The New York Mets and Philadelphia Phillies open up a three-game series at Citi Field, and we’re breaking it down with our Phillies vs. Mets prediction. First pitch is set to fly at 7:10 p.m. ET on Monday (NBCSP, SNY).

I like the Mets to pick up a fifth win in seven meetings this season against their NL East rival. Mets right-hander Kodai Senga owns a sparkling 1.64 ERA in two career starts against the Phillies with 15 strikeouts across 12 1/3 innings.

Mets star slugger Pete Alonso is in a good spot to turn things around after a rough patch at the plate as we make our best Phillies vs. Mets bets.

The Mets have stumbled to a 7-13 record in August, allowing the Phillies to build a seven-game cushion atop the NL East. The Phillies, meanwhile, are 14-7 this month and own the second-best record in the National League. On paper, this looks like a matchup that should heavily favor Philadelphia.

However, the Mets had some success against Sanchez earlier this season, forcing him to throw 58 pitches in two innings with four hits and two walks in a 5-1 win. Sanchez owns a 3.89 ERA against the Mets in 10 career appearances. His WHIP and ERA have also been higher on the road than the friendly confines of Citizens Bank Park as I put together my Phillies vs. Mets prediction. The Mets are ninth in the league in home runs against left-handed pitching and have posted respectable numbers against southpaws in 2025.

The Phillies are a potent lineup, sitting ninth in the league in runs scored and 10th in home runs this season. Despite those strong numbers, Phillies hitters chase pitches at the third-highest rate in the league (30.1%), something I’m factoring into my Phillies vs. Mets best bet. Senga could utilize his devastating forkball to get Phillies hitters to expand the strike zone, leading to a strong outing.

Alonso has been scuffling at the plate of late, with just four hits in his 31 at-bats over the last seven games. I’m still riding with the polar bear to get back on track, as I offer my best Phillies vs. Mets player props.

Alonso has been excellent at home this season, registering an .888 OPS with 14 home runs and 55 RBI in 65 games. He’s had good success against Phillies pitching this season, slashing .292/.370/.500 with three extra-base hits, three RBI, and three runs scored in 24 at-bats.

❓MLB betting FAQs

How do betting odds work?

Betting odds represent the probability of a specific outcome and determine how much money you can win on a bet. There are three main formats: American odds, Decimal odds, and Fractional odds. In the U.S., American odds are most common.

What is the run line in baseball?

The run line in baseball is a form of point spread betting unique to MLB. It typically sets a standard spread of 1.5 runs, meaning the favored team must win by at least two runs to cover the run line, while the underdog can lose by one run or win outright to cover.

What does moneyline mean in betting?

The moneyline in betting refers to a wager on which team or player will win the game outright, with no point spread involved. It’s the most straightforward type of sports bet - just pick the winner.
