Shane Prince scored twice during a three-goal first period and John Tavares had a goal and an assist in the New York Islanders' 5-3 victory over the Tampa Bay Lightning on Wednesday night in Game 1 of their second-round playoff series.

Taking up where he left off in helping the Islanders advance beyond the first round for the first time in 23 years, Tavares assisted on Travis Hamonic's goal that erased an early deficit and later scored his sixth postseason goal on a blistering shot from the left circle to give New York a 4-1 lead midway through the second.

The Islanders needed overtime to get three of four victories against the Florida Panthers in the opening round. This one was never seriously in doubt after New York wiped out the 1-0 lead Tampa Bay took on Ondrel Palat's goal just over three minutes into the game.

Tampa Bay pulled to 4-3 on third-period goals by Nikita Kucherov and Valtteri Filppula before Cal Clutterbuck's empty-netter sealed the victory in the final minute.

Thomas Greiss, who won one game in overtime and two in double overtime against Florida, finished with 33 saves for the Islanders. They were outshot 28-10 over the last two periods.

Game 2 is Saturday at Amalie Arena.
