Dostal made 18 saves in the scoreless first period, including one on a breakaway by Nylander at 17:48.
"When he's on his game, he's an elite goalie," Cronin said. "He's terrific. He's quick. When he's out, he's attacking, he's an aggressive goalie, he's hard to beat. He's not one of the 6-foot-5 guys; he's a smaller guy, but he's really quick and when he gets out and challenges, he's hard to beat."
Ducks defenseman Ilya Lyubushkin also denied Matthews a goal in the first when he stuck out his stick and knocked the puck away just before it crossed the goal line at 3:42.
"He's doing it every night with the amount of looks he gets, and, obviously, how elite of a player he is and how he's always able to find space and create opportunities for himself, or obviously knowing where to be on the ice to get pucks off the pass," Tavares said of Matthews.
NOTES: Matthews became the first Maple Leafs player with 30 goals in 35 games or fewer since Frank Mahovlich in 1960-61. He moved into a tie for fourth with Tony Amonte for the most 30-goal seasons by a United States-born player. … Anaheim rookie defenseman Pavel Mintyukov went to the dressing room at 6:37 of the second period after getting hit into the boards near center ice by Toronto forward Bobby McMann, resulting in a five-minute major boarding penalty and a game misconduct. Mintyukov returned later in the period. … Ducks defenseman Radko Gudas and forward Ross Johnston were out with illnesses, and forward Ryan Strome is day to day with an upper-body injury. … Anaheim forward Troy Terry was placed on injured reserve before the game; he sustained an upper-body injury in a 2-0 loss to the Arizona Coyotes on Friday. … Ducks center Adam Henrique won 18 of 28 face-offs (64.3 percent).
