Since then, the Crowleys, together with the A's, have been helping Kaki Saxon Moyce, 56, and others like her keep up the fight.
On Saturday, Oakland held its 10th annual Breast Cancer Awareness Day. Moyce was on hand to throw out the ceremonial first pitch along with 500 other survivors clad in pink jerseys who formed a huge human ribbon on the field before the game.
Players from the A's and the Rangers took the field wearing pink sweat bands and ribbons on their jerseys in a tribute to those battling breast cancer.
"My younger sister and my mother both died of breast cancer," Moyce said. "I'm a breast cancer survivor. This is the 10-year anniversary. It's absolutely huge, and I'm honored to be here. It's an absolutely wonderful celebration of survivorship."
The A's announced the latest edition of Breast Cancer Awareness Day raised $116,750 to benefit the American Cancer Society and the Northern California Cancer Center. Since its inception, the club has raised more than $1 million to help raise awareness and advance medical research.
"For them to support this is awesome," said A's pitcher Kirk Saarloos, who caught Moyce's ceremonial pitch. "Cancer is a big deal in this country and all over the world, and the best way to try to control it -- we haven't found a cure -- is [to] raise awareness and money and have people go out and get checked to try to catch it early."
Saarloos has a personal stake in the fight against cancer as well. His mother has fended off bouts of colon and breast cancer in the past two years.
"It's a tough deal," Saarloos said. "She caught it early, and she's had a 100-percent clean bill of health right now. She's doing great. But today is a big deal, and it is a special day for me and my family. It's something I never forget."
