MLB Parlay: Two Home Run Picks to Parlay on Monday, July 21 Feature Bryce Harper

If you're wondering who will hit a home run today, then you've come to the right place!

The 2025 MLB season is back from the All-Star Break today with a full slate, and there's a new FanDuel Sportsbook bonus available, offering "Five Days of Dingers" Home Run profit boosts, which we're pairing with the power of Dimers Pro for today's +3414 home run parlay.

If you're new to MLB betting, Dimers Pro offers a suite of MLB betting tools for users of all experience, whether you're using our best home run props or our full MLB predictions, there's something for everyone.

How To Use FanDuel's "Five Days of Dingers" Promo Boost

Opt in to the promo on FanDuel Sportsbook to receive a 50% Profit Boost Token to apply to any “To Hit a Home Run” wager for today's MLB games.

You can use the Profit Boost on any eligible straight or parlay home run prop—just note that there’s a maximum bet limit and a few restrictions (bonus funds, odds boosts, and cash-outs are ineligible).

Say you use your Profit Boost Token on home run leader and HR Derby King Cal Raleigh at +250. Your 50% Profit Boost Token turns that into a +375 bet, meaning a $25 wager will now win $93.75 instead of $62.50.

Dimers Pro gives you access to daily HR prop predictions —dozens of options on packed slates like today's—and highlights which bets carry positive expected value against the sportsbooks. Combined with FanDuel's weekly Dinger Tuesday boosts, that edge can turn a single swing into a big payday.

Home Run Bet: Jose Ramirez (Guardians)

• Game: Orioles vs. Guardians
• Dimers Probability: 16.6%
• Boosted FanDuel Odds: +556

J-Ram gets a tick in just about every box tonight as he looks to start the week of with a bang, literally. The Guardians get a cushy matchup against the Orioles with Tomoyuki Sugano on the bump to start things out. The 35-year-old has had an unspectacular year in his first Major League campaign, giving up 19 home runs from 18 starts on the mound. Given the averages, he's good for at least one dinger to Cleveland's bats tonight; but if all else fails in his start, the Orioles relievers aren't too much better at stopping the long-ball, ranking fourth-worst in the league for reliever dingers given up this year with 52. Ramirez ranks as our model's best chance to go deep for the Guards with a 16.6% probability.

Home Run Bet: Bryce Harper (Phillies)

• Game: Red Sox vs. Phillies
• Dimers Probability: 17.1%
• Boosted FanDuel Odds: +435

The boys in Philadelphia are primed to blast off tonight when they match up in nice conditions against the Red Sox and their starter Walker Buehler. Buehler is another pitcher that all home run bettors should be targeting with 17 dingers given up in 16 starts this season. While Kyle Schwarber is the most popular pick with our model - his FanDuel odds even with the boost aren't as good as Harper's, especially considering that defenses have a tendency to walk Philly's top slugger when they feel a threat, with Schwarber registering 68 BB this season (ranked 4th-most in MLB, 1st in Phillies) compared with Harper's 44 (32nd in the league, 2nd in Phillies). Harper has an impressive career record vs. Buehler with a .667 batting avg. This match up looks ripe.
