The 57-year-old former player and coach revealed his diagnosis on Tuesday by releasing a statement.

"I have faced many different obstacles in my life, and have always maintained a strong belief that no matter the circumstances, I could overcome those obstacles. While this diagnosis poses a new kind of challenge for me, I intend to stay true to my beliefs. With the support of my family and friends, I will meet this challenge with the same determination and unwavering intensity that I have displayed in all of my endeavors in life. I look forward to being back at the ballpark as soon as possible."
