Two pitchers who have yet to give bettors a reason to worry, a total that has already moved a full half-run since opening, and a series that has swung wildly from a 10-inning thriller to a 7-2 blowout in back-to-back days — Thursday's series finale between Arizona and New York is one of the more textured betting spots on the MLB picks board. The Mets bring a stronger overall profile into this game on both sides of the ball, the public has been hammering New York across every morning snapshot, and the case for the under has been building since the line opened at 7.5. Here is why the smart money is leaning toward a controlled final that ends with the Mets winning by two.

Diamondbacks vs Mets Key Matchups and Handicap
Arizona
The Diamondbacks enter Thursday's series finale having split the first two games in dramatic fashion — a 4-3 loss in 10 innings on April 7 followed by a commanding 7-2 win on April 8. That bounce-back performance deserves credit, but in the context of a three-game series against a deeper opponent, it functions more as a reset than a momentum shift. Arizona is 3-2 over its last five games, which is a respectable recent record, but the underlying numbers across the full early-season sample reveal a team that has been outperformed in almost every major offensive and pitching category by the club standing across the diamond on Thursday.
The Diamondbacks are hitting .223 with 45 runs, 85 hits, eight homers, a .284 OBP, and a .367 slugging percentage — numbers that rank in the bottom half of the National League and reflect a lineup that has yet to find consistent production beyond its top contributors. Corbin Carroll is carrying an enormous portion of Arizona's offensive load, batting .333 with two home runs, 11 RBI, a .408 OBP, and a .690 slugging percentage that makes him the most dangerous bat in this entire matchup. The problem is that when Carroll is neutralized or the lineup around him goes cold, there is very little behind him to compensate. The injury list amplifies that concern significantly — Pavin Smith, Carlos Santana, Lourdes Gurriel Jr., and Tyler Locklear are all unavailable, stripping the Diamondbacks of multiple regular lineup options and forcing the team to rely on depth players in key spots against one of the better pitching staffs they will face this week.
NY Mets
New York brings the more complete roster into Thursday's finale and has the statistical profile to back up the market's consistent preference for the Mets across every line movement snapshot since Tuesday afternoon. The Mets are hitting .248 with 55 runs, 105 hits, nine home runs, a .324 OBP, and a .370 slugging percentage — all materially better than Arizona's numbers — and the team has been particularly productive over the last five games, scoring 34 runs across that stretch including four games with at least four runs scored. That kind of lineup consistency against a shorthanded Diamondbacks rotation is one of the primary drivers of the Mets' run-line value.
The pitching profile is even more compelling. New York enters with a 2.90 team ERA and 1.20 WHIP, and the Mets have compiled 110 strikeouts compared with 81 for Arizona — a staff that is both limiting runs and controlling at-bats at a higher rate. Eduardo Rodriguez takes the mound yet to allow an earned run across 12.0 innings with a 0.92 WHIP, which is one of the cleaner early-season starting lines in the National League. The offense features Francisco Alvarez with three home runs, Luis Robert Jr. hitting .333 with a .478 OBP, and Marcus Semien already driving in six runs. The biggest absence is Juan Soto, who will not return until at least April 21, and the Mets are also without Nate Lavender, Brandon Waddell, A.J. Minter, and Mike Tauchman — a meaningful cluster of bullpen and bench losses. But the starting lineup is deep enough to absorb those absences, and Rodriguez's effectiveness makes the bullpen burden manageable for most of this game.
Betting Trends — ARI and NYM
- The Mets' moneyline has held steady at -163 throughout most of the tracking window, with brief spikes to -171 and -168 reflecting sharp action absorbed by books before settling back — a pattern that suggests the market is comfortable with New York as the correct favorite but not willing to push the price significantly higher.
- New York drew 100% of both tickets and dollars at the two earliest Thursday morning snapshots, a unanimous signal that carried the line briefly to -168 before books rebalanced back to -163 — a sign that sharp action was absorbed rather than driving sustained movement.
- By mid-morning, the Mets continued drawing 68-85% of tickets and 81-85% of dollars across multiple snapshots, confirming a sustained public and sharp lean toward New York that has been consistent since the line first posted Tuesday afternoon.
- The total has undergone the most significant structural change in this matchup, dropping a full half-run from 7.5 at opening to 7, driven by heavy under-side pressure that pushed the juice from -115 on the under at open to -131 before the number moved down to 7 — a textbook under-driving line move.
- Arizona's lineup is missing four regular position players in Smith, Santana, Gurriel Jr., and Locklear, which substantially reduces the Diamondbacks' ability to generate the kind of multi-inning offensive output needed to push this game over a total of 7.
