Karros (biceps) will start at third base and bat fifth in Friday's contest versus the Royals.
Karros didn't start the previous two games because of left biceps inflammation, but he's ready to roll in time for the start of the Rockies' homestand. The third baseman has experienced a mini-breakout for Colorado this season, sporting a .262/.362/.426 batting line with nine home runs over 102 games.
