Matt Olson tops this board at 22%, tied with Rafael Devers for the highest price in the matchup. Atlanta’s first baseman gets the edge as our pick given his season-long consistency against a Giants opener making just his fifth career appearance. He’s been the steadier force in the middle of a red-hot Braves lineup.

Padres vs Reds: Best Home Run Bets Today

San Diego (72-65) sends Michael King to the mound against a Cincinnati staff that’s allowed 19 home runs over its last 10 games.

Fernando Tatis Jr. and Jackson Merrill are tied at 22%, but Tatis gets our nod as the top pick. San Diego’s star has been the most consistent power threat in this lineup all year, and Cincinnati’s staff has been about as generous as it gets with the long ball lately.

Wilyer Abreu sits atop this board at 16%. Boston’s outfielder gets the call as our pick, with Cal Raleigh‘s recent power surge, six homers over his last 10 games, still worth watching even outside the top spot.
