"It was a step in the right direction. I'm pretty excited about that," Floyd said. "I wasn't 100 percent out there but I felt pretty good, pretty loose. It was more in between pitches that I was feeling it. It wasn't 'ouch.'"
"The last time he still felt something there," said White Sox manager Robin Ventura of Floyd. "So it keeps getting better."
Floyd plans on throwing another bullpen on Thursday, which would be a little longer and incorporate breaking balls.
"So that will be kind of the true test to see what happens," Floyd said.
Ventura added that even with a great start Monday, Hector Santiago wasn't guaranteed to start again Sunday in Floyd's place. Dylan Axelrod will return from Double-A Birmingham Tuesday and he will be in that mix along with Philip Humber.
