Blue Jays vs Mariners player prop picks
Prop #1: Eugenio Suarez Under 0.5 hits
I played this in the first game of the series with the same pitching matchup and it looked good until the very last Eugenio Suarez at bat. I'll go back to it again for a lot of the reasons I listed in that matchup.
This version of Toronto Blue Jays starter Kevin Gausman is essentially a two-pitch thrower. The fastball and split finger make up over 80% of his throwing arsenal. That split finger is going to be tricky for Suarez to have success with.
The season-long numbers tell the story plainly. Coming into this matchup he's hit just .167 against the pitch with an expected batting average that follows closely. Almost as nearly as important are his very high strikeout rates against such pitches.
This is just a difficult matchup for the veteran hitter and there's the added benefit that perhaps the Seattle Mariners are feeling some renewed pressure with the series tied. The 34-year old has gotten exactly one hit in every game this series.
That's a bit of an anomaly when you consider that his longest consecutive games with a hit was six games and he exceeded four just seven times this year. Some standard regression should occur soon and this matchup is as good as any.
Prop #2: Bryce Miller Under 2.5 strikeouts
I'll take a shot on this one; not all of the reasoning has to do with Bryce Miller himself.
For starters, it looks like Seattle's best pitcher, Bryan Woo, will be available out of the bullpen tonight. Woo has arguably been the Mariners' ace this season, posting a 2.94 ERA and giving them some bonafide stopper outings when they needed it.
His presence likely shortens Miller's leash considerably. While the season isn't exactly on the line for Seattle in this game, you get the sense that this one is much more important for Seattle than it is Toronto.
Even when fully stretched out in Game 1, Miller went six innings and recorded only three strikeouts against this Jays lineup. He's not a big strikeout arm to begin with, and the Blue Jays strike out less than any team in baseball.
Combine that with some matchup-specific weaknesses, and there's a realistic path for him to exit early, likely before he reaches three strikeouts.
Prop #3: Julio Rodriguez Over 1.5 total bases
Not many have seen their World Series MVP odds move as much as Julio Rodriguez over the past week. And there's a good reason for that, he presents a pretty strong case for having the best postseason performance amongst Mariner players so far – at least from an overall standpoint.
Tonight is a relatively simple analysis: I like him to come up clutch when his team needs him the most. He also has a pretty good matchup.
It's not a surprise that J-Rod would have a .303 expected batting average against Gausman in his career. He's posted strong hard-hit and barrel rate numbers throughout his career while Gausman has been just about average when it comes to limiting that stuff.
Beyond that, though, Rodriguez profiles really well against the two pitches that he throws the most. I expect he'll lean on the things that have given him success in this matchup in the past which makes this price very appealing.
