Detroit Tigers vs. Houston Astros Predicted Outcome

While Detroit enters the game as the stronger favorite based on form and standings, Houston offers betting value due to their projected likelihood to cover the run line. With total projections slightly favoring the under, a tight, low-scoring affair seems in order. Prediction: Astros keep it close, perhaps a 3–2 Tigers win, but with Astros +1.5 as the smart play.
