CHICAGO (AP) — The Chicago Blackhawks are within three victories of their second Stanley Cup title since 2010 after winning the fifth-longest finals game in NHL history.

Andrew Shaw scored at 12:08 of triple-overtime to give the Hawks a 4-3 comeback victory over the Boston Bruins in Game 1 of the series. Michal Rozsival (ROH'-sih-vahl) fired a shot from the point that glanced off both Dave Bolland and Shaw before settling into the net.

The Bruins appeared to be in command once Patrice Bergeron (pah-TREES' BEHR'-zhur-ahn) scored a power-play goal to give his team a 3-1 lead early in the third period. But Dave Bolland tallied 1:51 later before Johnny Oduya (oh-DOO'-yuh) knotted the score with 7:46 left in regulation.

Bruins left wing Milan Lucic (LOO'-chihch) scored the game's first two goals and set up Bergeron's power-play tally. Brandon Saad (sahd) has a goal and an assist for the Blackhawks.

Chicago also got 51 saves out of Corey Crawford, who blanked the Bruins over the final 65:59. Tuukka (TOO'-kah) Rask stoped 59 shots for Boston.

Game 2 is Friday in Chicago.

PITTSBURGH (AP) — Dan Bylsma has been given a two-year contract extension by the Pittsburgh Penguins. The move comes just a week after the Eastern Conference's top seed was swept out of the NHL Eastern Conference final by Boston.

Bylsma is the second winningest coach in franchise history with a 201-92-25 since taking over as coach in February 2009.

PHILADELPHIA (AP) — The Philadelphia Flyers have picked up defenseman Mark Streit (stryt) from the New York Islanders for minor league forward Shane Harper and a fourth-round pick in next year's draft.

Streit served as team captain while helping the Islanders reach the playoffs this spring for the first time since 2007. Although he becomes an unrestricted free agent on July 5, the Flyers have exclusive negotiating rights until then.
