A native of Thousand Oaks, Calif., Yelich actually has played in his home state the past two Mother's Days. On each occasion, his mother, Alecia, was at the park.
In 2014 at San Diego, Yelich homered with a pink bat, giving the day even more meaning.
"I think it's cool," Yelich said after the Marlins' 3-2 loss to the Giants. "It's always nice to play in front of your family, especially having your mom there on Mother's Day. It happened last year, too, which was cool."
Yelich was the only Marlins player to use a pink bat Sunday. A number of players sported pink wristbands featuring the symbolic breast cancer ribbon, pink undershirts and pink-trimmed shoes.
Going to Bat Against Breast Cancer is a Major League Baseball initiative supported by MLB charitable partners Stand Up To Cancer and Susan G. Komen. This initiative raises awareness about the breast cancer cause and also raises funds to support breast cancer research.
