The New York Islanders defeated the Boston Bruins 6-2 Wednesday night at home to close out the best-of-seven, second-round series in six games. The Islanders won the last three games to take control. They advance to the semifinals to face the defending Stanley Cup champion Tampa Bay Lightning, who eliminated the Carolina Hurricanes in their second-round series.The Islanders suffocated the Bruins with strong team defense backed by goaltender Semyon Varlamov, who won four of five starts in the series. New York is a deep team that doesn’t rely on one key scorer. On Wednesday night, the star was Brock Nelson, who tallied two goals. The Bruins got a pair of power-play goals from Brad Marchand, but two empty-net goals by the Islanders ended any hopes of a comeback. Tampa will be powered by Nikita Kucherov, who leads all playoff scorers with 18 points, while Steven Stamkos gives Tampa a 1-2 punch. The Isles will again rely on balanced scoring.
