Seattle Mariners vs. Toronto Blue Jays Prediction

If you’re betting on this game, first take note that this is going to be a YouTube game. You can only watch this game live on YouTube via the MLB channel.

I don’t know about you, but it seems like every time they’ve got games on YouTube, there’s scoring. Keep that in mind.

Now, I didn’t just pick this game because it was on YouTube and I expected runs. I picked this game and wager because of the numbers. But being on YouTube might help!

Justus Sheffield will take the mound for the Mariners. He’s now allowed 17 runs in 19 innings pitched in June and has given up 27 hits with eight home runs and nine walks.

Sheffield has literally allowed two home runs per game in each game in June. Now he’s going to be pitching in a minor league ballpark that has seen plenty of balls leave the yard this season.

The power has killed him all year long. He’s got an isolated power number of .198 to righties, as a left-handed pitcher and has given up with weighted on-base average of .360 or worse to both sides of the plate. The strike outs are limited and the walks are high for Sheffield.

That’s all a recipe for disaster.

However, it gets worse. Sheffield, as a lefty, will likely have to face an entire lineup of right-handed bats. The Blue Jays can stack righties throughout the entire lineup and although George Springer hasn’t hit lefties since returning, his career numbers say otherwise against lefties.

This could be a huge breakout game for Springer.

Sheffield is allowing nearly 50 percent of hard contact and righties are hitting an exit velocity average of 91.6 miles per hour. Those are some hot shots coming off bats against Sheffield.

The Blue Jays have only seen Sheffield once or twice in their careers but Springer is 1-2 with a walk and an RBI. Marcus Semien is 2-5 with four walks and just two strikeouts along with a home run.

Teoscar Hernandez has a double and two runs batted in while going 2-2 against Sheffield. Even Bo Bichette is 2-3 with two base hits against Sheffield.

The expectation is that the Blue Jays rake tonight. After scoring nine runs last night, there’s no reason why the Blue Jays can't score 10 tonight against Sheffield and the Mariners, who are obviously overachieving at this point.

There is also reason to believe the Mariners can stick around in this game and become a running partner. It’s not nearly as likely but Steve Matz is coming off the injured list and hasn’t pitched since mid-June.

Before he went to the IL, Matz was allowing plenty of power to righties with an ISO of .180. Righties in the Mariners lineup who could hit for power include Mitch Haniger, Luis Torrens, Dylan Moore and Tom Murphy. So there’s guys that can smack off Matz if he struggles. And because it’s his first game back, he might not even be able to go that deep in the game. That would mean more of the Blue Jays bullpen that has not been any good this season.

So with that, I’ll ride with the Blue Jays to go score over 5.5 runs in this game. It’s a high number but they’ve got a great match-up to look forward to.
