The Baltimore Orioles and Boston Red Sox face off in a crucial AL East matchup on August 18, 2025, at Fenway Park. With the Red Sox sitting in 2nd place (68-57) and the Orioles struggling in 5th (57-67), this game carries significant weight for Boston’s playoff push.

Why This Game Matters

The Red Sox are fighting to secure a Wild Card spot, while the Orioles are playing more for pride at this stage of the season. Boston’s -118 moneyline suggests they’re the favorites, but Baltimore is coming off a 12-0 blowout win against Houston, proving they can still deliver surprises.

Key Storylines to Watch

Pitching Duel: Trevor Rogers vs. Dustin May
- Rogers (BAL) has been inconsistent, with a 4.50 ERA, while May (BOS) brings stability with a 3.80 ERA.
- Fenway Park’s hitter-friendly dimensions could play a role—will Rogers keep the ball in the park?
Injury Woes Impacting Both Teams
- The Orioles are missing key arms (Grayson Rodriguez, Kyle Bradish) and bats (Tyler O’Neill, Gary Sanchez).
- The Red Sox are without Triston Casas and Kutter Crawford, but Dustin May’s presence gives them an edge.
Recent Trends & Home vs. Road Splits
- Boston has been strong at home, while Baltimore has struggled on the road.
- The Orioles’ 12-run outburst vs. Houston may be an outlier—can they sustain that against May?

Betting Market Outlook

The total is set at 7 runs, indicating expectations of a moderate-scoring game. But with Fenway’s tricky outfield and two pitchers who can be volatile, will the Over or Under hit?
