Ricardo Rincón Espinoza (born April 13, 1970) is a Mexican former professional baseball relief pitcher.

Rincón played for several teams in Mexico before being signed by the Pittsburgh Pirates in 1997, breaking into the major leagues at the relatively advanced age of 27.

[1] Shortly after the Classic and five games into his Cardinal career, Rincón experienced shoulder pain and later underwent surgery to repair a torn labrum and rotator cuff.

He was loaned to the Mexico City Red Devils for the 2008 season, and was returned on August 28 and assigned to Triple-A New Orleans.

Teammate Mark Smith then hit a three-run walk-off home run in the bottom of the 10th to give Rincón the win.