- Both starters have early-season ERAs under 3.00 and WHIPs under 1.00, which is one of the more pitcher-favorable matchup profiles on the Thursday slate and reinforces the under as the sharper total play regardless of which team wins the game outright.
Key Injuries and Notes — ARI and NYM
- Pavin Smith (ARI, 1B) — Out: Smith is unavailable for Thursday's game, removing a regular lineup presence from Arizona's first-base depth.
- Carlos Santana (ARI, 1B/DH) — Out: Santana's absence further thins Arizona's lineup options and reduces the Diamondbacks' run-producing depth behind Corbin Carroll.
- Lourdes Gurriel Jr. (ARI, OF) — Out: Gurriel is unavailable, limiting Arizona's outfield options and left-handed bat depth in the lineup.
- Tyler Locklear (ARI, INF) — Out: Locklear is also missing, leaving the Diamondbacks short of infield depth options and further compressing a lineup already leaning heavily on Carroll.
- Merrill Kelly (ARI, SP) — Out: Kelly's absence from the pitching staff limits Arizona's rotation depth and overall roster flexibility heading into a game where bullpen usage may be a factor.
- Juan Soto (NYM, OF) — Out through April 21: Soto is the most impactful single name missing from either roster. His absence removes New York's most dangerous offensive presence, though the Mets' lineup depth has been sufficient to compensate through the early-season sample.
- Nate Lavender, Brandon Waddell, A.J. Minter (NYM, RP) — Out: Three bullpen pieces are unavailable for New York, which increases Rodriguez's importance as a deep-innings starter on Thursday and adds some late-game risk if the Mets need to navigate a tight situation in the seventh inning or later.
- Mike Tauchman (NYM, OF) — Out: Tauchman is also unavailable, limiting New York's outfield bench depth for Thursday's finale.
Diamondbacks vs Mets ATS and Total Picks
- Run Line: Mets -1.5 — New York's superior team ERA, deeper lineup, and the quality of Rodriguez on the mound make laying 1.5 runs a justified play in a matchup where the projected final is 4-2. Arizona's missing position players further reduce the Diamondbacks' ability to generate the late offense needed to keep the margin within one.
- Total: Under 7 — The total moved a full half-run from 7.5 to 7 on sustained under pressure, and the structure of this game supports that move entirely. Two starters with sub-3.00 ERAs and sub-1.00 WHIPs, Arizona missing four lineup regulars, and New York's bullpen limitations all point toward a tightly managed game where seven runs combined is a ceiling rather than a floor.
- Moneyline: Mets -163 — The Mets have drawn 68-100% of money across every available snapshot, the team stats support New York as the clear favorite, and Rodriguez's early-season performance gives the Mets one of the most trustworthy starting pitcher edges on the Thursday slate.
Final Score Prediction
Mets 4, Diamondbacks 2
Rodriguez controls the game through six innings, Carroll provides Arizona's only genuine threat with a homer or extra-base hit that makes it interesting briefly in the middle frames, but the Diamondbacks' depleted lineup cannot sustain enough traffic to overcome the deficit. New York's offense builds runs gradually against McLean rather than in a single explosive inning, and the Mets' bullpen — despite its absences — holds enough to close out the cover and keep the final well under the total.
How to Bet This Game
The Diamondbacks-Mets series finale is a clean betting spot with well-defined angles on both the run line and the total — and the line movement story is one of the more instructive of the day for bettors who want to understand how sharp money works before first pitch. Here is how to approach it.
For bettors who want to study how a total drops a full half-run from 7.5 to 7 on under pressure without a corresponding move in the moneyline, social sportsbooks provide a no-risk environment to track exactly this kind of pre-game movement. This matchup is a textbook example of books adjusting the number rather than the juice — a lesson that takes real money to learn the hard way, or virtual currency to understand safely first.
For the Mets run line at -1.5, locking in the price before any additional public money arrives and potentially moves the number is the priority. New York has drawn 100% of both tickets and dollars at multiple snapshots, and the run line is one of the cleaner plays on the slate given Rodriguez's form and Arizona's roster attrition. The bet365 bonus code gives new users a boosted entry position on exactly this type of single-game run line play, making it one of the better platforms to lock in the Mets before game time.
For the under at 7, getting in at -108 rather than the -115 or heavier juice that accompanied the original 7.5 total is a meaningful improvement in value. Two dominant starters, a depleted Arizona lineup, and New York's bullpen managing a modest lead all support a final well under the number. The fliff promo code is a great option for new users who want to act on this under play with bonus currency before committing to full-stake wagering on one of Thursday's most compelling total setups.
