Houston visits Detroit to open a series with both teams perched at the top of their divisions. Arrighetti laces up for the Astros against Flaherty as Houston looks to rebound from a brutal weekend that saw Baltimore plate them 23-5 and drop a 12-0 result. Detroit just wrapped a four-game split with Minnesota and sits comfortable atop the Central, 8.5 games clear of Cleveland. The pitching duel shapes up as a fantasy-friendly ride: Arrighetti’s return has punch, Flaherty’s steadiness needs a spark, and the bullpens will likely decide this one late.

Odds and lines tilt toward Detroit, but NBC Sports’ model flags a Tigers win on the moneyline with a lean toward the over on 8 runs pushed by plays at Comerica. Look for a muted early game with potential late scoring as arms settle in, and fantasy managers should watch Arrighetti’s swing-and-miss upside after eight strikeouts in two DL-return starts, while Flaherty needs daylight to shake off a rough August.
