Wilson, 29, who has not pitched since Aug. 15 because of a strained right elbow, will be eligible to return to the team on Aug. 31. The three-time All-Star has 35 saves in 40 opportunities and a 6-4 record this season.
Wilson, who already is signed for next season at $8.5 million, had 48 saves last season to lead Major League Baseball and six more in the postseason as the Giants won their first championship since 1954. He also began this season on the disabled list with a strained left side.
“Nobody wants to go on the disabled list right now. But we have to take care of him,” Giants head athletic trainer Dave Groeschner told reporters. “It’s not just these next six weeks, it’s the next year and the year after.”
San Francisco currently has nine players on the disabled list, including catcher Buster Posey and outfielder Carlos Beltran -- who was obtained in a July trade from the New York Mets in an effort to spark the team’s offense, which ranks last in the National League with 439 runs scored this season.
The Giants (68-60), who have lost 17 of their last 23 games, are 1 1/2 games behind National League West division leader Arizona.
