John Feltman’s Mariners vs Blue Jays Preview
Seattle Mariners Betting Preview: Woo Needs Some Help From M’s Bats
Woo gets the ball tonight for the Mariners, who have gotten off to a strong start in 2025. Woo enters tonight’s game with a 2-0 record and an ERA under 3.00.
His strikeout numbers are aligned with last season, but there’s a lot to like about what we’ve seen from Woo thus far. His most significant issue in the past has been his ability to stay healthy, as he only threw 121 innings last year.
He doesn’t have elite strikeout stuff, but the underlying metrics suggest his elite walk rate and ability to limit hard contact will lead to more success moving forward.
It’s a decent matchup on Friday for Woo, as the Blue Jays aren’t scoring a lot of runs to begin the season. They rank outside the top 18 in runs scored per game, so it could be another strong outing for Woo.
The Mariners’ offense worries me on Friday, though. I’m unsure if they can get their bats going, and although the offense regained some life this week in Cincy, they still rank 15th in runs scored per game.
It’s a good matchup against Francis, but the Mariners still strike out far too often for my liking. If they continue to struggle to put the ball in play, it’ll correlate to many offensive inconsistencies.
I’m not running to back the Mariners on Friday, despite Woo’s decent matchup on the mound. I still need to see more from the offense to believe they can be trusted fully.
Toronto Blue Jays Betting Preview: Offense Needs to Wake Up
In limited history against Woo, the Jays are 1-for-10 against him. That’s a tiny sample size, but it’s worth noting.
This struggling offense has another tough matchup on Friday.
Francis has only faced Mitch Garver and Donovan Solano in the past, totaling two at-bats. He has the edge in that he’s never faced these hitters before, and adjustments could take some time.
However, despite this being a plus matchup for Francis, I have significant concerns about him. He enters Friday with an xERA of 6.01, which indicates he’s been extremely fortunate thus far.
His barrel, hard-hit and ground-ball rates are well below the league average among MLB pitchers. His whiff and chase rates aren’t the worst, but they’re still not sustainable enough for long-term success.
Francis finished last season with a 3.30 ERA, and I’m still waiting for the regression monster to kick in. I don’t love the matchup for the Mariners, but they hit right-handed pitching at a much higher clip than southpaws.
As for the Jays, I’m still waiting for their offense to fully wake up. They’re 20th in runs scored per game, and Vlad Guerrero Jr. only has one home run in April. Anthony Santander is still trying to heat up, and Bo Bichette is off to a miserable start at the dish.
Their team batting average splits suggest they’ve been a bit unfortunate in scoring runs. However, I still don’t like their matchup against Woo.
I’m flat-out selling this Jays offense; I can’t trust them at all right now. They’re crushing left-handed pitching thus far, but they’re batting a modest .243 against right-handers.
Mariners vs Blue Jays Prediction, Betting Analysis
The best bet for Friday’s game is the under. I’m a little worried about Francis getting knocked around a bit, but the Mariners still strike out far too much, and those empty at-bats could kill a lot of innings with runners on base.
Francis still has average whiff and chase rates, so we could see him benefit from a plus matchup.
As long as he can keep the ball in the yard, I think the Mariners will struggle to hang a crooked number on the scoreboard.
As for the Jays, I don’t love their matchup against Woo. I think their offense is better than what they’ve put forth thus far, but I guess Woo can silence these bats while he’s in the game.
Even if these bullpens falter, I’m confident that the game total will land below 8.
