Kahnle worked around one walk to pitch a scoreless ninth inning in Thursday's 8-3 win over Kansas City.
As injuries have hit the White Sox's bullpen, relative unknowns like Kahnle and Anthony Swarzak have filled in capably. With the latest injury felling setup man Nate Jones (elbow), Kahnle is a realistic replacement as the eighth-inning bridge to closer David Robertson. The fire-balling right-hander has allowed one run and struck out 19 over 10 innings.
