This cancer survivor collects autographs from the Athletics on her prosthetic arm

On Wednesday night at Marlins Park, Kristin Mello asked members of the Oakland A's for autographs. Trevor Plouffe , Khris Davis , Yonder Alonso and Liam Hendriks all signed their names on her left arm. Brad Ziegler , a former member of the Athletics, now playing for Marlins, also added his signature to the collection.

The autographs will likely stand the test of time, too -- because they're written in silver ink on her prosthetic arm.

Mello, 25, was diagnosed with epithelioid sarcoma last year, which resulted in a below-the-elbow amputation of her left arm. This week, she was in Florida participating in a research study that involved prosthetics and had some time off. So, she decided to take in a game on the road to watch her favorite team play.

"For years, I had been dealing with problems in my left hand," Mello told MLB.com. "In the beginning of 2009, I first noticed my left pinky finger curling and being numb. I went to the doctors because it was not normal and I had not injured myself."

After some tests, the doctors thought it was an issue with her ulnar nerve and decided to pursue surgery later that same year.

"However," she said, "that surgery ended up flattening my nerve completely, and as a result I lost some of the muscle mass in my left hand."

Fast forward to 2014, her hand was still causing her issues. Once, when she was out with some friends, she injured her wrist; while she didn't think much of it, her wrist had some discoloration and grew to the size of a golf ball.

MRI's had shown a tiny growth in what appeared to be scar tissue in her wrist.

On May 10, 2016, they fused Mello's fingers and performed a biopsy. Two days later, she was told to come back -- that was when they broke the news she had been diagnosed with epithelioid sarcoma. They described it to her as "a very rare soft tissue sarcoma that is incredibly aggressive once it metastases." The doctors informed her chemotherapy and radiation have little to no effect on epithelioid sarcoma, so amputation was the best route to go to "prevent the possible spread of ES to [her] lymph nodes and lungs."

Nevertheless, she had one of the most memorable nights of her life on May 19, when she and her family attended an A's game. It was the night before she had the amputation in her left arm.
