Best Home Run Prop Bets, MLB Player Prop Odds Tonight: March 31

The pursuit of dingers in our best home run prop bets today doesn't rest, even if our temperature here has cooled somewhat after a jet-fueled start on Opening Day.
Home run prop betting can be equal parts fun and frustrating given the inherent difficulty of the market (which is why, as always, a recreational play is best). But it only takes one crack of the bat at juicy plus-money odds to beef up your bankroll, and today we're targeting several hot sluggers in alluring matchups.
That includes Mookie Betts, who's part of the World Series odds-leading Los Angeles Dodgers and their imposing offense, and he's fresh off homer heroics.

π£ Best MLB home run prop predictions & expert picks today
Here's a breakdown of my best MLB home run prop predictions and expert picks today. Check out the rest of our MLB picks along with our guide on how to bet on MLB.
βΎ Brent Rooker (Athletics) to hit a home run βββ
Best odds: +420 via FanDuel (bet $10 to win $42)
Rooker's season last year was easy to overlook while he was buried in the annual mess that is the Athletics, and because the likes of Aaron Judge and Shohei Ohtani were blowing up the homer leaderboard.
But Rooker finished tied for fifth with 39 long balls, his second straight season hitting 30-plus. He did that on the strength of a barrel rate that ranked in the 97th percentile, according to Baseball Savant. And his OPS jumped from .817 in 2023 to .927.
Now he gets to face Ben Brown of the Chicago Cubs, who's making just his ninth career start and posted a 5.84 ERA during spring training.
π Cubs vs. Athletics home run odds
βΎ Cal Raleigh (Mariners) to hit a home run βββ
Best odds: +360 via FanDuel (bet $10 to win $36)
Raleigh squares off against Jackson Jobe in the latter's first career regular-season start. Jobe is a highly regarded Detroit Tigers pitching prospect with plenty of potential after being the third overall pick in 2021. But there will likely be some growing pains, and we saw that during spring training when he allowed five homers across five starts.
That's the primary motivation for this pick, but a tasty price always helps too.
Raleigh is a classic slugger who sells out for power, an approach that's resulted in 30-plus home runs in two straight seasons. His odds in this market will therefore often be short to reflect his homer-hunting ways. However, the +360 today at FanDuel is far more appealing than the +280 from Caesars.
π Tigers vs. Mariners home run odds
βΎ Mookie Betts (Dodgers) to hit a home runβββ
Best odds: +500 via FanDuel (bet $10 to win $50)
The white-hot Betts will get a chance to tee off on Grant Holmes, who gets a tough spot on the road against the baseball-pulverizing Dodgers while making his first start this season, and only his eighth regular-season start ever.
Holmes sputtered during his final spring training outing while giving up 10 hard-hit balls. More critically, the larger sample of regular-season action from him last year (when he pitched 68 1/3 innings) resulted in a mediocre hard-hit rate allowed that ranked in the 52nd percentile.
That's not ideal when facing Betts at any time, and especially not when the eight-time All-Star is off to a sizzling start after hitting two homers on Friday and going 4-for-8 at the plate so far.
π Braves vs. Dodgers home run odds
βΎ Taylor Ward (Angels) to hit a home run ββ
Best odds: +675 via Caesars (bet $10 to win $67.50)
New users only. Must use promo code. Min. $10 deposit. Max. bonus is ten 100% Profit Boost tokens. Profit Boost tokens expire in 14 days. Void where prohibited. Full terms.
While the rest of our picks today involve targeting certified sluggers, this one is centered around fading a human launchpad.
Miles Mikolas takes the mound tonight when the St. Louis Cardinals face Taylor Ward's Los Angeles Angels. Mikolas has ranked among the bottom 20 in home runs allowed during each of the past three years, a stretch when he's given up 25-plus dingers in each campaign. His expected slugging percentage allowed sat in the bottom 8% leaguewide last year, too.
That said, Ward can certainly do his part here and packs plenty of punch. He's coming off a career single-season high 25 round-trippers in 2024..
This is also a rare time when FanDuel is far behind the rest of the market. Caesars is offering the best odds for Ward at +675, with FanDuel down at +540.
