UNDATED (AP) — For the second straight game the Anaheim Ducks had a chance to pull within one point of St. Louis for first place in the NHL's Western Conference. And for the second straight game, the Ducks lost to a team that's been eliminated from the Stanley Cup playoff race.

The Edmonton Oilers scored three unanswered goals in the second period of a 4-2 win over the visiting Ducks. Taylor Hall tied it with a power-play goal before David Perron's short-handed tally put the Oilers ahead to stay 3:04 later.

Former Anaheim netminder Viktor Fasth (fahst) stopped 34 shots for Edmonton.

The Blues lost for the second straight afternoon as rookie Jeremy Morin collected a goal and an assist in the Chicago Blackhawks' 4-2 win over St. Louis. Patrick Sharp scored the go-ahead goal for the Hawks, who picked up their third straight win and bolstered their chances for home-ice advantage in the first round of the Stanley Cup playoffs.

St. Louis leads the West by three points over Anaheim and by four over San Jose and Colorado.

Elsewhere on ice:

— Pittsburgh blew a 2-0 lead in the third period before Jussi Jokinen (YOO'-see YOH'-kih-nehn) scored the lone shootout goal to lead the Penguins past the Avalanche 3-2. Brandon Sutter scored twice in the second period for the Penguins.

— Brayden Schenn scored twice and Vincent Lecavalier (leh-KAV'-ul-yay) had a goal and an assist as Philadelphia dumped Buffalo 5-2 to end a four-game losing streak. Mark Streit (stryt) set up three goals as the Flyers pulled within two points of the Rangers for second place in the Metropolitan Division.

— Dallas suffered a 3-2 loss to Florida to stay just one point ahead of Phoenix for the final Western Conference playoff berth. Roberto Luongo turned back 35 shots and Sean Bergenheim scored the go-ahead goal with 4:31 remaining as the Panthers ended a five-game losing streak.

— Columbus solidified its hold in the eighth and final playoff seed in the East as Sergei Bobrovsky (bah-BRAHV'-skee) stopped 31 shots in the Blue Jackets' 4-0 shutout of the New York Islanders. Boone Jenner and Mark Letestu each had a goal and an assist in helping the Jackets move three points ahead of Toronto and New Jersey.
