“I gave it one last fight, unfortunately, my body wasn’t keeping up with my mind,” Gonzalez wrote on Instagram. “My heart and my mind are finally at peace with my decision.”

González, a South Florida native, pitched in 12 games last year for Chicago White Sox with four starts and had an ERA of 4.83. He has a career record of 131-101 with a 3.70 ERA in 13 seasons for four teams.

He was a two-time All-Star, with Oakland in 2011 and Washington in 2012. He also played for Milwaukee.

Gonzalez would have received a $1 million salary in the major leagues if he had been added to the 40-man roster.
