The Rockies are averaging two runs a game during their last four games. Their offense is far worse away from Coors Field. The Pirates have a bottom-five offense. They are averaging a puny 1.5 runs during their past eight games.

Seeing that Doug Eddings is slated to be the home plate umpire cements this Under play. The Under has cashed at 58 percent during the last five years when Eddings has been behind the plate. He's extremely pitcher-friendly with his strike zone.

This should be of help to the Rockies' Ryan Feltner, who shut out the Marlins for eight plus innings in his last start before faltering in the ninth inning.

Pirates starter Bailey Falter had a tremendous April allowing only four runs in four starts.
