Players and on-field personnel also wore the symbolic pink ribbon on their uniforms, as well as pink wrist bands, batting gloves and arm sleeves.
The colorful gear was designed to raise awareness for breast cancer on Mother's Day, and the pink bats used in games will be signed by teams, authenticated by MLB and presented exclusively at the MLB.com Auction site. They'll raise money for the Susan G. Komen Breast Cancer Foundation.
"It's definitely a good thing any time you can raise awareness for something like this," Davis said. "And it's kind of a cool thing for us, because obviously a bunch of us don't get to see our wives or our moms on Mother's Day so we kind of let them know that we're thinking about them with the pink bats, pink wrist bands and all that stuff. So it's all definitely a positive thing."
Davis, who hit a home run in his first at-bat using the pink lumber, joked he may ask for permission to use it the rest of the year.
