Kahnle struck out all three batters faced in the eighth inning of Saturday's 6-4 extra-inning win over the Tigers.
With the White Sox holding a two-run lead entering the eighth inning, that's a spot normally reserved for Nate Jones. However, he was unavailable after pitching three times in the previous four days, so manager Rick Renteria went to Kahnle, who has been fantastic since being called up. After Saturday's performance, he has 19 strikeouts and a 1.00 ERA over nine innings. Jones remains the preferred choice to set up closer David Robertson, but Kahnle has worked his way into a key seventh-inning role in close contests while Chicago is without the services of Jake Petricka and Zach Putnam.
