Houston’s bats have cranked up again and attention will turn to shoring up the pitching as the Astros go for a series sweep of the host Baltimore Orioles on Sunday afternoon. The Astros have scored 26 runs in the first three games of the series after going three consecutive contests without scoring less than a week ago. “Our team and how we stay together,” Houston manager Joe Espada said. The Astros’ power display has been led by first baseman Christian Walker, who has homered in each game of the series.
