Robertson and Brooks Raley are viewed as the primary options for saves for the Mets while Edwin Diaz (knee) is sidelined, Andy Martino of SNY.tv reports.

EDGE Analysis

Official word on Diaz won't be available until sometime after his MRI on Thursday, but the Mets are bracing for their star closer to be out for a significant period of time. Robertson would be a natural choice to slide into the ninth inning, having saved 20 games while posting a 2.40 ERA over 58 appearances for the Cubs and Phillies last season. He and Raley are both worthy of being selected in fantasy leagues -- pending news on Diaz -- with Robertson probably the favorite.
