March 31, 2026, is shaping up to be an electrifying day on the diamond, with marquee matchups that are sure to keep fans on the edge of their seats. From the potential pitching duel in Baltimore to big bats in Cincinnati and Philadelphia, here's what to expect from today's top Major League Baseball clashes.

First up, the Texas Rangers head to Camden Yards to take on the Baltimore Orioles. With just a hair's breadth separating these two clubs, our GameSim model gives the Rangers a slight edge, predicting a 5.8 to 5.7 victory over the Orioles. In a game where every pitch counts, the anticipated starting pitchers, Jacob deGrom for the Rangers and Zach Eflin for the Orioles, will be under the spotlight. Both are expected to deliver over six innings with modest strikeout numbers, but deGrom’s slightly longer outing could be the difference-maker.
Look out for Corey Seager, who is projected to add some pop to the Rangers' lineup with a potential home run and just shy of an RBI. On the other side, Taylor Ward could be a key player for Baltimore, contributing with his bat as he aims to maintain a .261 average. With the Vegas over/under set at 8.5, this game could easily become a high-scoring affair.
Next, the Pittsburgh Pirates sail into the Great American Ball Park to challenge the Cincinnati Reds. Our GameSim prediction favors the Reds, with a 56% probability of coming out on top, edging the Pirates 4.9 to 3.8. Despite the Reds’ edge, Pirates' pitcher Bubba Chandler is expected to put in a solid performance with nearly five strikeouts over six innings.
The Reds’ lineup is bolstered by Eugenio Suarez, who’s batting an impressive .328 and could deliver a crucial home run. Ryan O'Hearn of the Pirates is also worth watching, bringing consistency to his team with a .333 average. This matchup, with a Vegas over/under of 9.0, promises plenty of action.
Finally, the fierce rivalry between the Washington Nationals and the Philadelphia Phillies resumes at Citizens Bank Park. The GameSim model gives the Phillies a 57% chance of victory with a predicted score of 5.5 to 4.0. Expect Andrew Painter to take the mound for Philadelphia, aiming to maintain a solid ERA of 3.23 across nearly six innings.
Kyle Schwarber stands out as a pivotal player for the Phillies, with projections suggesting a .338 average and potential long ball. Bryce Harper, though not as dominant as Schwarber, still poses a threat with his power. For the Nationals, Zack Littell aims to keep the Phillies’ bats at bay, hoping to build on his 4.98 ERA.
