Who will win Mets vs Rays today: Rays -1.5 (43%)

For help understanding probabilities, see our odds calculator.

Robert Stock gives the Tampa Bay Rays a clear path to winning by multiple runs, and at 43%, I prefer the Rays run line to paying 62% on the moneyline. Stock has been dreadful this season, carrying a 7.40 ERA while opponents hit .307 against him.

His 4.90 xERA suggests he’s pitched a bit better than that ugly number, but even the kinder mark leaves a wide gap behind a locked-in Ian Seymour and a Tampa Bay staff that has been dominant lately.

If Seymour and the bullpen keep the New York Mets around two or three runs, Stock hands the Rays a clean path to the 5-2 or 6-3 result we need. 

I’d play Tampa Bay -1.5 to 46%.

COVERS INTEL:  Ian Seymour has settled into a groove, posting a 3.20 ERA with 49 strikeouts across 39 1/3 innings over his last seven appearances.

Mets vs Rays Over/Under pick: Under 8.5 (55%)

The Under at 8.5 is the play, built on the Rays’ pitching edge and a Mets offense that hasn’t done enough lately. New York is batting just .242 with 8.2 hits per game over its last 10, and while it has shown some pop, it hasn’t strung together the sustained scoring a big number requires.

The other side of the handicap is Tampa Bay’s own bats, which have cooled. The Rays are hitting .234 with a .347 slugging and 7.7 hits per game over their last 10, so something like five or six Rays runs is more likely than an eight-run outburst.

The market context is useful, too. The broader market has this game at 8.0 runs, so the 8.5 we’re getting is a meaningful extra half-run, especially when the likeliest Tampa Bay-winning scores are 5-2, 5-3, or 6-2.

I’d play the Under to 57%. At 8.0, I’d pass.

Mets vs Rays home run prediction: Junior Caminero (24%)

Junior Caminero hit his 37th home run on Sunday — pushing his hitting streak to 13 games — and he’s been Tampa Bay’s hottest bat, hitting .378 over his last 10 games.

His contact profile backs the power, headlined by a 93.0 mph average exit velocity and a 13.1% barrel rate. Caminero can attack Stock’s cutter, four-seamer, and sinker, which make up roughly 79% of his arsenal.

At 24%, we’re paying for Caminero’s status as Tampa Bay’s premier power threat, but the matchup justifies making him the selection over a longer shot.

I’d play Caminero to 26% for a quarter unit.
