(AP) — Patrick Kane and the Chicago Blackhawks continued their hot streaks on Wednesday.

Kane registered his second hat trick in three games as the Hawks earned their fifth straight win by whipping the visiting Pittsburgh Penguins, 4-1. He opened the scoring 8:49 into the second period and added a pair of insurance tallies after Richard Panik provided the tiebreaking goal with 24 seconds left in the period.

Scott Darling handled 36 shots and blanked the Penguins after Scott Wilson tied the game late in the middle stanza.

The Blackhawks' 10th win in 11 games leaves them three points behind the Minnesota Wild for first place in the NHL's Western Conference and Central Division races.

The Penguins remain seven points behind the East-leading Washington Capitals.

Meanwhile, the Tampa Bay Lightning continue to climb back into the Eastern Conference playoff race.

The Lightning are 7-1-2 in their last 10 games after beating Carolina, 4-3 on Victor Hedman's goal 46 seconds into overtime. Hedman scored twice for the Lightning, who also got a goal and two assists from Nikita Kucherov.

Tyler Johnson also scored and Andrei Vasilevskiy stopped 28 shots to help Tampa Bay climb within three points of Toronto for the final wild-card berth in the East.

NHL-TRANSACTIONS

Teams work on their rosters

(AP) — The NHL trade deadline passed Wednesday afternoon without the usual flurry of activity. The league said there were 18 trades completed involving 33 players, the lowest totals since 30 players were moved in 17 transactions four years ago.

The Avalanche traded veteran forward Jarome Iginla to the Kings for a conditional fourth-round pick in the 2018 draft. The deal came with Los Angeles one point behind St. Louis for the final Western Conference playoff berth.

The only other notable move involved the Detroit Red Wings, who traded veteran forward Thomas Vanek to the Florida Panthers for defenseman Dylan McIlrath and a conditional third-round pick in June.

In other deadline swaps:

— The Montreal Canadiens acquired forward Dwight King from the Kings for a fourth-round pick. The Habs also got fourth-line center Steve Ott from Detroit.

— The Pittsburgh Penguins picked up defensemen Mark Streit and Frankie Corrado in separate deals. Pittsburgh sent forwards Eric Fehr and Steve Oleksy and a draft pick to Toronto for Corrado. Tampa Bay got a fourth-rounder in 2018 for Streit.

— The Predators have added forward P.A. Parenteau from the New Jersey Devils for a sixth-round pick. The Devils also shipped Dalton Prout to Columbus for Kyle Quincey.
