Just like in past years, the pink Mother's Day bats used in the game have been signed and are available for auction through MLB. As always, proceeds benefit the Susan G. Komen for the Cure. So, if you can swing it bid early and often.
A whole bunch are available including a boatload of Dodgers. Check out Russell Martin, James Loney, Charlie Haeger, Casey Blake, Reed Johnson, Ronnie Belliard, George Sherrill, Garrett Anderson and Matt Kemp. I expect more will be listed soon. See the entire list here.
Of special note, doesn't the Matt Kemp bat below look strange. It's definitely his bat, but that isn't his autograph. In fact, I'm sure that auto is Andre Ethier's. Maybe Andre has been using Matt's bat this season and that's why Andre has been on fire. He's been using the power of the Bison.
