The Mets purchased the contract of infielder Danny Muno from Triple-A Las Vegas prior to Friday's game against Miami. New York optioned reliever Rafael Montero down to the Las Vegas to clear a spot on the roster for Muno.
Muno, 26, batted .235 in six minor-league games this season. Montero allowed an unearned run in two-thirds of an inning against the Marlins on Thursday. He owns a 4.15 ERA in 4 1/3 innings.
