Chicago Cubs legend Ryne Sandberg is battling prostate cancer.
Sandberg announced via his Instagram page on Monday that he was diagnosed last week with metastatic prostate cancer. He has already begun treatment for the issue.
Sandberg is 64 years old.
The Spokane, Wash. native made his MLB debut in 1981 with the Philadelphia Phillies, who quickly traded him to the Chicago Cubs. Sandberg then spent the entire rest of his career with the Cubs and became a franchise legend.
From 1982-97, Sandberg made 10 All-Star teams, won nine Gold Gloves at second base, and he was named the 1984 NL MVP.
Sandberg led the league in runs scored three times, triples once, and home runs once. He also stole 344 bases during his career, including a high mark of 54 in 1985.
Sandberg was inducted into the Baseball Hall of Fame in 2005, which was his third year on the ballot.
