The last time Petr Mrazek wore a Detroit Red Wings jersey to play in an NHL game was Feb. 18, 2018, when he made 31 saves on 34 shots in a 3–2 loss to the Toronto Maple Leafs. A day later, he was traded to the Philadelphia Flyers for two draft picks. The first time came five years before that: Feb. 7, 2013, when Mraek made 26 saves to beat the Blues 5–1 in his NHL debut.
