Sammy Sosa had not been invited back to Wrigley Field, or anything Cubs-related, since he retired in 2007, but all that has changed.

It has long been speculated that Sosa took performance-enhancing drugs during his career, most notably during his home run binge in the late '90s.

Cubs ownership has long said Sosa would need to apologize and all but admit to taking steroids for the relationship to be mended.

On Wednesday, as the Cubs announced a festival for fans, Sosa admitted he "made mistakes."

"I left it all on the field for the Cubs and Cubs fans because I wanted to win and make the fans happy. I loved to see the fans at Wrigley in the Right Field Bleachers every home game," Sosa said in a letter. "I understand why some players in my era don't always get the recognition that our stats deserve. There were times I did whatever I could to recover from injuries in an effort to keep my strength up to perform over 162 games. I never broke any laws, but in hindsight, I made mistakes and I apologize.

"We accomplished great things as a team, and I worked extremely hard in the batting cage to become a great hitter. Cubs' fans are the best in the world, and I hope that fans, the Cubs and I can all come together again and move forward. We can't change the past, but the future is bright. In my heart, I have always been a Cub and I can't wait to see Cubs fans again."
