Mrazek stopped 36 of 38 shots in Saturday's 5-2 win over the Oilers.
Mrazek didn't play well in his first outing of the year, but he did better in Saturday's contest, keeping a talented Oilers offense mostly at bay. The 32-year-old has allowed six goals on 64 shots while going 1-1-0 over two starts. He's likely to face a heavy workload in most games due to the Blackhawks' lackluster blue line. The team finishes a four-game season-opening road trip in Calgary on Tuesday.
