Los Angeles Kings' goalie Jonathan Quick (No. 32) makes a save on San Jose Sharks' left-wing T.J. Galiardi (No. 21) in the second period during Game 5 of their NHL Western Conference semifinals playoff in Los Angeles Thursday. — Reuters NEW YORK — The Detroit Red Wings are on the verge of causing another postseason upset after their 2-0 victory over the top seeded Chicago Blackhawks in Game Four Thursday put them one win away from the Western Conference Finals. Seventh-seeded Detroit, who eliminated No. 2 seeds Anaheim in the first round, can seal the Western semifinal series with a win over the Blackhawks in Game Five Saturday in Chicago. After a scoreless first period, Detroit got on the board when Jakub Kindl scored on a power play midway through the second before Daniel Cleary sealed the win with an empty net goal in the final seconds. Detroit goaltender Jimmy Howard made 28 saves for his second-career playoff shutout. Chicago captain Jonathan Toews' struggles continued and he took three consecutive penalties in the second period. The Red Wings scored on the second of those power play opportunities. Toews has not scored a goal in the playoffs this season. Chicago, which won the President's Trophy for scoring the most points in the regular season, won the opening game against Detroit but has now lost three straight. Rangers 4, Bruins 3 OT: Chris Kreider steered in a pass from Rick Nash 7:03 into overtime, and the New York Rangers stayed alive in the Stanley Cup playoffs with a 4-3 victory over the Boston Bruins. New York, which erased 2-0 and 3-2 deficits in the critical Game 4 matchup in the Eastern Conference semifinals, still trails the series 3-1. The Rangers will need to win again Saturday in Boston to force a Game 6 back in Madison Square Garden. The Rangers, who were outshot 40-32, won a faceoff deep in their zone, and Nash rushed the puck up ice. He stopped above the right circle and fed a hard pass in front that Kreider skated into and tipped past Bruins goalie Tuukka Rask for his first goal of the playoffs. Kings 3, Sharks 0: Jonathan Quick made 24 saves in his seventh career playoff shutout, and Los Angeles moved to the brink of its second straight trip to the Western Conference finals with a victory over San Jose in Game 5. Anze Kopitar and Slava Voynov scored, and Jeff Carter added an empty-net goal as the defending Stanley Cup champions won their 13th consecutive home game in dominant fashion and lead the series 3-2. Antti Niemi stopped 26 shots for the Sharks, who have played more than 96 minutes without a goal since they appeared to be taking control of the series midway through Game 4. Game 6 is Sunday night at the Shark Tank. The home team has won every game in the series, and the Kings remained unbeaten at Staples Center since March 23. Roy is Avalanche coach Hall of Fame goaltender Patrick Roy, who backstopped Colorado to NHL titles in 1996 and 2001, has reached an agreement in principle to become the Avalanche's next coach. The team announced the deal Thursday making the 47-year-old Canadian the sixth coach in team history. In addition to two titles with Colorado, Roy led the Montreal Canadiens to Stanley Cup titles in 1986 and 1993.
