White tossed his full repertoire of pitches, including his splitter and slider. It was the first time since the right-hander sprained his right middle finger during a start on May 20 that he used his offspeed pitches.
"If he comes in tomorrow and says he feels good, we'll move to the next step, which will be a simulated game on Monday," Tribe skipper Manny Acta said.
To this point, White has yet to encounter any setbacks. He said he expects to return within the next few weeks.
"It feels really good," White said. "I haven't really had any trouble yet or any setbacks."
In three starts for Cleveland spanning 15 innings, White posted a 1-0 record and a 3.60 ERA, striking out 13 and walking nine. He's the organization's No. 2-ranked prospect, according to MLB.com.
