Bummer allowed two runs on one hit and two walks while striking out two in two-thirds of an inning during Thursday's spring game against the Reds.
This was Bummer's debut this spring. The left-hander has been a high-leverage contributor out of the bullpen, emerging as Chicago's primary setup man during a breakout 2019 campaign. A biceps injury limited him in 2020, but he returns as a setup option from the left side in front of closer Liam Hendriks.
