Floyd definitely will have his start skipped on Monday in the series opener against the Twins at U.S. Cellular Field, most likely replaced by long reliever D.J. Carrasco. The right-hander's potential remaining starts will be dictated by how Floyd responds to treatment and how close the White Sox are situated to first place in the American League Central by the start of next weekend's home set with the first-place Tigers.
"The main thing for us is to make sure we keep this guy healthy for the future," said Guillen of Floyd. "We know we are fighting for something and we are trying to get there.
"In the meanwhile, I'm not going to put this kid in to go out and pitch two innings and see him the way we saw him the last two outings. It's not fair for him or for us. Hopefully, we can skip him one start, and if we are still in the pennant race, we can put him back there."
Floyd started in Wednesday's 4-1 loss to the Mariners and lasted a season-low three innings due to the bothersome left hip pain, which actually is pain located closer to his left buttocks, according to Floyd. Guillen mentioned that Floyd was bothered by the same hip problem during his previous start in Anaheim, and Floyd added Thursday that the hip has caused trouble for more than a month.
"It has been getting worse," said Floyd, who gave up three runs on four hits against Seattle. "That's why they took me out, because obviously it hasn't been getting better. That's why they think maybe a start off will help things out."
"You see this kid and he can't even walk because he's so tight," Guillen said. "It's not a big problem. They do all sorts of tests and they don't show anything. It has to be something out there when the kid can't even walk. That's how I look at it."
Some personal goals for Floyd remain on target if he's able to return. He currently has a .500 record, at 11-11, and needs seven innings to reach 200 for the season.
Those personal goals won't matter, though, if the White Sox deem themselves as too far behind Detroit and Minnesota -- even with six games remaining on the schedule against the Tigers. Guillen added that Mark Buehrle, who will top 200 innings pitched for a ninth straight season with his start Friday against the Royals, could be another candidate for an early finish if the White Sox come up short in the next six games.
"We'll give Buehrle's start to [Jake] Peavy and Gavin's start to Peavy. Give him all of those starts," said Guillen with a laugh. "I think Buehrle, because he has a lot of innings piled up.
"But I have to continue to have a season and make those guys go out there and earn the money. For pride, to finish better. For money, because you are a free agent -- whatever the reason is. We have to show up and play the way we should play every day, no matter what our situation is."
