Prediction: Seattle Mariners VS Arizona Diamondbacks 2025-06-09

The battle of the desert versus the Emerald City. The Arizona Diamondbacks, led by the powerful Corbin Carroll and his 18 home runs, are looking to take down the Seattle Mariners, who are countering with the mighty Cal Raleigh and his 26 homers.

The Diamondbacks are favored on the moneyline at -166, which isn't a surprise given their home-field advantage and Carroll's impressive power numbers. However, the Mariners have been a thorn in the side of favorites, winning 57.1% of their games as underdogs.

Merrill Kelly will take the mound for the Diamondbacks, while Emerson Hancock will start for the Mariners. The Diamondbacks' pitching staff has been a concern, with a 4.86 team ERA that ranks 25th in the league. The Mariners, on the other hand, have a more respectable 3.96 ERA, which ranks 17th.

Given the Diamondbacks' struggles on the mound and the Mariners' ability to thrive as underdogs, I'm going to take the Mariners +1.5 at 1.71. The over/under is set at 9.5, but I'm not convinced that either team's pitching can contain the opposing lineup, so I'll take the over at 2.0.

Best bet: Seattle Mariners +1.5 at 1.71.
