reliever Osiris Matos to Fresno and designated right-hander Sergio Romo for assignment.
