CHICAGO -- Phil Humber will likely make another rehabilitation start at Triple-A Charlotte before rejoining the Chicago White Sox, according to manager Robin Ventura.

Ventura had not yet spoken to Humber, who arrived at the White Sox clubhouse on Saturday afternoon with his luggage in tow. Humber allowed two runs on five hits, struck out one and walked two in four innings of work for Charlotte on Friday. Humber, who has been on the disabled list since June 22 with a mild right elbow flexor strain, said his arm feels great. He threw 63 pitches on Friday.

“This past one my fastball command was pretty much where I wanted it to be,” Humber said on Saturday. “That was really what we were going for this start. The first one was just to make sure you feel good. This one really wanted to improve my fastball command and feel like I did that along with throwing sliders for the first time so that was a good step too.”

Humber said that if he does make a third rehab start, he would work on command of his off-speed pitches, which was the only thing he felt was lacking during this stint. Endurance, Humber said, has never been an issue this season.

“This year it hasn't been an endurance problem, it's been more of having to make good enough pitches to go seven innings,” Humber said. “But hopefully when I get back that's going to change. I definitely feel like I'm throwing the ball a lot better. I don't know what the results are going to be but I definitely feel like I'm throwing the ball a lot better.”
