Mariners vs Astros player prop picks
Yordan Alvarez Over 1.5 total bases (-115)
Don't worry, the good people over at FanDuel are offering a 30% boost for this matchup, which gets Houston Astros slugger Yordan Alvarez up to +114 if you want to take advantage.
Regardless, the lone elite-rated hitter in this matchup on Batters-Box covers 100% of Seattle Mariners right-hander Bryan Woo's pitch mix. On top of that, in 21 elite ratings at home this season, Alvarez has recorded at least a hit 90.48% of the time, two hits 52.38% of the time, and has gone Over this prop 71.43% of the time.
Over the big fella's last 10 games, he owns a 50% hard-hit rate and 13.3% barrel rate. Woo has allowed the last 30 lefties he has faced to produce a 58% hard-hit rate and 21.1% ground-ball rate.
Alvarez has been crushing the baseball as of late, and he broke his home run drought on Friday. Look for more bases this evening.
Take this prop down to -120, or take his alt line of 3+ hits, runs, and RBI.
Taylor Trammell Over 0.5 hits (-135)
Astros outfielder Taylor Trammell doing the bare minimum this evening feels worth paying the $1.35 juice. The 28-year-old has been crushing right-handed pitching, generating a 53% hard-hit rate and 23.5% barrel rate while owning a .308 ISO and .462 SLG over his last 30 at-bats against righties.
With Woo allowing a ton of hard-hit balls to left-handed bats and Trammell swinging it so well against right-handed pitching, simply putting the ball in play and reaching base safely feels very doable.
Use the boost, or take this down to -140.
Hunter Brown Over 17.5 outs (-130)
Houston Astros right-hander Hunter Brown has been shoving all season long, and he draws one of the coldest lineups in baseball on Sunday night. The Seattle Mariners' offense over their last 21 games owns a 94 wRC+, .302 wOBA, and .678 OPS.
The top of the lineup has gone extremely cold over their last 30 at-bats against right-handed pitching. Taylor Ward, Cole Young, Randy Arozarena, and Dominic Canzone all have batting averages of .250 or worse, on-base percentages of .267 or worse, and barrel rates of 5% or worse.
Brown has been fantastic over his last five starts, posting a 3.81 ERA, 3.21 xERA, and 1.13 WHIP. The right-hander has also done a great job limiting hard-hit balls during that stretch.
With Brown owning the second-highest pitcher rating on the day, along with an elite-rated matchup wOBA, ISO, strikeout rate, and ground-ball rate, I trust him to go six full innings.
Take this down to -140.
