Wilmer Flores is expected to be promoted from Triple-A Las Vegas, taking the roster spot that had belonged to Omar Quintanilla. How Terry Collins plans to divvy the playing time at shortstop remains to be seen, but clearly the Mets are dissatisfied with their production at shortstop and Ruben Tejada's playing time will diminish. Of course, how Flores will handle the big-league speed of the game at shortstop remains to be seen. There are many skeptics. The Mets abandoned using Flores at shortstop in the minors after the 2011 season, only to reinstate him at the position this season after he spent eight weeks at agility camp. The move, though, appeared primarily out of desperation for options. ESPN Stats & Information's Mark Simon computed early Wednesday that Mets opponents have a .278 batting average on groundballs -- highest in MLB. That's undoubtedly attributable in some substantial part to a lack of infield range. Adding Flores may be a further drag.
