Rodon threw his first bullpen session of the spring Friday, despite having an upset stomach, Daryl Van Schouwen of the Chicago Sun-Times reports. "It was good to finally be back up there again," Rodon said. "It's been a while, but it felt good to get back up there. It's tough with a little stomach thing, but we still got it done."

Rodon said he was feeling better Saturday and is scheduled to throw another bullpen session Sunday. The White Sox are bringing the left-hander along slowly during spring training after he experienced some fatigue in 2016.
