Mets vs. Mariners: Over 7 total runs (+105)
Neither the Mets nor the Mariners is having the type of season they hoped for, but both are currently playing some of their best baseball entering this series. The Mets are coming off scoring 25 runs in their three-game sweep over the Marlins, while the Mariners have won six straight while averaging 6.2 runs per game during those contests. Both teams have big-name offensive players, such as Juan Soto and Julio Rodriguez, and Soto hit a grand slam for the Mets in a 10-1 game on Sunday. The Mets are going with Austin Warren as an opener before throwing Sean Manaea (5.56 ERA). Given how both offenses are playing lately, the model projects the Over to hit in 66.2% of simulations.

Dodgers vs. Diamondbacks: Over 9 total runs (-105)
Shohei Ohtani, winner of three straight MVP awards, has homered in two of his last three games and is heating up at the wrong time for Arizona. He has nine home runs in 36 career games against the Diamondbacks, and he's 3-for-10 with two extra-base hits against Arizona probable starter Eduardo Rodriguez over the last three seasons. Ohtani has helped lift the Dodgers' offense as of late, with Los Angeles averaging seven runs per game over its last eight contests to move up to second in the sport in scoring at 5.32 runs per game. Arizona has capable offensive threats as well in Corbin Carroll and Ketel Marte to compete against the Dodgers' loaded offense with the likes of Mookie Betts, Kyle Tucker and Freddie Freeman. The model projects the Over to hit in 59.5% of simulations. Back the Over by claiming the latest BetMGM promo code CBSSPORTS here:
Nationals (-150) vs. Marlins
"There's some juice, but this line should be a lot juicier," SportsLine MLB expert Matt Snyder said. "The Marlins are a pitiful 8-19 on the road this season, and starter Sandy Alcantara has been lit up in his last two starts (and three of his last five). Nationals starter Cade Cavalli is underrated, as are the feisty Nats." Back the Nationals by claiming the latest BetMGM promo code CBSSPORTS here:
