Astros bid to extend their AL West lead faces a still dangerous Detroit Tigers squad in the series finale on Aug 20. Valdez and Morton collide in a vintage two pitcher duel: Framber Valdez has been solid at 3.01 ERA but August has been unkind, while Charlie Morton has climbed back into form after a rough May, posting a 3.95-ish ERA since June. Houston sits 1.5 games ahead of Seattle entering Comerica Park, but Detroit has roared into the conversation in the Central and aims to complete a three-game sweep. Bettors favor Houston on the road, yet Detroit’s home underdog status and Morton's recent run indicate a tight test with run lines leaning toward the underdog Tigers. In the prop market, Valdez over 5.5 hits allowed looks prime due to Detroit’s stronger contact against lefties and Valdez’s late-season uptick in contact allowed. For fantasy managers, this one is a reminder that a stalwart ace can still crumble in August, while a veteran like Morton can flip the script and turn a series into a tilt that tilts rosters toward bats that capitalize on mistakes.
