With the addition of left-hander Scott Kazmir in the rotation, the Astros have altered their rotation heading into the weekend series with the Royals.
Kazmir will open the series on Friday with Scott Feldman going on Saturday. 2015 All-Star Dallas Keuchel will wrap-up the series on Sunday.
Vincent Velasquez, who was originally scheduled to pitch on Saturday, will be available out of the bullpen, according to manager A.J. Hinch.
