For the 6th year, Susan G. Komen for the Cure and Major League Baseball are Going to Bat Against Breast Cancer.
Major League Baseball players, coaches and umpires will wear pink wristbands and pink ribbon decals on Mother’s Day, May 9th. Louisville Slugger has produced and donated pink bats that hundreds of players will also be using on that day.
Once again, much of the memorabilia worn in games across both leagues will be auctioned at MLB.com, with proceeds going to Komen for the Cure.
For collectors, the biggest attractions are the pink bats that many players use at least once in the game. Those used by a popular player or those that play a pivotal role in a game often sell for hundreds or even thousands of dollars.
