Since 2011-12, when Steven Stamkos of the Lightning scored 60 goals and Evgeni Malkin of the Pittsburgh Penguins scored 50, Ovechkin is the only player to have a 50-goal season; this is his fourth in that span. He scored 51 in 2013-14, 53 in 2014-15, and 50 in 2015-16.
"I mean, it's the milestone as a goal-scorer," Stamkos said. "He's done it plenty of times. That's why he's been the best scorer in the last 10-15 years. He did it again tonight."
Ovechkin is on track to win the Rocket Richard Trophy as the NHL's leading goal-scorer for the eighth time (Leon Draisaitl of the Edmonton Oilers is second with 47). That would break a tie with Bobby Hull for the most times leading the NHL.
Ovechkin would become the sixth player to lead the NHL in goals at age 33 or older, the first since Phil Esposito in 1974-75 (33 years, 45 days for the Boston Bruins). The other players to do so are Bill Cook in 1932-33 (36 years, 165 days for the New York Rangers), Gordie Howe in 1962-63 (34 years, 358 days for the Detroit Red Wings), Nels Stewart in 1936-37 (34 years, 82 days for the Bruins and New York Americans), and Maurice Richard in 1954-55 (33 years, 228 days for the Montreal Canadiens).
Ovechkin, with 658 NHL goals, passed Brendan Shanahan for 13th all-time.
"It's been, obviously, a phenomenal milestone year for him and it's going to continue to be for the next few years as well," Washington coach Todd Reirden said. "But, you know, 50 goals eight times is remarkable. How he's done this year, he's scored goals all different ways.
"We're so fortunate to have this player in Washington and playing for the Capitals. A generational talent. And, you know, the NHL is fortunate to have a guy like this. We're spoiled in Washington for sure, but the whole National Hockey League is spoiled to have a guy like this. I'm happy for him because he put the work in. He put the work in and he deserves it."
