Dostal stopped 26 of 30 shots in Wednesday's 5-4 overtime win over Utah.
Dostal struggled with Utah's ability to get traffic to the front of the net. The 24-year-old Dostal was still able to earn his second win in as many starts, and he's allowed just four goals on 60 shots this season. He's set to hold down the No. 1 role in goal at least until John Gibson (abdomen) is ready to make his season debut. The Ducks' next game is a road contest in Colorado against the 0-4-0 Avalanche.
