Before today's home opener against the Yankees the Royals placed Jose Guillen on the disabled list after he partially tore his right hip flexor while running out a grounder at first. (Yes, I know, he was running it out!).
Anyways, Guillen's injury saved someone their big league job (at least temporarily) as the club needed to make a move today before the game to make room for starter Sidney Ponson to join the 25-man roster. I would imagine Guillen will miss several weeks with this injury and could miss an extended period of time. His hips have given him a lot of trouble the past few seasons.
