San Francisco Giants manager Bruce Bochy voiced his concern to the media before the Giants' game against the San Diego Padres on Sunday afternoon about the negative effect that outside influences might have on his players.

From Andrew Baggarly, the Giants beat reporter for Comcast SportsNet BayArea:

Bochy "concerned" players like Melky Cabrera are getting bad advice from handlers. Undoing the work of MLB and clubs to educate about PEDs.

Bochy: "We can't follow these guys 24/7. It comes down to choices. These are grown men."

Bochy added that Giants do not allow any non-credentialed people in clubhouse, nor any supplement not approved by MLB.

Bochy's comments come in response to recent reports of Giants star outfielder Melky Cabrera's attempt to create a fake website to help him avoid a 50-game drug suspension.

The Giants are in first place in the NL West, but take a huge hit with the absence of Cabrera in their lineup. Prior to his suspension, the left fielder led his team in batting average and hits.
