NHL: Hawks edge Bruins in third overtime

Andrew Shaw scored with 7:52 left in the third overtime to lift the Chicago Blackhawks to a 4-3 victory over the Boston Bruins in the opening game of the Stanley Cup finals on Wednesday.

Shaw was positioned in front of Boston goalie Tuukka Rask when the puck deflected off his right knee and into the net as Chicago took a 1-0 lead in the best-of-seven series.

Michal Rozsival's long shot from the blue line first deflected off the stick of Blackhawks forward Dave Bolland before changing direction a second time when it hit Shaw's knee, ending one of the longest overtime games in Stanley Cup history.

Brandon Saad, Bolland and Johnny Oduya also scored for Chicago, who are seeking their second Stanley Cup title in four years.

Milan Lucic had two goals and one assist, and Patrice Bergeron had a goal for the Bruins, who were coming off a four game sweep over Sidney Crosby's Pittsburgh Penguins in the league semi-finals.

Game two is Saturday in Chicago.

It is the first time these two Original Six clubs have ever met in the Stanley Cup finals, and it is the first time they have faced each other in the post-season since 1978.
