Best Home Run Props Today

Colton Cowser Home Run Bet (+596)

Cowser is starting to find that sweet left-handed swing, already launching three homers in August. Ten of his 11 bombs this season have come against righties, and Friday brings a familiar target. Freddy Peralta has surrendered 15 of his 20 homers to left-handed bats and three already this month. Cowser has taken Peralta deep before, and this matchup is begging for an encore.

Randal Grichuk Home Run Bet (+513)

Grichuk sees a lefty Friday, and that’s usually when the fun begins. Eight of his 10 homers have come against southpaws, and he’s already taken Sean Manaea deep twice while going 6-for-19 against him. Manaea has served up 12 of his 16 bombs to righties and three over his last two starts.

Ildemaro Vargas Home Run Bet (+750)

Vargas is starting to find the launch button, crushing two homers over the last week. Six of his nine bombs have come against lefties, and he’s already taken Nick Lodolo deep in limited history. Lodolo has become a home run piñata lately, serving up four over his last three starts, while righties have crushed 11 of his 12 allowed this season.
