Keuchel (7-0) allowed two runs on four hits while striking out five over five innings in Tuesday's 12-2 win over Miami.
The Marlins reached Keuchel for a couple of first-inning runs on soft contact, but the left-hander quickly settled in and shut down Miami over the next four innings. The Astros put up crooked numbers in four of the first five innings to take an eight-run lead, which made it an easy and early night for Keuchel, who has now given up two or fewer runs in eight of his nine starts. His next turn through the five-man rotation comes Monday against the Tigers, though with a day off this week, he could pitch the series finale against Cleveland on Sunday on normal rest.
