Nothing new here but..... ] BY JON HEYMAN Newsday Staff Writer May 30, 2006, 1:32 PM EDT Mets prospect Lastings Milledge has been promoted and will make his Major League debut tonight, the team announced this afternoon. Milledge, a rare combination of speed and power who's considered the team's top prospect, takes the place of rightfielder Xavier Nady, who had an appendectomy after Monday's game against the Diamondbacks. Nady, who's also suffered from back spasm recently, is being placed on the 15-day disabled list. Milledge will play in his place. The Mets have said they wouldn't call him up to sit him on the bench. Milledge, 21, was batting .291 with four homers and 19 RBI at Triple-A Norfolk. He had four home runs and 19 RBIs in 182 at-bats. He also stole eight bases. Milledge was the Mets' No. 1 pick in the 2003 amateur draft.
