Jesse Sanchez of MLB.com reported the news on Colon, who won an American League Cy Young and made four All-Star teams during a 21-year MLB career that ended in 2018.
The Mexican League is a Triple-A league, but its teams are not affiliated with MLB clubs.
Colon's new team won the Mexican League title in 2019 and also recently added former MLB outfielder Rajai Davis, who is perhaps best known for his clutch eighth-inning home run in Game 7 of the 2016 World Series while playing for the Cleveland Indians.
As for Colon, the right-hander finished his big-league career with a 247-188 mark and a 4.12 ERA. Although he was hit hard by the end of his MLB career, which took place in his mid-40s, Colon did show impeccable control. Notably, Colon walked fewer than one batter per start from 2012-18.
The right-hander made two All-Star teams during that time, the last one being at age 43 with the New York Mets in 2016.
