Cordero had an opportunity to make the Montreal Expos roster on Opening Day in 1992, less than four years after he signed with the team at the age of sixteen, but he struck out 17 times in 38 spring training at bats, and was sent down to Triple-A Indianapolis.

He debuted with the Expos after the All-Star break and finished with a .314 batting average in 45 games, despite missing significant stretches of playing time due to a sprained ankle, a strained middle finger, and a serious case of chicken pox.

On July 27, the New York Mets signed Cordero to a minor league contract and assigned him to their Triple-A affiliate, the Norfolk Tides.

Following his playing career, Cordero has worked as a baseball coach during the summers at Kutsher's Sports Academy in Great Barrington, Massachusetts.
