The Mets have called up their top prospect, outfielder Fernando Martinez. Jose Reyes was placed on the disabled list, retroactive to May 21, with right calf pain. The major league debut of Martinez will be greeted with anticipation by Mets fans. Scouting reports rave about the 20-year-old's multi-tool game featuring power, average, speed, glove and arm. The Mets also announced that they have acquired minor league shortstop Wilson Valdez from the Cleveland Indians for cash considerations.
