The Islanders traded goaltender Dwayne Roloson to the Lightning last night for defenseman Ty Wishart.
Roloson, 41, had been the backbone of the Islanders' recent 6-1-1 streak, and general manager Garth Snow decided to strike while his trade value was high.
Wishart, 22, has four goals and 14 assists in 31 games this season with the AHL's Norfolk Admirals. He played in five games with the Lightning in 2008-09 after being drafted by the Sharks with the 16th overall pick in 2006.
Roloson is one of 11 NHL goalies to play after turning 41. "He's a goalie that battles hard," Lightning coach Guy Boucher said. "He's done really well this year . . . It's an opportunity we wanted to jump on. It's an opportunity Steve [Yzerman, the general manager] felt you didn't want to miss."
The Islanders traded defenseman James Wisniewski to the Canadiens on Tuesday for a second-round draft pick.
