Houston Astros @ Detroit Tigers Preview

The Houston Astros (69-55) travel to Comerica Park to open a three-game series against the Detroit Tigers (73-53). Both teams lead their respective divisions, setting up an intriguing matchup. The Astros are coming off a challenging homestand, going 3-3 and ending with a significant 12-0 loss to the Orioles. Houston has struggled since early July, posting a 14-20 record over their last 34 games, and their bullpen has a 6.12 ERA this month.

The Detroit Tigers return home after a successful 7-2 road trip, though they also ended their last series with a loss, falling 8-1 to the Minnesota Twins. Despite that setback, Detroit has been in better form recently, winning seven of their last ten games.

On the mound for the Astros will be right-hander Spencer Arrighetti (1-3, 6.38 ERA), making his fifth start of the season. Arrighetti has shown some struggles, particularly with walks (5.4 BB/9) and a high WHIP (1.47). For the Tigers, veteran right-hander Jack Flaherty (6-12, 4.76 ERA) will take the hill. While Flaherty's overall ERA is higher, he has a more favorable 3.79 ERA when pitching at Comerica Park, compared to 6.08 elsewhere. The Astros' offense has also been scuffling, with a .678 OPS since July 22.
