The Seattle Mariners will look to stay hot as they welcome the New York Mets for the start of a three-game series on Monday night.
Seattle should have its way with New York’s pitching tonight, which is why I’m taking the home team to win in my Mets vs. Mariners predictions.
Let’s dig into tonight’s matchup as I explore my free MLB picks for Monday, June 1.
Who will win Mets vs Mariners today: Mariners moneyline (-130)
Seattle Mariners starter Emerson Hancock (4-2, 2.78 ERA) has dropped his WHIP to 1.01 this season behind his fastball. It’s one of the best pitches any starter is throwing this year, with Baseball Savant rating it in the 100th percentile for Fastball Run Value.
The New York Mets are giving Austin Warren his first start tonight, with Sean Manaea (0-1, 5.56 ERA) likely picking up the bulk of the innings. The Mets are 2-10 in Manaea’s appearances this year. This is a mismatch on the mound, and I like the Mariners to win at anything better than -150.
COVERS INTEL: The Mets are hitting four-seam fastballs and sinkers – pitches that make up more than 60% of Hancock’s arsenal – for line drives just 21% of the time against righties, the fifth-worst percentage in the majors this year.
Mets vs Mariners Over/Under pick: Over 7.5 (+105)
The Mariners have been effective against lefties this year, with 20% of all balls they’ve hit off of southpaws being pulled in the air. They should find success against Manaea, who has an average fastball velocity of just over 90 MPH, which will let those Seattle bats get around on him.
The Mets should provide something towards the total, as they’ve averaged 7.25 runs per game during their four-game winning streak. Even if Juan Soto and company can’t generate more than a couple of runs, the Mariners might get there themselves. I’m taking the Over at even money or better.
