Seattle’s Monday loss marked its fourth in its last five games. The Mariners are 38-29 at home but with a -14 run differential in those games. Overall, the Mariners are playing .628 ball in 1-run games and .483 ball in every other type of contest.

Run line/Against the spread (ATS)

Seattle’s bullpen has registered an unsupportable 3.24 ERA in August. A .275 batting average on balls in play has tamped down what could easily be an ERA more than a run higher. Meanwhile, Houston’s ‘pen has shown some genuine improvement over the last month or so. The relief corps is a difference-maker in this matchup.

TAKE THE ASTROS -1.5  (+100) and consider pairing this play with the above in a half-and-half hybrid backing of the visiting nine.

Over/Under (O/U)

Looking at runs-scored figures and support analytics call into question the validity of both offenses. Other parts of the equation are filled with signals that swing both ways. PASS.
