CHICAGO -- Right-hander Reynaldo Lopez will start and make his White Sox debut on Friday night against Kansas City following his recall from Triple-A Charlotte earlier in the day. To make room for Lopez, the White Sox assigned lefty David Holmberg to the farm club.
The 23-year-old Lopez was acquired by rebuilding Chicago from Washington in December 2016 with right-handers Lucas Giolito and Dane Dunning for outfielder Adam Eaton.
Lopez appeared in 11 games for the Nationals in 2016, starting six, and was 5-3 with a 4.91 ERA. In 22 starts with Charlotte this season, he was 6-7 with a 3.79 ERA.
"His last four or five outings in the minor leagues have been very good, so we hope that will transition here," manager Rick Renteria said.
The White Sox also acquired minor-league right-hander Ryan Burr from the Arizona Diamondbacks on Friday for international signing bonus pool money. Burr, 23, has split the season between two A-level clubs.
