In the early morning hours Thursday Pittsburgh made a surprise deal that brought Jarome Iginla to the Penguins from Calgary in exchange for two young forwards and this year's first-round draft pick.
Iginla, Calgary's all-time leading scorer and in his 16th season with the Flames, had reportedly been headed to Boston before the deal with Pittsburgh was made final.
It was the latest move for a Pittsburgh team that with its win over the Jets took over the NHL points lead from Chicago and is currently dominating the Eastern Conference.
Pittsburgh also recently added Brenden Morrow, who had been the captain of the Dallas Stars.
With the additional firepower ready for the playoffs, the Penguins stormed to another win Thursday with Pascal Dupuis producing his 16th and 17th goals of the season. His scores both came in the second period after Chris Kunitz and Evgeni Malkin tallied in the opening stanza.
Vokoun, in his first season with Pittsburgh, took over in goal after regular starter Marc-Andre Fleury was injured in a 1-0 victory over Montreal on Tuesday.
Al Montoya made 39 saves for Winnipeg, which had won two straight.
