ST. LOUIS -- The Pirates mixed some pink into their black and gold on Sunday, joining all 30 clubs in wearing special uniforms and gear to celebrate Mother's Day.
This is the first year Major League Baseball implemented new uniforms and caps for Mother's Day. Throughout baseball, players and on-field personnel wore the symbolic pink ribbon for breast cancer awareness on their specially designed uniforms.
Chris Stewart, who had two RBIs, got in the spirit a day early, breaking in some Mother's Day-ready pink catcher's gear before Saturday's game. He put it on for Sunday's game, catching Gerrit Cole's strong six-inning start in a pink-and-gray chest protector and shinguards.
"I loved it. It wasn't too loud for me, which is good," Stewart said. "Mine was a little more subtle. It went well with the gray. I thought it was great."
Authentic game-used Louisville Slugger pink bats and other gear from Mother's Day games will be auctioned exclusively at MLB.com, with proceeds benefiting the fight against breast cancer. The complete Mother's Day collection -- which includes the special caps and jerseys being worn by players on Sunday -- is available at the MLB.com Shop.
