CHICAGO -- Maybe it's a coincidence -- and if it is it's certainly a nice one -- but three of the four runs scored by the D-backs on a blustery Sunday afternoon came from players swinging pink bats.

Pink bats have become annual Mother's Day symbols as part of an overall "Going to Bat Against Breast Cancer" initiative by Major League Baseball that raises breast cancer awareness and directs massive proceeds to Susan G. Komen for the Cure.

Arizona catcher Miguel Montero not only used a pink bat, he also wore a pink chest protector and shin guards.

"Especially on Mother's Day, we want to support the people who have breast cancer and to help find a cure," said Montero, who doubled and scored a run in the fifth inning.

Both D-backs base coaches, Chip Hale and Lee Tinsley, wore pink wristbands, as did almost everyone in the starting lineup. Arizona manager Bob Melvin's lineup was posted on a pink card in the dugout.

D-backs starter Edgar Gonzalez showed his support by wearing a pink necklace.

Conor Jackson, who tripled and had two RBIs, has swung a pink bat each of the past two seasons.

"To raise money for a cause like that, it's a great feeling inside," he said.

Right fielder Justin Upton drove home a run in the fifth by not swinging his pink bat. The 20-year-old watched ball four go by with the bases loaded to give Arizona a 4-1 lead.

"It's for a good cause so we're excited to be able to help," Upton said. "For us to raise awareness about breast cancer and be able to help out with the drive to find a cure, it's great."

The players have done their part, and now it's up to fans to do theirs. Attention will move to the MLB.com Auction and the gradual arrival of those pink bats that were used and then signed, or just signed by entire teams.

Signed home plates and bases with the pink-ribbon logo also will be among the auction items that annually draw a frenzy, and all proceeds again will go to Komen. It is a "rolling auction," so if you don't see a player's bat in the next few weeks, keep coming back because eventually most or all of them show up there.

Fans also can purchase their own personalized "Mother's Day 2008" pink bats right now for $79 apiece at the MLB.com Shop, with $10 from the sale of each one going to Komen.
