2018-19 was Kuemper's first full season in Arizona and it went very well. Kuemper went 27-20-8 with a 2.33 GAA and .925 SV% in 55 games while filling in for an injured Antti Raanta. Entering 2019-20, Kuemper will be the Coyotes No.2 but showed he’s capable of handling the starting gig should the oft-injured Raanta miss time again. Kuemper is signed through the 2021-22 campaign.
