Royals manager Ned Yost said that Aaron Crow will be used if a save situation arises Monday against the Astros. Jonathan Broxton threw 29 pitches over two innings Sunday against the Cardinals, so Yost would like to stay away from using him. Yost is also considering using him as a pinch-hitter under National League rules. Greg Holland and Tim Collins are also unavailable Monday and could be used as emergency outfielders.
