The rotation has been up to the task in the team's 4-1 start, posting a 1.78 ERA and 36 strikeouts. Justin Verlander set the tone for the starting pitchers with his Opening-Day victory and attempts to keep his perfect regular-season record as an Astro intact against the Orioles, who are batting .129 and have been outscored 19-3 during their three-game losing streak.
