Wayne Gretzky and Mario Lemieux never faced each other in the Stanley Cup Playoffs, but the hockey legends will be going head-to-head in the second round of the battle for the Greatest NHL Moment -- twice.
Six Gretzky moments and two by Lemieux have advanced to the second round of voting, which began Wednesday. First-round voting by fans took place Oct. 18-24.
A bracket of 64 moments, as determined by a blue-ribbon panel consisting of broadcasters from NHL national rightsholders NBC Sports Group, NHL Network, Sportsnet and TVA, has been cut to 32. The bracket is divided into four regions: Hart, Norris, Calder and Vezina.
In the Hart Region, Gretzky's 802nd NHL goal, which he scored March 23, 1994 with the Los Angeles Kings to pass Gordie Howe for the most in League history, goes up against Lemieux scoring five ways in one game for the Pittsburgh Penguins on Dec. 31, 1988.

In the Calder Region, Gretzky scoring 50 goals in 39 games in 1981-82 with the Edmonton Oilers is battling Lemieux's signature goal for the Penguins in Game 2 of the 1991 Stanley Cup Final.
Other Gretzky moments with the Oilers to advance: Scoring his single season-record 77th goal Feb. 24, 1982, which will face Detroit Red Wings coach Scotty Bowman winning the Stanley Cup for an NHL-record ninth and final time in 2002; setting the single-season points record in 1981-82, which is going against Toronto Maple Leafs forward Darryl Sittler's 10-point game Feb. 7, 1976; becoming the fastest player to 1,000 NHL points Dec. 19, 1984, which is up against the 2014 Winter Classic at Michigan Stadium; and his 51-game point streak in 1983-84, which will face Phil Esposito of the Boston Bruins breaking Bobby Hull's single-season goal mark.
