Diamondbacks vs Mets Prediction

I don’t want to back the Mets as much as the next guy, especially in the favorite role. However, the Diamondbacks aren’t playing any better this week and Nelson has been a mess with a 6.61 ERA and 1.44 WHIP through 31.1 innings. As underachieving as the Mets are, McLean has been a bright spot with a 2.97 ERA and 0.94 WHIP through 39.1 innings. Through in 51 strikeouts and McLean looks like he can be an all-star in his second season. With the head and shoulders better pitcher on the mound, I’ll pinch my nose and side with the Mets.
