Doug Gilmour scored 56 seconds into overtime last night in Chicago to give the Blackhawks a 5-4 win over the San Jose Sharks.

Gilmour came down the right wing on a two-on-one, but instead of passing, beat Steve Shields with a shot that hit the crossbar and dropped down into the goal for his 17th goal of the season.

San Jose's Mike Ricci scored a power-play goal with 4 minutes 13 seconds left in regulation to cap the three-goal, third-period rally that forced the extra session.

Eric Daze and Michael Nylander each scored twice for the Blackhawks, who won for the fourth time in five contests despite squandering a 4-1 lead.

SENATORS 4, ISLANDERS 3: Marian Hossa scored with 1:03 left in overtime to complete a stunning comeback. Ottawa extended its unbeaten streak over host New York to 16 games.

Trailing 3-1 with 7:25 left, the Senators, already on a power play, drew a generous roughing call against New York's Eric Cairns.

Upset with the call, Cairns smashed his stick against the boards and then threw it away, drawing another two minutes.

Shawn McEachern and Jason York took advantage by scoring two minutes apart to tie the score.

New York, which lost its first overtime game this season, has not beaten Ottawa since Jan. 6, 1996.

BRUINS 3, THRASHERS 3: Dave Andreychuk scored with 30 seconds left in regulation as host Boston rallied from a three-goal deficit to earn the tie.

MAPLE LEAFS 5, CANUCKS 4: In Vancouver, Steve Thomas scored twice, including the game-winner with five seconds left in overtime.
