Arizona Diamondbacks vs New York Mets Prediction
The New York Mets are favored against the Arizona Diamondbacks due to a substantial advantage in starting pitching, with Nolan McLean poised against a struggling Merrill Kelly. Despite the Mets' significant injury list, their recent offensive uptick and the Diamondbacks' current slump reinforce the prediction for an away win.
Arizona Diamondbacks host New York Mets on Tuesday, part of the 2026 MLB season. Both teams' season records, recent form, and matchup-specific factors are detailed in the stats and prediction sections below.
ATS PREDICTION
New York Mets Win
Predicted: 6-2
โก66%
The New York Mets hold a significant pitching advantage with Nolan McLean (1-2, 2.97 ERA, 0.94 WHIP) projected to start, facing Merrill Kelly (1-3, 9.95 ERA, 2.32 WHIP), whose home ERA escalates to 14.40. While the Mets have several key offensive players on the injured list, their recent form shows they've won four of their last six games and are hitting for power with 11 home runs and a .384 slugging percentage over their last 10 contests. In contrast, the Arizona Diamondbacks, despite a better overall record, have struggled recently, losing six of their last seven games and batting just .195 with 6.3 hits per game in their last ten outings. This pronounced pitching mismatch, coupled with the Mets' recent offensive spark, strongly favors an away victory.
SPREAD PREDICTION
New York Mets -1.5 (-1.5)
71%
Given the stark difference in starting pitching with Nolan McLean's strong performance against Merrill Kelly's struggles, particularly at home, the Mets are well-positioned to win by more than one run. The Diamondbacks' recent offensive slump further supports the Mets covering the -1.5 spread, as a projected score of 6-2 would easily satisfy this margin.
TOTAL PREDICTION
Under 8.5
71%
Despite Merrill Kelly's high ERA, Nolan McLean's impressive 2.97 ERA and 0.94 WHIP suggest he will limit the Diamondbacks' scoring. The Mets' offense, while showing recent power, is still impacted by significant injuries to key players like Francisco Lindor and Jorge Polanco, which could keep their total runs in check even against a struggling pitcher. Therefore, a lower-scoring game, falling under the 8.5 total, is a reasonable expectation.

Arizona Diamondbacks Team Total
Under 3.5 Runs
Nolan McLean's excellent season stats (2.97 ERA, 0.94 WHIP) and the Diamondbacks' recent offensive slump (batting .195 in last 10 games) make it difficult for Arizona to score more than three runs.

โ Moneyline: New York Mets
The significant pitching mismatch favoring McLean over Kelly, combined with the Mets' recent winning streak, suggests their true win probability is higher than the implied odds of 54.1%.
โ Run Line: New York Mets -1.5

โ Total Runs: Under 8.5
