Red Sox vs Astros Preview
Hunter Brown will take the mound for the Astros with a 2.51 ERA and 0.98 WHIP this season.
At home, the right-hander has better splits with a 2.37 ERA and 0.92 WHIP compared to his 2.62 ERA and 1.03 WHIP on the road.
Walker Buehler will oppose him. After a difficult start to the season, the Red Sox starter has performed much closer to the level expected of him.
Buehler has not allowed more than three runs in any outing since the start of July.
This aligns with our Bet Labs recommendation for the under in this game.

This system targets unders in MLB series games (Game 2 or later) where both teams have winning records, suggesting quality pitching and competitive matchups.
However, public betting leans toward the over — likely expecting fireworks between top teams — which creates contrarian value on the under.
By capitalizing on low public support for the under (≤35%), the strategy fades public perception in favor of market inefficiencies, especially when bettors overestimate offensive output late in a series.
Pick: Under 8 (-115, Fanatics)
