Baseball Hall Famer Ryne Sandberg diagnosed prostate cancer

Baseball Hall of Famer Ryne Sandberg announced he is battling prostate cancer, asking for thoughts and prayers during his treatment.

Hall of Famer Ryne Sandberg, who spent 15 of his 16 major league baseball seasons with the Chicago Cubs, revealed on Monday that he is fighting prostate cancer.

Sandberg, 64, was inducted into the Hall of Fame in 2005 and shared the news on his Instagram account.

"Last week, I learned that I have been diagnosed with metastatic prostate cancer. I have begun treatment, and I am surrounded by my loving wife Margaret, our incredibly supportive family, the best medical care team, and our dear friends," Sandberg wrote. "We will continue to be positive, strong, and fight to beat this. Please keep us in your thoughts and prayers during this difficult time for me and my family."

Despite still having a residence in suburban Chicago, Sandberg remains involved with the Cubs as a team ambassador, according to The Athletic. The beloved second baseman, known as "Ryno," is a regular presence at Wrigley Field.

Sandberg was a 10-time All-Star in Chicago from 1982 to 1997, ESPN reported. He hit 282 home runs, had 344 stolen bases, and maintained a career batting average of .285, according to Baseball-Reference.com.

He was an 11-time Gold Glove Award winner and was named the National League's MVP in 1984, the season he led the Cubs to a division title, their first postseason appearance since the 1945 World Series.

"We cannot imagine how incredibly tough it is right now for Ryne and his family, but we do know Ryne is one tough competitor and a winner," Cubs senior vice president Julian Green told ESPN. "We are rallying around his family with locked arms as they begin their journey to conquer this battle with cancer."

Following his playing career, Sandberg managed the Philadelphia Phillies, where he compiled a record of 119-159 from 2013 to 2015, according to Baseball-Reference.com.

The Cubs expressed their support on social media, sending "love, strength, and support" to Sandberg and his family. "With locked arms, we are rallying around you and your family on the journey ahead to conquer this battle," the team wrote.
