The Flyers eliminate the Penguins, the Canadiens and Golden Knights are on the verge of advancing to the second round, the Vezina Trophy candidates are revealed, and more in today’s NHL Morning Coffee Headlines.

RECAPPING WEDNESDAY’S PLAYOFF GAMES

NHL.COM: An overtime goal by Cam York gave the Philadelphia Flyers a 1-0 victory over the Pittsburgh Penguins in Game 6 to win their best-of-seven first-round series four games to two. Dan Vladar kicked out 42 shots for the shutout. Arturs Silovs made 31 saves for the Penguins. The Flyers will face the Carolina Hurricanes in the second round.

SPECTOR’S NOTE: York was so excited about scoring the series-winning goal that he hurled his stick into the crowd. After the game, he told reporters he didn’t realize what he’d done with his stick until well after he scored. York said he hoped no one was hurt in the stands. Fortunately, the fan who caught the stick wasn’t injured and was quite happy to have a memorable souvenir.

The Penguins dominated overtime but couldn’t solve Vladar. The loss raises questions about the future of long-time Penguins stars Sidney Crosby, Evgeni Malkin, and Kris Letang. Crosby has a year remaining on his contract, Letang has two years, and Malkin is slated to become an unrestricted free agent on July 1.

Vegas Golden Knights center Brett Howden scored a shorthanded goal in double overtime to defeat the Utah Mammoth 5-4 in Game 5 of their first-round series. Pavel Dorofeyev tallied a hat trick while Jack Eichel and Shea Theodore each had two points for the Golden Knights, who hold a 3-2 series lead. Clayton Keller had two points for the Mammoth. The series returns to Utah for Game 6 on Friday.

SPECTOR’S NOTE: The Mammoth were on the verge of winning this game until Dorofeyev completed his hat trick at 19:07 of the third period, setting the stage for Howden’s game-winner. The Golden Knights’ special teams made the difference in this one, going 1 for 5 on the power play while killing off five penalties and netting a shorthanded goal.

Mammoth forward Barrett Hayton made his series debut as he returned from an upper-body injury suffered on March 24.

The Montreal Canadiens nipped the Tampa Bay Lightning 3-2 in Game 5 of their first-round series. Alexandre Texier snapped a 2-2 tie early in the third period, Brendan Gallagher scored in his series debut, Kirby Dach got his second goal of the series, and Jakub Dobes stopped 38 shots for the Canadiens, who hold a 3-2 lead in the series. Dominic James and Jake Guentzel replied for the Lightning. The series returns to Montreal for Game 6 on Friday.

SPECTOR’S NOTE: Gallagher was a healthy scratch for the first four games, but got into this contest as Canadiens coach Martin St. Louis shook up his forward lines after a disappointing loss in Game 4. This win was a team effort by the Habs, who are getting production throughout their lineup as their top scorers have been largely neutralized.

The Athletic’s Pierre LeBrun pointed out that Lightning stars Nikita Kucherov, Brayden Point, and Andrei Vasilevskiy have not been at their best in this series. Kucherov seems frustrated. Point may still be hampered by the knee injury he suffered in January, while the veteran Vasilevskiy has not outperformed the inexperienced Dobes in the battle of the goaltenders.

Speaking of the Lightning, center Nick Paul missed this game with an illness.

HEADLINES

NHL.COM: Ilya Sorokin of the New York Islanders, Jeremy Swayman of the Boston Bruins, and Andrei Vasilevskiy of the Tampa Bay Lightning are this year’s finalists for the Vezina Trophy, awarded to the NHL’s top goaltender as voted by NHL general managers.

SPECTOR’S NOTE: Vasilevskiy will likely get the nod. Among goalies with 30 games played this season, the Lightning netminder is first in wins with 39, second in goals-against average (2.31), and third in save percentage (.912).

THE DALLAS MORNING NEWS: With their season on the line, the Stars need more from winger Mikko Rantanen. He single-handedly carried them into the second round last season, but has only one goal and six points against the Minnesota Wild in this series, none of them at 5 on 5.

SPORTSNET: Speaking of the Stars, team captain Jamie Benn was fined $2,604.17 by the league’s department of player safety for cross-checking Wild forward Ryan Hartman in Game 5 of their first-round series.

SPECTOR’S NOTE: The Wild hold a 3-2 lead in this series, with Game 6 on Thursday in Minnesota.

DAILY FACEOFF: Los Angeles Kings center Quinton Byfield played through two torn oblique muscles this season. He tore the right obliques just after the Olympic break ended. Once that healed, he tore the left oblique, which he played through for the remainder of the regular season and the Kings’ first-round series against the Colorado Avalanche.

SPECTOR’S NOTE: That would explain why Byfield finished with 49 points in the regular season and was held to just two assists as the Kings were swept by the Avalanche.

BUFFALO HOCKEY BEAT: Sabres center Noah Ostlund will be sidelined for “a period of time” after suffering a lower-body injury in Tuesday’s 2-1 overtime loss to the Boston Bruins in Game 5 of their first-round series. Josh Norris will likely replace Ostlund for Game 6 on Thursday in Boston. The Sabres lead the series 3-2.

THE HOCKEY NEWS: Carolina Hurricanes defenseman Alexander Nikishin returned to practice on Wednesday for the first time since suffering a concussion during Game 4 of their first-round series against the Ottawa Senators on Saturday. He sported a yellow non-contact jersey and could return to action for the Hurricanes’ second-round series against the Flyers.
