Kimbrel is scheduled to make his Cactus League debut Wednesday, Gordon Wittenmyer of NBC Sports Chicago reports.
Kimbrel has been easing into spring training work, but he's scheduled to throw a bullpen Monday ahead of his first scheduled game action Wednesday. The 31-year-old joined the Cubs in June last season but experienced some struggles as he posted a career-worst 6.53 ERA and 1.60 WHIP as he converted on 13 of his 16 save chances. Although the right-hander's fastball velocity dipped slightly in 2019, he'll look to return to his past efficiency heading into 2020.
