New York Mets vs Arizona Diamondbacks Prediction


The Mets are slowly but surely starting to put some wins together and walk-off wins like last night only add to the confidence. The Diamondbacks can’t get out of their own way. Holmes has been ridiculous through 42.2 innings with a 1.69 ERA and 0.98 WHIP. Kelly has been awful with a 9.95 ERA and 2.32 WHIP through 19 innings. We’re not to the point where you can back the Mets with high confidence, but this is a spot they should win again. I’ll gladly take the Mets at this soft price.
