Seattle Mariners vs. Arizona Diamondbacks: Late Night Baseball Bets

Cal Raleigh and the Mariners take on the Diamondbacks in Arizona tonight

Can Cal Raleigh contribute at the plate tonight for the Mariners?

Last night, the Diamondbacks held a lead all game long. They were up 1-0 after one, 2-0 after five, and 4-0 after seven innings. That lead held all the way until the 9th inning where the Mariners tied things up at four runs apiece, forcing extra innings. In the 11th, Josh Naylor walked things off in dramatic fashion with a grand slam to win, 8-4.

Tonight they go again. Will Seattle bounce back or do the Snakes roll in the desert?

Mariners vs. Diamondbacks Prediction: Diamondbacks Win, Over 9.5

Best Bets: Over 9.5 (-102) BetOnline

Let’s back some runs! The Diamondbacks are 5th in MLB in runs scored this season, while the Mariners are 14th, ranking in the top half of the league. Seattle jumps up to 11th in runs scored on the road.

Pfaadt has been blown up in his last few starts. He’s allowed five and eight earned runs in his last two, and hasn’t allowed less than three in six straight outings and seven of his last eight. The guy does not have it this year, and his 5.51 ERA speaks for itself. Three of his five pitches are below league average, including his fastball which gets thrown over 32% of the time. Plus the Mariners hit better on the road, watching their average jump from .240 to .261.

As for Evans, he’s given up eight earned runs in his last four starts. Three of his four most popular pitches are below league average, and we know how lethal the Diamondbacks’ offense can be. Arizona has two elite rated hitters, two others with a great matchup, and one more with an above average rating. I see both offenses combining for plenty of runs to clear this high total in the desert tonight.
