WASHINGTON – Rookie sensation Alex Ovechkin scored the tying goal and assisted on the go-ahead goal, leading Washington past Atlanta 6-4 Monday night and eliminating the Thrashers from playoff contention.

Atlanta entered the day ninth in the Eastern Conference but with a chance to reach the postseason for the first time in franchise history if it could win its last two games and get some help. Instead, the Thrashers’ four-game winning streak ended, and they will finish behind No. 7 Montreal and No. 8 Tampa Bay in the East.

Ovechkin was honored by the Capitals during ceremonies before and after Washington’s home finale, and he showed why in the third period with Atlanta ahead 4-3 thanks to former Capitals star Peter Bondra’s goal.

Ovechkin scored from the left slot on a pass from Ben Clymer to tie it 2:36 into the final period, then found Brian Willsie open during a two-man advantage for the score that made it 5-4 at the 8:58 mark. Matt Pettinger tacked on an insurance goal at 12:26, his second of the game, giving him 20 for the season. Ovechkin reached 52 goals and 105 points; both totals rank third in NHL history for a rookie.

Penguins 6, Islanders 1

PITTSBURGH – And he’s only 18.

Sidney Crosby became the youngest player in NHL history to score 100 points in a season, setting up three goals in a 6-1 Pittsburgh victory over the New York Islanders that may prevent the Penguins from finishing as the league’s worst team for the second season in a row.

Crosby’s three-point night gave him 62 assists, to go with his 38 goals, and tied Mario Lemieux (1984-85) for the team record scoring record of 100 points. Crosby also joined Hall of Fame forward Dale Hawerchuk of the Winnipeg Jets (103 points, 1981-82) as the only 18-year-olds to score 100 points in an NHL season.

EDMONTON, Alberta – Jarret Stoll scored a short-handed, tiebreaking goal in the third period to help the Edmonton Oilers clinch the eighth and final playoff spot in the Western Conference with a 4-2 victory over the Colorado Avalanche.

Niklas Kronwall and Andreas Lilja also scored and Henrik Zetterberg added two assists for Detroit, which trailed 2-0 before stretching its winning streak to eight games.

The Red Wings also made it 20 consecutive games (17-0-3) with at least a point, since their last regulation loss on March 7.
