David Ullstrom scored early in the third period to give the Islanders a big lead, and New York held off the Tampa Bay Lightning 4-3 Monday.
Coach Jack Capuano returned to the Islanders and guided them to their first win of the season. He missed the opening-night loss to New Jersey on Saturday because of surgery to remove a kidney stone.
Michael Grabner, Matt Martin and Kyle Okposo scored in a 12-minute span of the second period to put the Islanders ahead 3-0. Ullstrom gave New York a four-goal lead 91 seconds into the final period.
Martin St. Louis, Benoit Pouliot and Steven Stamkos scored in a 5½-minute stretch, pulling Tampa Bay within a goal with 12 minutes left.
