Former Czech forward and NHL star Petr Klima has died at the age of 58, the Edmonton Oilers announced Thursday.The cause of death was not immediately known.Klima was the first player to defect from then-Czechoslovakia to join the NHL in 1985. He made an instant impact with the Detroit Red Wings, recording 56 points (32 goals, 24 assists) on a team that finished with the fewest points in the league.Klima was involved in a blockbuster trade with the Oilers on Nov. 2, 1989. He was shipped along with Joe Murphy, Adam Graves and Jeff Sharples in deal that brought Jimmy Carson to Detroit along with Kevin McClelland and a fifth-round pick in the 1991 NHL Draft.Klima scored a memorable goal in triple overtime of Game 1 of the 1990 Stanley Cup Final to give Edmonton a 3-2 victory over the Boston Bruins. He had not played in the previous five periods of the contest for the Oilers, who went on to capture the Stanley Cup in five games.”We are deeply saddened to hear of the passing of Oilers alum Petr Klima & extend our condolences to his family & all loved ones,” the Oilers wrote on Twitter.
