The biggest question entering this series is Jose Guillen. He came up limping on a routine run to first base on Tuesday and hasn't been in the lineup since.
So will he be there tonight?
Early reports indicate that he feels he can come back as early as today but it's unclear if the Royals are going to ease him into things with the All-Star break coming up and all.
Meanwhile, Buehrle is riding a nice hot streak winning four of his last five starts. His only loss?
Yeah, against the Royals, who have won 10 of 13.
This is a big series for the Royals heading into the break. The White Sox are one of three teams they're chasing in the division. They could gain some ground against the Sox, who are leading the Royals by 7.5 games.
