💰 Best player prop bets for Blue Jays vs. Mariners Game 5
Our MLB player prop odds tool shows the best odds for every market across legal sportsbooks in your area.
⬆️ Vladimir Guerrero Jr. Over 1.5 hits, runs, and RBIs (-117) ⭐⭐⭐
Blue Jays 1B Vladimir Guerrero Jr. is on an otherworldly tear at the plate. After two quiet games in Toronto, he has six hits in his last nine at-bats with two home runs, four runs scored, and two RBIs.
Bryce Miller held Toronto’s bats in check in Game 1, but I have a difficult time seeing that level of success repeating itself. Miller was below average in several key metrics during the regular season, including average exit velocity, hard-hit rate, and expected ERA.
I like Guerrero to stay hot at the dish in Game 5. A $10 bet on Guerrero’s Over yields a profit of $8.55 at DraftKings. The -117 odds have an implied probability of 53.92%.
Our Mike Spector likes Vlad to drive in at least one run tonight in his best MLB player props today.
⬆️ Kevin Gausman Over 5.5 strikeouts (-125) ⭐⭐⭐
The Mariners have the third-highest strikeout rate in the postseason at 28.1%, and it's a bit higher at 28.7% through the first four games of the ALCS. T-Mobile Park was the most pitcher-friendly park during the regular season, and I'm anticipating a sharp outing from Gausman.
Blue Jays starter Kevin Gausman has enjoyed pitching in Seattle during his career, registering a 3.44 ERA with 54 strikeouts over 52 1/3 innings (nine appearances).
A $10 wager on Gausman to hit the Over on this player prop would provide a profit of $8.00 at BetMGM and has an implied probability of 55.56%.
⬆️ Cal Raleigh Over 0.5 RBIs (+156) ⭐⭐
Mariners catcher Cal Raleigh has dominated Gausman, with four home runs, eight hits, and a staggering 1.703 OPS in 17 career at-bats. He also had a pair of hits, including a game-tying homer off Gausman in Game 1 of the series.
A $10 winning wager on Raleigh to drive in at least one run would provide a profit of $15.60. The implied probability of the +156 odds is 39.06%.
Could that RBI come via a home run? Our best home run predictions today like the Big Dumper to go long.

💣 Daulton Varsho to hit a home run (+495) ⭐
Toronto outfielder Daulton Varsho has only two hits over his last five games (20 at-bats). Despite that, I like his matchup against Miller, who allowed a .556 slugging percentage off his fastball during the regular season.
Varsho had an excellent 15.9% barrel rate during the regular season and slugged an incredible .955 against offspeed pitches. That could serve Varsho well, as Miller has a splitter, a slider, and a knuckle curve in his arsenal.
A $10 winning bet on Varsho to hit a home run would provide a profit of $49.50 at DraftKings. The +495 odds carry an implied probability of 16.81%.
