Player Props to Watch
A prominent prop bet features Orioles catcher Adley Rutschman, who has emerged as a key player. He boasts a batting average of .291 with six home runs, alongside an impressive .893 OPS this season. Despite a recent slump, where he hit .217 over the last week, Rutschman has still managed to hit two home runs during this stretch.
Against Zack Littell, who has allowed 14 home runs in his eight starts, Rutschman’s chances are promising. Historically, he has performed well against Littell with a career batting average of .250. With Rutschman hitting .302 against right-handers this year, he could be a solid choice for a home run bet at +620.
Prediction for Orioles vs. Nationals
This matchup is poised for high-scoring action due to the struggles of both starting pitchers. Littell has an expected ERA of 7.64, with the Nationals allowing six or more runs in numerous games he has pitched. Meanwhile, Baz has had his own difficulties, allowing four or more runs in five of his eight starts.
Given both teams’ offensive capabilities—Baltimore ranking 11th and Washington 2nd in runs scored—the expectation is for a game that surpasses the total of 9.5 runs.
Given the current trends and pitching stats, the recommendation is to bet on the OVER 9.5 for this exciting matchup.
