UNDATED (AP) — The Chicago Blackhawks and Anaheim Ducks are the third and fourth teams to advance to the NHL's conference semifinals.

Duncan Keith had a goal and three assists as the Blackhawks eliminated St. Louis 5-1 in Game 6. The defending Stanley Cup champs put together a four-goal third period and finished the series with four straight wins after dropping the first two games in overtime at St. Louis.

Chicago next faces the winner of the Minnesota-Colorado series.

Nick Bonino ignited and completed the Ducks' comeback in a 5-4 overtime victory at Dallas in Game 6. The Ducks erased a pair of two-goal deficits before Bonino scored 2:47 into OT to put Anaheim in the Western Conference semifinals against either San Jose or Los Angeles. Bonino and Devante Smith-Pelly tallied in the final 2:10 of regulation to force overtime. Smith-Pelly's second goal of the game knotted the score with 24 seconds remaining in the third period.

Jonas Hiller stopped all 12 shots faced after replacing Frederick Andersen midway through the second period.

The New York Rangers have taken a 3-2 lead in their best of seven playoff series with the Flyers. Brad Richards and Dominic Moore scored second-period goals to put the Rangers ahead 3-1 in a 4-2 victory.

Henrik Lundqvist stopped 24 shots for the Rangers, who can wrap up the series Tuesday in Philadelphia.
