Mets vs. Phillies Prediction, Odds & Expert Picks: MLB Best Bets for Sept. 9

Last Updated: September 9, 2025 11:49 AM EDT • 5 minute read X Social Google News Link

Two division rivals clash again as we look at our Mets vs. Phillies prediction, with each team heading in the opposite direction.
The Phillies have won four of their last five games. Philly is expanding its NL East lead, while the Mets are clinging to the final NL wild-card spot after losing three straight contests. First pitch is set for 6:45 p.m. ET from Citizens Bank Park, with the Philles as the -130 betting odds favorite.
We're eyeing the Over on 8 runs in this game as part of our MLB picks, though the Phillies' offense is set to do much of the work there with Ranger Suarez's effectiveness key to our player prop.

⬆️ Over 8 runs (-110) ⭐⭐⭐⭐
Suarez is well-positioned to shine tonight, which we'll dive into more in a moment. He may still allow a couple of runs to contribute to this Over hitting, but we're primarily leaning on the Phillies' offense teeing off on Sean Manaea as the team continues to advance up the World Series odds.
That's been a frequent sight, especially across the lefty's last six starts when he's been consistently roasted while putting up a 7.81 ERA. He still racks up strikeouts and keeps walks low, but Manaea leans exceedingly hard on his mediocre heater, which has resulted in balls soaring quickly the other way.
He throws his four-seamer an overwhelming 61.4% of the time, despite a 91.6 mph average velocity that sits in just the 14th percentile, according to Baseball Savant. Opponents are slugging .500 against that pitch, and it's been a major factor in his HR/9 being at 1.6 (league average is 1.2).
So it's not difficult to envision a Phillies offense that sits seventh in OPS doing much of the lifting to cash this Over. If that happens, a $10 bet through these -110 odds at Caesars would translate to a profit of $9.09 on an implied probability of 52.38%.
Our Gabe Henderson also thinks Kyle Schwarber will do his part to get us Over this number, as outlined in his best home run predictions today.

⬇️ Ranger Suarez Under 5.5 hits allowed (-115) ⭐⭐⭐⭐
Suarez is lethal on lefties. Yes, that's unsurprising since he's a top-tier southpaw, but the hurler has been especially effective against same-sided batters this year while allowing a minuscule batting average of .202, far lower than his .258 against righties.
He does that while leaning heavily on a vicious sinker that lefties are batting only .208 against, with an average exit velocity of only 84.6 mph. Being able to silence the power of the Mets' many slugging lefties is key, a group that includes Juan Soto, Brandon Nimmo, Cedric Mullins, and the switch-hitting Francisco Lindor.
Suarez's success isn't limited to just lefties, though. He enters tonight with a shining 2.89 ERA achieved largely through suffocating hard contact, as his 30.1% hard-hit rate allowed rests in the top 1% league-wide.
A $10 bet on him to keep the Mets' hit count below 5.5 during his time in the game would lead to an $8.70 profit on these -115 betting odds from Caesars, which come with a 53.49% implied probability

How do baseball odds work?
When betting on MLB, the run line shows how many runs the favorite needs to win by in order to cash the bet. For example, a favorite of -1.5 must win by two or more runs to cover the run line, while an underdog at +1.5 must win outright or lose by one run to cover the run line.
Moneyline odds represent the payout for picking the outright winner (+200 means a $100 bet wins $200, while -200 means a $200 bet wins $100). Over/Unders let you wager on whether the combined total of runs will be higher or lower than the set number.
You can determine the payouts and implied probabilities for any wager - or convert odds to different formats - with our odds converter.
