For years, professional athletes in several sports have worn and used pink gear in honor of Breast Cancer Awareness. But what Major League Baseball is doing this weekend may be a first.

Baseball clubs will be using balls with pink stitching on Mothers Day as part of the league's annual Breast Cancer Awareness campaign. This will go along with pink bats, gloves, cleats and more.

In addition to the balls, each club will have an honorary bat girl who is a breast cancer survivor.
