Rays vs Royals MLB Betting Preview
Editor's Note: This written pick is a transcription from today's episode of the Payoff Pitch Podcast.
I took the Under 10.5 last night, and it’s come down to 10 today. It may actually be out of range now because I only like it down to 10 at about -105.
It’s 93 degrees at first pitch with the wind blowing out to left field at 15 mph — definitely offensive weather. But the lineups, especially on the Rays' side, aren’t really built to take full advantage of it. Junior Caminero will get a slight boost, and Yandy Díaz is capable of putting one out, but the walls they moved in at Kauffman are in right field, so the wind isn’t helping that shortened porch.
The Rays are an elite contact team but one of my worst power teams, so they’re not the ideal group to capitalize on this kind of weather. The Royals are much better set up for it — I give them elite plate discipline, a B+ power grade, an A+ Eye-rating (swing decisions), and C+ contact. There’s a lot of power up and down that roster.
I like the Rays' pitching staff to keep them in check here. We’ve talked about Griffin Jax — I had some reservations earlier about whether he could sustain this or might wear down. I was skeptical he could be a starting pitcher, but I’m coming around on him.
He’s starting to look like a Kenta Maeda-type guy with two elite secondary pitches (sweeper and changeup), both with around a 41% whiff rate and 265 wOBA against. If he can maintain that, he can be a solid “five-and-dive” starter before turning it over to a very good Rays bullpen.
Noah Cameron started the year rough but has rounded into form lately. He’s got an excellent curveball. Over his last five starts, the expected indicators have come back toward league average. So I see Jax as slightly above average (low-end No. 2 / high-end No. 3) and Cameron as a solid No. 3 / good No. 4.
I make the total around 9.75. I like the Under 10 at -105.
This lands in the 60-grade bet section. Despite adjusting for the weather as much as I could, I still couldn’t quite get to that 10.5. The market has also moved off 10.5, which makes me feel directionally correct.
That said, this is a pretty unique weather spot for Kansas City — extreme heat and wind like this are rare and only really happen in July and August, so I don’t want to completely underrate the offensive boost.
Pick: Under 10 (-105 or Better)
