ST.LOUIS -- If Jackie Robinson Day was any indication, Cardinals players love to get involved in a good cause. Several Cardinals will be at it again on Mother's Day.

A number of Major League players will help raise awareness for breast cancer on Mother's Day, May 13, by using pink Louisville Slugger bats. To date, more than 200 players have signed up to use a pink bat, which is more than twice the participation in 2006.

Select game-used bats, as well as team-autographed bats from every club, will be auctioned on MLB.com at a later date, with proceeds benefiting Susan G. Komen for the Cure.

Fans can also purchase their own personalized pink bat at MLB.com, or www.slugger.com, with Major League Baseball donating $10 from the sale of each bat to benefit Susan G. Komen for the Cure.

After the entire team sported No. 42 jerseys for Robinson, eight Cardinals players signed up to support the Komen Foundation and will join in on the league-wide celebration.

The Cardinals who are tentatively planning to participate are Adam Kennedy, David Eckstein, Albert Pujols, Yadier Molina, Scott Rolen, Jim Edmonds and Skip Schumaker. Outfielder Preston Wilson had also signed up to join in, but is currently on the 15-day disabled list.

Edmonds used the pink bat last year and registered a three-hit game with it. He said he was looking forward to using it again.

"I had some pretty good luck last year with it," Edmonds said. "I was happy to do it since it's for such a good cause."

Molina was the only Cardinal to receive his bat so far, because he uses a different style bat than the others. Clubhouse manager Rip Rowan said he was expecting the other bats to come in soon, and would distribute them before the club's West Coast road trip. Kennedy sported the pink bat last year as a member of the Angels and said he was happy to participate again like Edmonds.

The Susan G. Komen Foundation started in 1982 and has become the largest source of nonprofit funds dedicated to the fight against breast cancer.

There will be a number of tributes to the foundation on the field. Players will sport pink wristbands and pink ribbons will be displayed on player uniforms and by all on-field personnel. There will also be pink ribbon logos on the bases and commemorative home plates, along with pink dugout lineup cards.

Team-autographed commemorative memorabilia will be auctioned off on MLB.com, and the proceeds will benefit the Komen Foundation.

Major League Baseball supports a number of health initiatives. Other projects include the Father's Day Prostate Cancer Foundation Home Run Challenge and Play Smart When it Comes to the Sun, which supports skin cancer awareness.
