Reynolds is expected to be called up prior to Tuesday's series opener against the Nationals, Adam Rubin of ESPN New York reports.
Reynolds hasn't put up overwhelming numbers with Triple-A Las Vegas, but the Mets don't have much infield depth after placing Wilmer Flores (hamstring) on the disabled list, so he seems primed to make his first appearance in the big leagues. The Mets will likely send a reliever to Triple-A to make room for Reynolds on the roster, but it's currently unknown who specifically will be demoted. Reynolds was selected over Ty Kelly and T.J. Rivera largely because he is already on the 40-man roster.
