Best Home Run Predictions Tonight: MLB Odds, Picks & Prop Bets for July 21

We have a pair of Arizona Diamondbacks stars headlining our best home run predictions tonight, as Ketel Marte and Corbin Carroll are ready to launch some balls into orbit against the Houston Astros.

Meanwhile, maybe the Toronto Blue Jays continue to avoid pitching to Aaron Judge, but we're including him in our home run bets tonight because if he does see something he likes, it's getting nuked.

We'll combine those three picks with our fourth of the night, Teoscar Hernandez, to form our four-leg home run parlay today, which will pay out nearly $2,500 in profit on a $10 wager if it hits.

Carroll has hit three triples and a double in three contests since his massive home run in the All-Star Game. I'm betting that he gets to trot around the bases today rather than sprint.

The outfielder has completely changed his approach at the plate this year, and he's hitting the ball harder than ever before as a result. Sure, he's striking out more often and his .251 batting average is more than 30 points lower than what he managed during his epic rookie year, but he's already mashed 21 homers compared to his career high of 25.

I don't know how a guy who's 5-foot-10, 165 lbs is generating this much power on a regular basis, but Carroll has found a way, and I think we'll see that on full display tonight.

It's not as if Carroll needs any help, but Astros starting pitcher Colton Gordon also happens to be terrible and gives up a ton of homers. If he'd thrown enough innings to qualify among starting pitchers this season, his 1.73 home runs per nine innings would be the fourth-most in baseball.
