WASHINGTON — Former Giants outfielder Nate Schierholtz, an East Bay product who was part of the 2010 and 2012 World Series championship teams, has been suspended 80 games by Major League Baseball for violating its policy against using performance-enhancing drugs.

According to a news release, Schierholtz tested positive for ibutamren, “a growth hormone secretagogue and peformance-enhancing substance.”

Schierholtz his a minor-league free agent who has not played in the majors since 2014, with the Nationals. The San Ramon Valley High alum was drafted and developed by the Giants, who traded him to Philadelphia as part of the Hunter Pence deal.

After playing in Japan last year, Schierholtz, 32, signed a minor-league deal with the Tigers and played 31 games for their Triple-A Toledo, Ohio, affiliate.

His suspension takes effect if and when he signs with an organization.

“That’s a shame,” manager Bruce Bochy said. “I don’t have anything else to say about it. I feel bad these guys are still getting caught. These are pretty hefty suspensions these days.”
