The Mets (3-3) continue their road trip tonight, starting a 4-game series at San Francisco (2-4). First pitch is set for 9:45 pm, ET. You can catch the game on MLB.TV as part of the Fubo TV package.
Runs should be at a premium.
Robbie Ray (0-1, 3.38 ERA) goes for the Giants, opposite Mets starter David Peterson (0-0, 0.00). Ray was a tough-luck loser in his opening start — allowing just 2 ER in a 3-0 loss to the Yankees. Peterson scattered 6 hits in 5.1 innings in his opening start vs. Pittsburgh.
We dive into the top betting markets, analyze the offensive and pitching dynamics of both clubs, and uncover the sharpest angles to help you handicap tonight’s Mets at Giants game.
Looking at the opening market numbers paints an intriguing picture of how betting action has shaped this matchup. The runline originally opened with New York at -1.5 (+134) and San Francisco at +1.5 (-162). Since then, the juice on the home team getting a run and a half has swelled to -166. This line movement corresponds directly with a steady stream of runline bets favoring the underdog, likely driven by sharp respect for Robbie Ray’s 0.94 WHIP.
The game total has also experienced a fascinating shift. Oddsmakers opened the total at 7.5 with the Over favored at -114 and the Under at -106. However, heavy market action has entirely flipped the juice, now pricing the Under as the favored outcome at -112.

Expert Mets vs Giants Predictions & Props
Diving into the statistical profiles for both clubs reveals clear advantages we can leverage in the betting markets. The underlying metrics and performance data paint a vivid picture of what to expect at Oracle Park, backed by situational trends that cannot be ignored. Entering tonight, unders are a perfect 6-0 (100%) in Mets games, signaling a massive trend of low-scoring affairs. Furthermore, the Giants are hitting a collective .201 as a team, struggling mightily to generate run-scoring opportunities.
New York is currently showcasing superior plate discipline and elite run prevention. The away dugout boasts a .313 on-base percentage and a .648 OPS, pacing well ahead of San Francisco’s sluggish .264 OBP and .558 OPS.
The Pick: Mets Moneyline ($0.54/-117 at Kalshi)
Prediction site Kalshi offers moneyline contracts for each team. Our analysis projects a Mets win. That contract is currently trading for $0.54 per, which equates to -117 odds. That makes Kalshi’s contract more valuable than the best odds available at a sportsbook.
Why do we like it? While Peterson comes with a concerning 1.50 WHIP and allows 10.12 hits per nine innings, his 0.00 ERA suggests he bends without breaking. More important, New York’s bullpen has been practically unhittable, posting a 1.776 ERA and a 1.14 WHIP compared to San Francisco’s relief ERA of 3.375. That bullpen depth will be the ultimate difference-maker late in the game.

Over/Under Prediction: Under 7.5 Runs (-112 at BetMGM): With both teams hitting near the Mendoza line—New York at .211 and San Francisco at .201—the data heavily supports a low-scoring affair. Furthermore, Giants starter Robbie Ray has been exceptionally stingy with baserunners, carrying a 0.938 WHIP. Expect a tight, pitching-dominated contest that stays beneath the projected total, perfectly aligning with the 100% under trend for the road squad.
