Mrazek made 20 saves in Wednesday's 3-2 win over the Devils.
Mrazek wasn't busy, but he got the job done, snapping a streak of four consecutive outings with four or more goals allowed. He had been waived when the Maple Leafs planned on bringing in Harri Sateri to complement youngster Erik Kallgren in net, but Mrazek went unclaimed while Arizona snatched Sateri up, giving the Czech netminder an opportunity to find redemption in Toronto. Mrazek and Kallgren should continue to share the crease until Jack Campbell (ribs) returns.
