Here we go again ... another MLB club hazing the rookies by making them hit an L.A. nightclub dressed as women. This time, it's the San Francisco Giants.
TMZ Sports has footage of rookie pitchers Derek Law and Albert Suarez at Hyde on the Sunset Strip -- in backless dresses with wigs.
The guys seemed to have fun doing it ... but the cross-dressing hazing has been under fire from certain LGBT orgs for a while which say the practice sends a dangerous message to kids.
In the past, everyone from the Oakland As to the Miami Marlins have taken part in cross-dressing hazing.
FYI, the NY Mets found a different way to haze their rookies last year -- sending them out dressed as male superheroes in full costume.
