Prop Bets: Seattle Mariners VS Arizona Diamondbacks 2025-06-09

The battle of the desert versus the Emerald City - Arizona Diamondbacks vs Seattle Mariners. The Diamondbacks are favored on the moneyline at -166, and for good reason. Emerson Hancock, the Mariners' starter, has been struggling to avoid contact with an ERA of 5.19, WHIP of 1.470, and FIP of 5.02. Meanwhile, the Diamondbacks' offense has been thriving, ranking top-8 in Contact Rate, RBIs, Total Runs Scored, and On Base Percentage.

I'm predicting a big day for Corbin Carroll, who already has 18 home runs under his belt. You can bet on him to go yard again, but unfortunately, I don't have the exact player prop bets available. However, I do know that Cal Raleigh has been crushing it for the Mariners with 26 homers, so keep an eye on him as well.

As for the game, the over/under is set at 9.5 runs per game, and with the Mariners' tendency to go over (33 out of 64 games this season), I'm inclined to bet on the over. Merrill Kelly will start for the Diamondbacks, and while he's a solid pitcher, I think the Mariners' offense will still find a way to score some runs.

So, my prediction? Diamondbacks win, but it's going to be a high-scoring affair. Take the over, and let's hope Corbin Carroll and Cal Raleigh put on a show!
