The Mets (22-13) are off a crushing doubleheader loss to the St. Louis Cardinals after sweeping them 4-0 earlier in April.

In April, the Mets were beginning their 7-game winning streak and had gained significant momentum for the start of the 2025 MLB season. However, as we start May, the New York Mets have lost a little bit of that luster, going 4-6 in their last ten, with 2 of those losses coming from the Arizona Diamondbacks (18-16).

Tonight, the Mets take on the Diamondbacks in Phoenix, where they hope to swing and pitch themselves out of this rut. 

The New York Mets will start the excellent RHP, Griffin Canning (2.61 ERA), opposite the Arizona Diamondbacks' RHP start, Ryne Nelson (5.82 ERA). Canning is poised to give the Mets a solid performance. But the Mets' bullpen will have to show up tonight and perform as they did just one month ago to win.

Who’s Winning the Mets vs. Diamondbacks Series?

From a statistical standpoint, the Mets are the better team. The Mets should beat the Diamondbacks tonight and take this series. However, and this has been a continuous issue with the Mets' morale, when the Mets start winning, they start winning. We'll see dominant streaks and clutch performances across the roster. But when they start losing, they really lose. The demoralization of the roster is contagious. 

One solid win is all it takes for the Mets to ignite another winning streak.
