We have a loaded 15-game MLB slate set for tonight, so let’s dive into all the action to get you some winners for the night ahead.
Kicking off the night, we have a great NL East matchup on deck as the Philadelphia Phillies will face the Atlanta Braves in a critical series, so we have a +1300 ultimate same-game parlay for the action. Elsewhere in the NL, the Los Angeles Dodgers are tied for the NL lead with the Phillies as they’ll face the Seattle Mariners tonight, and the Milwaukee Brewers will look to extend their five-game win streak against the St. Louis Cardinals.
Over in the AL, the New York Yankees have a narrow lead for the best record in the American, but that’s at risk tonight as they’ll have a huge series against the Cleveland Guardians in the Bronx. Behind them, the Baltimore Orioles are amidst an entertaining series with the New York Mets, the Minnesota Twins are in a tough series against the San Diego Padres, and the Houston Astros will look to continue their surge in the standings against the Boston Red Sox.
Remaining in the AL, we’ll focus on the Kansas City Royals, who keep quietly winning and are now just 2.5 games back of the Cleveland Guardians for the AL Central lead. Bobby Witt Jr. is shortening his AL MVP odds despite the uphill battle, and the starting rotation keeps pushing out solid performances, setting them up to be a very dangerous AL Wild Card team come October. Tonight, they’ll look to extend their win streak to six games against the Los Angeles Angels.
It should be a great night of baseball, so stay with SportsGrid to be covered on everything. Let’s ride!
