MLB Prop Bets - Today's Home Run Prop Picks (7/17/2026)
Yordan Alvarez OVER 0.5 Home Runs (+245 Kalshi)
One home run hitter who has been a fixture in plenty of successful home run props already this season is Yordan Alvarez. The 29-year-old lefty has the second-most home runs in the MLB this season with 31 total long balls, which is second only to Kyle Schwarber.
Alvarez hit six of those homers in his last 11 games before the All-Star break, including this smash on Saturday:

Alvarez hit that moonshot in Texas, but 16 of his 31 homers have been at home, where he has a .361 batting average compared to just a .278 average on the road. Alvarez has a .355 ISO and .485 wOBA in his games at Daikin Park, and he'll look to pick up where he left off in a favorable matchup against the Orioles Dean Kremer.
Kremer has allowed nine homers in 22 innings this season, working to a 4.09 ERA. Lefties are 16-for-60 against him with seven of those nine homers, a .394 wOBA, a .383 ISO, and a 9.5% barrel rate.
Alvarez has an impressive 18.6%. barrel rate on the season, which gives him a strong chance to go yard on Friday if he can catch a barrel at home against Kremer.
Jake McCarthy OVER 0.5 Home Runs (+575 HardRock BET)
For a longer shot lefty, let's head to the Mile High City and look at a longer-shot lefty who is in a great matchup at homer-friendly Coors Field, where the forecast is for temperatures over 90 degrees. McCarthy will be going against Reds' righty Brady Singer, who has allowed 20 homers in 18 starts and ranks in the top 10 in home runs allowed this season.
Lefties have hit 14 of those homers against Singer while posting a 43.5% hard-hit rate, 11.3% barrel rate, and .381 wOBA. Singer is 0-5 in nine road starts with a 6.75 ERA and .331 batting average against him in his nine road outings this season.
McCarthy went into the break with some great momentum while solidifying his role as the team's primary leadoff hitter against righties. The 28-year-old lefty has already set a new career-high with 10 homers this season through 83 games.
He hit four of those homers in the last, while hitting .341 with an 11.8% barrel rate. He has hit seven of his 10 homers at Coors Field and eight of them against righties. He makes sense as a value play against Singer and has the potential to bring huge returns if he can get a hold of one in Denver on Friday night.
