Astros starter Lance McCullers got off to a slow start, walking three of the game's first four batters and then couldn't get back on track in a loss to the Twins on Sunday.
McCullers would allow only four hits and three runs before departing after six innings, but Houston was held off the scoreboard until the ninth inning.
McCullers (5-5) went 0-2 in three August starts, allowing 11 earned runs in 13 1/3 innings.
