Major League Baseball players Matt Cain, Mat Latos and Yovani Gallardo and their families have posed for the NOH8 Campaign, the silent protest which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

The NOH8 Campaign is helmed by photographer-activist Adam Bouska and his partner Jeff Parshley. The pair photograph celebrities and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

Cain, a pitcher for the San Francisco Giants, posed with his wife Chelsea, while Cincinnati Reds pitcher Latos appeared with his wife Dallas. And Milwaukee Brewers pitcher Gallardo was joined by his wife Patricia and their son Yovani Jr.

Recent athletes who have joined the NOH8 Campaign include NFL free agent C.J. Gable, New England Patriots safety Bret Lockett, NFL free ageint Nic Harris, former MLB player Billy Bean, former NFL player Esera Tuaolo and Portland Timbers defender Mike Chabala.

Bean and Tuaolo came out gay after retiring.
