However, McDavid responded quickly to cut it to 3-2 at 3:05. He took a return pass from Keith and deked Markstrom before tucking the puck past the goalie's right pad.
McDavid is the first player to get at least 20 points (six goals, 14 assists) in the first nine games of a postseason since Mario Lemieux (nine goals, 13 assists) in 1992.
"He's the best player in the world, and he's pushing himself," Hyman said. "When you're the best, it's easy to be comfortable because guys are chasing you, but it's hard to keep pushing and keep challenging yourself, and he's a guy who wants to win more than anybody."
Evan Bouchard tied it 3-3 at 15:03 of the second with a slap shot past Markstrom's blocker on the power play.
"We're kind of leaving our foundation a bit and playing into their hands," Flames defenseman Noah Hanifin said. "When you're playing those 4-on-4's and you're short a lot it's tough. We've got to clean that up for sure. 'Marky' made some huge saves for us and kept us in it."
NOTES:McDavid extended his multipoint streak to five games (five goals, nine assists). He is also the second player in NHL history to record eight multipoint games through the first nine games of a postseason, joining Darryl Sittler, who did it with the Toronto Maple Leafs in 1977. … Flames forward Johnny Gaudreau had two assists to extend his point streak to seven games (two goals, 10 assists). … Keith is the third-oldest defenseman in NHL history to get at least three points in a playoff game, behind Chris Chelios (40 years, 92 days in Game 6 of 2002 Conference Quarterfinals) and Nicklas Lidstrom (39 years, 364 days in Game 7 of 2010 Conference Quarterfinals, and 39 years, 3 days in Game 1 of 2009 Conference Semifinals). ... Ritchie has scored in both games of the series after getting three goals in 41 regular-season games.
