The Seattle Mariners and New York Mets settle their rubber match on Sunday Night Baseball.
The pregame narrative: New York is in a tailspin this month, going 3-11 without a series win. The Mets won yesterday, but are home underdogs in primetime with Clay Holmes pitching opposite Seattle’s George Kirby.
Check out my Mariners vs. Mets prop bets, featuring prop bets on Juan Soto and Eugenio Suarez.
Mariners vs. Mets prop bets
Best Bet: Soto to score (-112)
This is a smash play in my books, even if Soto is having a “down year” by his standards.
His .383 on-base percentage is the lowest mark of his career, but that amazingly still ranks eighth in MLB. Turns out having a league-best 17.4% walk rate will do that.
On any given day, Soto is likely to find the basepaths and have an opportunity to score.
The first-year Met went 1-for-3 yesterday and didn’t score, snapping a streak of eight consecutive games with a run. I like him to get back on the saddle against Kirby.
- Soto has a .405 OBP against righties this year, launching 24 of his 30 homers against RHPs.
- Kirby is allowing a .309 OBP to LHHs, much higher than his .240 OBP mark against RHHs.
- Soto is 3-for-3 off Kirby in his career.
The only worry here is trusting the Mets behind him to produce against a pitcher who has logged four straight quality starts.
But Brandon Nimmo, Pete Alonso and Jeff McNeil are a combined 4-for-10 off the righty, and I could also see Soto driving himself home with a bomb.
Key stat: Soto’s 87 runs rank third in MLB.
Best MLB picks
Suarez under 0.5 hits (+155): Suarez has been a mess this month, batting .135 over 14 games and going hitless in half of them.
He does have a knock in four straight, but that doesn’t faze me. Suarez’s 40.3% K rate this month is astronomical, and his season-long .226 xBA ranks in the 10th percentile.
The third baseman is an all-or-nothing bat with a ton of power, but things can get really ugly when he’s not seeing the ball well.
Holmes is far from an elite arm, but he has a respectable 3.71 ERA and keeps the ball out of the air at an elite rate (56.9% ground ball rate, 95th percentile).
The righty also has a 9.6% walk rate, which would help us out if he gives Suarez a free pass.
