Seattle Mariners 2015 Honorary Bat Girl winner

Kathleen Sutton of Mill Creek will be recognized on Sunday, May 10, as part of MLB's "Going to Bat Against Breast Cancer" Program

A new mom of a five-and-a-half month old baby, who is undergoing treatment for Stage 4 breast cancer, is the Seattle Mariners 2015 Honorary Bat Girl.

Kathleen Sutton of Mill Creek will throw out the ceremonial first pitch before the Mariners play the Oakland Athletics on Sunday, May 10, at Safeco Field.

While pregnant, Sutton noticed something unusual with her breast. After a little research she ignored it as a natural change in her body. A few months later, recurring pain made her realize something was wrong and she decided to have it checked. That was October 8, 2014. The diagnosis was inflammatory breast cancer, a rare and aggressive form of cancer. Before she could start chemotherapy, an ultrasound to check on her unborn baby showed that the cancer had spread to her liver. It was Stage 4, which is considered incurable.

Sutton had one round of chemo therapy while pregnant and on November 18, she gave birth to a healthy baby boy she and her husband Mike named Spencer. One week later, Sutton underwent surgery and a battery of tests that showed the cancer had spread not only to her liver but to her bones, too.

Since then, Sutton has undergone weekly chemotherapy treatments with baby Spencer in tow. "He comes with me. We hang out. He takes a nap and I watch TV," said Sutton.

Although Sutton is nervous about throwing out the ceremonial first pitch before the game, she hopes to raise awareness of her rare cancer.

"If I had heard about inflammatory breast cancer and its symptoms before, I would have gotten it checked out sooner and caught it before it became Stage 4. Everyone thinks breast cancer and thinks to look for lumps, but there are no lumps with inflammatory breast cancer, and no one has heard of it or knows its symptoms so they don't think to look for it."

Sutton credits her husband Mike with helping her through this emotional ordeal, calling him "my rock." Despite the chemo, Sutton has gone back to work baking wedding cakes for the Lake Union Café Custom Bakery. Her husband, her son, and her work are helping Sutton maintaining a positive outlook.

"I'd like to let people know that because you have an incurable disease doesn't mean you have to stop living. You don't have to be a 'Debbie Downer.' You can still be you and live your life," said Sutton.

Major League Baseball introduced the Honorary Bat Girl program in 2009 to raise additional awareness and support for the annual "Going to Bat Against Breast Cancer" initiative celebrated on Mother's Day. In seven years, thousands of unique testimonials have been submitted and more than two million fan votes have been cast. Going to Bat Against Breast Cancer is a Major League Baseball initiative supported by MLB charitable partners Stand Up To Cancer and Susan G. Komen. This initiative raises awareness about the breast cancer cause, while also raising funds to support breast cancer research.

On Mother's Day, Mariners and Athletics players and on-field personnel will wear the symbolic pink ribbon on their uniforms along with pink wrist bands. Commemorative base jewels and dugout lineup cards also will be pink. Games will feature a pink-stitched Rawlings baseball, the official ball of MLB, as the official game ball. Many MLB players also will use pink bats, and pink Louisville Slugger bats, the Official Bat of Major League Baseball, will be stamped with the MLB breast cancer awareness logo. Many authenticated, game-used Louisville Slugger pink bats from Mother's Day games will be auctioned exclusively on to benefit the fight against breast cancer.
