Top goaltending prospect Carter Hart has joined Lehigh Valley after finishing his Western Hockey League season, but Lyon is doing plenty to make his own mark on Philadelphia's depth chart.
Lyon, 25, is completing his second pro season, having taken the No. 1 job from veteran Dustin Tokarski in the postseason.
Lehigh Valley had 104 points, second-best in the AHL, but has faced a treacherous path so far. Facing the first- and third-best regular-season offenses in the postseason, the undrafted Lyon (6-foot-1, 198 pounds) has shown he can handle the playoff grind.
Lyon limited Charlotte (Carolina Hurricanes), the No. 1 offense (3.45 goals per game) to four goals in four games, including carrying Lehigh Valley through a 2-1 five-overtime road win in Game 4 with 94 saves.
Toronto's offense ranked third in the AHL during the regular season (3.34 goals per game). After making 28 saves in a 4-2 loss in Game 1, Lyon made 44 saves in a 3-2 overtime loss in Game 2.
