Astros vs Mariners Prediction: Under 8.0
The Seattle Mariners, with a strong record of 9-1 in their last ten games, bring a hot streak into their matchup against the Houston Astros. Their offense has been solid, highlighted by Cal Raleigh’s recent record-setting home run, but they face a challenging pitching matchup. Logan Gilbert’s impressive 3.52 ERA and 1.05 WHIP should help keep the game low-scoring.
On the other hand, the Houston Astros have been struggling recently with a 6-4 record in their last ten games. Jason Alexander has been solid for the Astros with a 4.04 ERA and 1.30 WHIP, which suggests he’ll be able to limit the Mariners’ offense effectively. The combination of strong pitching from both starters leans towards a low-scoring game.
The historical head-to-head record between the Mariners and Astros also supports a low-scoring outcome. In their recent meetings, several games have stayed under the total, with a notable trend of the Astros outperforming the Mariners by a narrow margin. Additionally, both teams have been under teams overall this season, especially when the total is set at 8.0.
Considering the strong pitching matchups and recent trends, the prediction is for a low-scoring game. A projected final score of Mariners 4 – Astros 3 aligns with this expectation.
