The bitter feud between Sammy Sosa and the Chicago Cubs is over -- the two sides are making amends after the MLB legend finally fessed up to making "mistakes" during his career.
Sosa was essentially outlawed by his former employer after he retired from the league in 2007 ... with the main gripe believed to be the fact he never admitted to, or apologized for, using performance-enhancing drugs, which he tested positive for in 2003.
That all changed on Thursday ... when the 56-year-old released a statement owning up to his past.
