BetMGM Bonus Code ROTOBG150 to Bet Padres-Phillies, MLB Odds
You'll have plenty of places on the diamond to land your first wager tonight. Below, you'll find a list of the most talked-about games on the schedule:
BetMGM Bonus Code Best Bets for Monday, June 30, 2025
- MLB: Padres at Phillies, 6:35 p.m. ET; use one of the top MLB betting sites for this NL matchup.
- MLB: Reds at Red Sox, 7:10 p.m. ET; use one of the best MLB betting promos on this interleague game.
- MLB: Giants at Diamondbacks, 9:40 p.m. ET; ; it's never too late to bet on World Series odds at BetMGM.
The Padres-Phillies kick off a three-game series, and some of MLB's best offensive players will be on full display at one of the most hitter-friendly environments. The Padres lineup is loaded with stars, including Fernando Tatis, Manny Machado and Xander Bogaerts. The Phillies get back injured star Bryce Harper tonight, he rejoins an already strong lineup that includes Kyle Schwarber, Trea Turner and J.T. Realmuto
In interleague play, we'll see a fascinating pitching matchup in the Reds-Red Sox contest. Flame-throwing Chase Burns just made his MLB debut last week, and now his second start comes against the Red Sox, who start Garrett Crochet, at Fenway Park. The hard-throwing Crochet should enjoy some success tonight against the Reds, who strike out around 23% of the time against southpaws.
Out West, the Giants-Diamondbacks renew their rivalry at Chase Field. Taking the mound for the Giants is Logan Webb, one of baseball's top pitchers this season with 12 quality starts in 16 tries. The current D-Backs' roster is hitting a combined .195 lifetime against Webb, and you can bet on his success in a number of different ways, including the Giants on the moneyline, or Webb's MLB player props.
But before you wager on any of that, get started by signing up with the BetMGM bonus code ROTOBONUS or ROTOSPORTS.
