💰 Best player prop picks for Tigers vs. Mariners Game 1

Our MLB player prop odds tool shows the best odds for every market across legal sportsbooks in your area.

🔱 Randy Arozarena Over 1.5 hits, runs, and RBIs (-110) ⭐⭐⭐

Arozarena has earned a reputation as one of the best postseason hitters in recent memory. He has 11 home runs and a 1.104 OPS in just 133 postseason at-bats.

Arozarena had a higher OPS, more home runs, and more RBIs at T-Mobile Park compared to on the road.

A $10 bet on Arozarena’s Over yields a profit of $9.09 at BetMGM. The -133 odds have an implied probability of 52.38%.


⬆️ Riley Greene Over 0.5 RBIs (+250) ⭐⭐

Greene crushed right-handed pitching in the regular season, registering an .886 OPS with 32 home runs and 83 RBIs. He had a better OPS on the road and also has five RBIs in nine career at-bats against George Kirby.

I like the value here on a prolific slugger who finished the regular season seventh in the league with 111 RBIs.

A $10 wager on Greene to hit the over on this prop would provide a profit of $25.00 and has an implied probability of 28.57%. 


⬇️ George Kirby Under 6.5 strikeouts (-105) ⭐⭐⭐

Kirby finished the regular season with a solid 9.79 K/9 in 126 innings. The Tigers struck out 33 times in three games against the Mariners, and also finished the regular season with the fourth-worst team strikeout rate at 23.9%.

Despite that, this is still a high number for a pitcher who’s never been an extremely prolific strikeout artist. Kirby has also had issues against Detroit throughout his MLB career, struggling to the tune of a 7.48 ERA with nine home runs allowed in six starts (27 ⅔ innings)

A $10 winning wager on Kirby’s Under would provide a profit of $9.52. The implied probability of the -105 odds is 51.22%.
