The Mariners and Astros have been on a collision course all season, and Sunday night in Houston they decided to settle things the loud way. Both lineups started teeing off early, and the Barstool betting account was locked in before the first pitch even landed, hunting for one more longball to cash a prop.

That's the setup: a +830 shot on Naylor going deep, tied to a bet-and-get promo that pays out bonus rewards just for firing off a $5 wager. Longshot bets like that are the whole appeal of a game already loaded with power — you don't need Naylor's number to hit to have a good night, you just need baseballs flying.
And fly they did. Randy Arozarena got Seattle on the board first, connecting for a solo shot that left the yard at 94.7 mph and traveled 365 feet, putting the Mariners up 1-0.

Arozarena's been Seattle's spark plug all year, the kind of hitter who can turn a quiet inning into a rally with one swing, and this one did exactly that. Houston didn't fold, but neither did the Mariners' lineup — a few innings later, Cal Raleigh got in on it too, launching his 13th homer of the season 327 feet with a 100.6 mph exit velocity to push Seattle's lead to 3-1.

"Big Dumper" going deep is never a surprise these days — Raleigh set the single-season MLB home run record for catchers with 60 bombs in 2025, so any night he connects tends to feel inevitable rather than shocking. With four homers already gone by the time the Naylor bet was still alive, the account behind that DraftKings wager was already sweating a good outcome regardless of whether the prop hit, noting the bonus rewards had effectively doubled with time still left on the clock for a Naylor dinger.
Whether or not Naylor actually delivers at +830, the bigger story is that Mariners-Astros games keep turning into track meets around the bases. Two clubs jockeying near the top of the American League don't usually trade haymakers like this in the middle of August, but Seattle's power surge — fueled by Arozarena and a red-hot Raleigh — has made every game against Houston feel like appointment viewing.
