López, 23, went 6-7 with a 3.79 ERA (51 ER/121.0 IP), 131 strikeouts and a .220 (101-460) opponents average over 22 starts with Charlotte this season, his first in the White Sox organization.

He was acquired by the White Sox from Washington on December 7, 2016 with right-handed pitchers Lucas Giolito and Dane Dunning in exchange for outfielder Adam Eaton. López went 5-3 with a 4.91 ERA (24 ER/44.0 IP) and 42 strikeouts in 11 appearances (six starts) with the Nationals in 2016, his first major-league season.

López will wear uniform No. 40.

Holmberg, 26, is 2-3 with a 3.55 ERA (20 ER/50.2 IP) and 28 strikeouts in 33 games (six starts) with the White Sox this season after his contract was purchased from Charlotte on May 4.
