Martin (0-1) took the loss in the second game of Tuesday's doubleheader against the Royals, allowing one run on five hits and a walk over five innings. He struck out seven.
Making his big-league debut, Martin kept Kansas City mostly in check over 91 pitches (64 strikes), but he got outdueled by Brady Singer and had no margin for error. There doesn't appear to be any room for the 25-year-old in the Chicago rotation on a full-time basis with Johnny Cueto just added to the mix, but Martin has earned another callup the next time the White Sox need another arm.
