The New York Mets stay in Phoenix on Saturday, May 9, 2026, for the second game of their weekend series against the Arizona Diamondbacks at Chase Field. First pitch is set for 7:15 PM ET, with New York trying to build off a 3-1 extra-inning win in Friday’s opener.
The Mets enter at 15-23, which still looks rough on the surface, but they have won four of their last five and finally have some road-trip momentum. Arizona is 17-20 and sliding again, with the Diamondbacks losing the opener despite getting a strong start from Ryne Nelson and another quiet offensive night from the lineup.
The pitching matchup is the whole handicap here. Clay Holmes brings a 4-2 record and 1.69 ERA into this start for New York, while Merrill Kelly enters at 1-3 with a 9.95 ERA for Arizona. The Mets are only a slight road favorite, so this number is basically asking whether bettors trust New York’s inconsistent lineup enough to take advantage of a clear starting-pitcher edge.

New York Mets Betting Form
New York is not suddenly fixed, but the Mets are playing their best baseball in a while. Friday’s win was not an offensive explosion, yet it did show some late-game toughness. Mark Vientos homered and drove in the go-ahead run in extras, Carson Benge delivered again after moving up in the order, and the bullpen protected the lead without turning the bottom of the 10th into a mess.
The broader New York Mets stats and results still show a team that has struggled to turn talent into steady scoring. Juan Soto is the main lineup anchor, Vientos has real power, and Francisco Alvarez gives them another right-handed threat, but the depth is still uneven. Francisco Lindor’s hand status is also worth monitoring because this lineup gets thinner fast when he is unavailable.
Holmes is the reason New York deserves favorite status. He is not a huge strikeout arm in the traditional ace mold, but the run prevention has been excellent. His sinker-heavy profile keeps the ball on the ground, his WHIP is under 1.00, and he has worked deep enough lately to protect the Mets from needing a full bullpen game. That points toward Mets moneyline, Mets first 5, and maybe Arizona team total Under if the number is fair.
Arizona Diamondbacks Betting Form
Arizona is in a bad offensive stretch, and Friday made it look even worse. The Diamondbacks scored once, went quiet with runners on, and wasted a strong pitching performance. That has been the frustrating part. They still have bats that look dangerous on paper, but the timely hitting has not been there often enough.
The Arizona Diamondbacks schedule and stats point to a team with more upside than its recent form, especially at home. Corbin Carroll is still the key pressure bat, Ketel Marte can change an inning quickly, Ildemaro Vargas has been productive, and Nolan Arenado showed power in the opener. But Arizona needs more than solo shots. They need traffic, walks, and better at-bats with runners in scoring position.
Kelly is the concern. His 9.95 ERA and 2.32 WHIP are not small-sample noise you can just ignore, especially with 15 walks in 19 innings. He still has experience, command history, and enough pitch mix to get through a lineup if he locates early. But right now, bettors are being asked to trust a starter who has been putting too many men on base and giving up too much damage when behind in counts.
New York Mets vs Arizona Diamondbacks Matchup Breakdown
The starting pitcher edge clearly belongs to New York. Holmes has been the more stable arm by a wide margin, while Kelly is still searching for command and rhythm. If Holmes gets six innings with limited traffic, the Mets become very live to win a lower-margin road game without needing their lineup to go crazy.
Arizona’s case is more about home field, contact quality, and New York’s offensive inconsistency. The Mets are still not a lineup I want to blindly trust as road chalk. They can go quiet for long stretches, and if Kelly somehow gets through the first three innings clean, the market edge shrinks a bit. That is the hesitation.
Chase Field can play differently depending on roof and conditions, but the scoring environment is still friendly enough when pitchers miss spots. With Kelly struggling, the Mets should have chances to create early traffic. If Arizona gets to Holmes, it probably comes through Carroll, Marte, Vargas, or Arenado turning one mistake into quick damage.
This is a good example of why pitcher reputation and current form need to be separated. Kelly has the longer track record, but Holmes owns the current edge. The MLB betting guide is useful for matchups like this because the number is not just about records. It is about starter form, lineup health, bullpen path, and how much the market has already priced in.
New York Mets vs Arizona Diamondbacks Predictions and Best Bets
I lean Mets moneyline. It is not the most comfortable thing to back a 15-23 team on the road, but the price is fair because the pitching matchup is so lopsided. Holmes has been reliable enough to trust, and Kelly’s current command issues create too much early-inning risk for Arizona.
The run line is tempting at +140. I get it. If Kelly walks hitters again and New York gets even one extra-base hit with men on, this can open up quickly. Still, the Mets have not been consistent enough offensively for me to make the run line the main play. A 4-3 or 5-4 Mets win is very possible, and that would burn the more aggressive ticket.
The total is more complicated. Over 9.0 makes sense if you are fading Kelly hard, especially with both bullpens coming off extra innings Friday. But Holmes can suppress Arizona enough to keep the game from fully taking off. I would rather isolate the Mets side than chase a full-game Over that needs Arizona to contribute.
First 5 Mets moneyline is also interesting because it leans fully into the Holmes over Kelly angle and reduces some bullpen volatility. But with the full-game moneyline still near a short favorite price, I prefer keeping the late innings on my side. New York has the better starter, the better recent form, and enough bats to cash this number.
Best Bet: Mets Moneyline -116.
