The Seattle Mariners will look to complete a series sweep as they host the New York Mets on Wednesday afternoon.
Seattle profiles well against New York starter Freddy Peralta, which is why I’m taking the home team to bring out the brooms in my Mets vs. Mariners predictions below.
Read on for more analysis and to get my free MLB picks for Wednesday, June 3.
Who will win Mets vs Mariners today: Mariners moneyline (-138)
The Seattle Mariners should be able to get another win behind George Kirby this afternoon. Kirby has an outstanding chase rate of 35.8% in 2026, which will play well against a New York Mets lineup chasing out of the zone 31.4% of the time.
Freddy Peralta has labored over his last four starts, putting up an ERA of 4.37 and a 1.54 WHIP in 22.2 innings of work. The Mariners' lineup has a .757 OPS against righties this season, and should hit Peralta hard. I’m taking Seattle to win as long as I can get at least a -150 payout.
COVERS INTEL: The Mariners are getting around on four-seam fastballs this year, pulling them in the air 21.3% of the time against righties. That’s a pitch Peralta throws 54% of the time.
Mets vs Mariners Over/Under pick: Over 7.5 (+113)
While Kirby should get the best of the Mets this afternoon, there are reasons to expect they’ll put up a little offense. New York has scored at least two runs in eight straight games, and Kirby is going through a rough patch, posting a 6.88 ERA over his last three starts.
If the Mets can post a couple of runs, I’m confident that Seattle will handle the rest of the total against Peralta, who is posting the worst hard-hit percentage (39.6%) and strikeout rate (23.9%) of his career so far in 2026. I’m backing the Over at even money or better.
