Blue Jays vs Mariners predictions
Blue Jays vs Mariners best bet: Shane Bieber Over 4.5 strikeouts (-155)
Toronto Blue Jays starter Shane Bieber is in an ideal spot to rack up multiple punchouts against the Seattle Mariners today. Over the last 14 days, Seattle’s lineup has been highly prone to chasing, posting a glaring 27.0% strikeout rate.
Bieber’s lifetime rate of over one strikeout per inning, combined with a five-pitch mix that generates heavy horizontal and vertical movement, gives him multiple paths to exploit this matchup.
Facing a Mariners lineup currently whiffing at a top-five rate, five strikeouts projects as a very attainable floor.
COVERS INTEL: The Mariners are striking out at a 27% clip across the last 14 days, sporting a 77 wRC+. 
Blue Jays vs Mariners same-game parlay (SGP)
Bieber should exploit a lost Seattle lineup that is striking out at a 27% clip. Meanwhile, the Blue Jays, anchored by Vladimir Guerrero Jr., look to ruthlessly hammer a vulnerable Logan Gilbert, who is coming off a tough outing in Cleveland.
With both bullpens sporting unstable peripherals and constant late-inning traffic expected, the game projects to eclipse 7.5 total runs, with Toronto securing a moneyline victory.
Blue Jays vs Mariners SGP
- Shane Bieber Over 4.5 strikeouts
- Blue Jays moneyline
- Over 7.5
Blue Jays vs Mariners home run pick: Vladimir Guerrero Over 0.5 home runs (+575)
Guerrero should leave the yard against Gilbert today. Vladdy completely dominates this head-to-head matchup, boasting a massive 1.309 OPS and two career home runs off the Mariners' right-hander.
Gilbert is highly vulnerable following a shaky four-earned-run shellacking against Cleveland, making him target practice for Guerrero’s elite hard-hit ability.
