Royals vs Giants MLB Betting Preview
Kansas City Royals Betting Analysis: Bubic on a Roll
Kris Bubic has been nothing short of a maestro this season, becoming the latest Royals farmhand to break out after years of teasing us with his potential.
He's finally back in a full-time rotation role after pitching out of the bullpen upon his return from Tommy John surgery a year ago.
He leans on a great strikeout-to-walk ratio and friendly contact in the air. He's roughly average when it comes to distributing his batted balls between groundballs and flyballs, and that's led to his only real weak spot: a middling 7.5% barrel rate.
Bubic, like a lot of pitchers this year, has experienced a pretty hefty jump in his pop-up rate to 11%, but even with this new phenomenon, it's still four points greater than the league average and five points ahead of his career average. That means this will likely regress and bring his expected numbers and his FIP down a bit.
Still, there's nothing bad we can really say about the left-hander. He's now made it through his last three outings with just one earned run against him across 18 1/3 innings — and that came on a solo homer.
A home run-hitting team would have the best chance against Bubic, and fortunately for the Royals, the Giants have struggled in that area lately.
San Francisco Giants Betting Analysis: Ray Day
We don't really talk about wins anymore, but I do think it says a lot about Robbie Ray that he's 6-0.
Yes, a record is no longer the best evaluator of a pitcher, but losses do still mean something almost every time a starter goes, and Ray's unblemished start has highlighted how he's given San Francisco a chance to win every time he takes the ball.
The southpaw is sporting a brutal 12.4% walk rate, which is nothing new, but he's continued to sport an excellent strikeout rate that checks in at 26.3% entering play on Monday.
He's pitched to more contact on the ground, something that's a little dicey when considering the Giants rank 26th in Outs Above Average in the infield. However, his contact has been largely friendly on account of his .210 expected batting average against.
I don't think Ray has the most sustainable profile around, given he lives in the extremes with walks and strikeouts, but the right matchup can make all the difference.
As a guy who's had a myriad of issues with home runs in his career and has taken a heavy flyball approach in the past, the ground balls are a welcome sight that have helped him keep things in a manageable spot.
Royals vs Giants Prediction, Betting Analysis
This is a dream spot for Ray, who will not only pitch in his friendly home park but deal to a Royals team that's arguably the most undisciplined in the league.
They're striking out in just 17.8% of plate appearances in the last two weeks, sure, but they're walking in just 6.1% — and their low .111 Isolated Power means they're waving at nearly every pitch and making weak contact.
Kansas City lacks the power bats to really put Ray in a spot of bother, and on top of that, it ranks just 27th in wRC+ against southpaws. San Francisco sits up in the 15th but has lacked power in the split with a .151 ISO. The Giants have also punched out on a hefty 24.6% of plate appearances.
Both pitchers should be in a good spot here, given that neither club has hit for power in the last 14 days or hit well against lefties.
While Bubic should rack up plenty of punch-outs, Ray should continue bringing his groundball rate up against a free-swinging bunch that won't be able to take advantage of his command issues.
Pick: First Five Innings Under 4 (-125 · Play to Under 3.5 at -105)
Moneyline
The sharp money is hitting San Francisco as a short home favorite here, and it has taken on 72% of the bets and 68% of the money.
Run Line (Spread)
Kansas City has covered in seven of its last 10 games, and the Giants are just 11-16 to the run line as favorites this season.
Over/Under
The sharps are also hitting the under here, which has taken 56% of the handle despite garnering 38% of the tickets. It's gone 17-10 in games the Giants are favored and 17-8-1 when the Royals are underdogs.
My best bet for this matchup is for both teams to go under the 5 total.
