When evaluating the betting lines for this matchup, my top play is the Padres Moneyline. San Diego enters this contest with a 12-6 straight-up record. They are 9-1 straight-up over their last 10 games, translating to a dominant 90.0% win rate. Conversely, the Mariners have struggled mightily as an underdog, winning just 33.3% of those contests.

The Mariners, who started the year as a strong World Series odds contender, are sending strikeout artist Luis Castillo to the mound to stifle a potent Padres lineup featuring Fernando Tatis Jr and Manny Machado. Meanwhile, the Padres will look to capitalize on their momentum and embrace their role as home underdogs behind veteran starting pitcher Walker Buehler.

Luis Castillo vs Walker Buehler Stats

The most glaring trend pointing toward a Padres victory is the extreme vulnerability of Castillo. Over 39 innings pitched, Castillo has ballooned to a 6.92 ERA, allowing opponents to mash at a .339 batting average. The Padres boast a .240 team average and an 89.0 mph average exit velocity. They are primed to generate plenty of base hits and avoid the double play.

Mariners vs Padres Stats

Looking at the underlying metrics, Buehler holds a distinct advantage in run prevention. Buehler is holding opposing hitters to a .234 batting average, relying on a pitch mix that induces weak outs rather than hard contact. Castillo has struggled mightily, yielding over 13 hits per nine innings. The Mariners’ offense provides little run support, batting a miserable .173 on the road.

Given the pitching matchup, I am also backing over 8.5 runs. The over has cashed in 70.0% of the Padres’ last 10 games. With Castillo yielding heavy contact and the Padres missing key bullpen arms, traffic on the basepaths will be heavy, leading to a high-scoring affair.

As for my favorite MLB props bet, I’m targeting Castillo over 4.5 Strikeouts. Despite his struggles with run prevention, Castillo’s swing-and-miss stuff remains intact. He averages 9.69 strikeouts per nine innings. Even if he gets chased early and gives up an RBI or two during a rough at-bat, he has the raw stuff to clear this low hurdle.
