OTTAWA - Marc-Andre Bergeron got his second power-play goal of the game early in the third and Mike Comrie scored later in the period, leading the New York Islanders to a 3-1 win over the Ottawa Senators on Sunday night.
Rick DiPietro made 31 saves for New York, which won its second game in a row to finish 2-1-2 on its five-game road trip, the team's longest of the season. The Islanders hadn't beaten the Senators in Ottawa since March 15, 2003.
Daniel Alfredsson scored a power-play goal in the second for Ottawa, which ended a four-game winning streak that included a 3-2 victory over NHL-leading Detroit on Saturday.
Senators centre Jason Spezza left the game following the first period after he was flattened by an open-ice hit by Islanders defenceman Freddy Meyer early in the game.
The Senators lost all-star right wing Dany Heatley, Spezza's linemate, for up to six weeks on Saturday when he dislocated his right shoulder during an awkward fall into the boards while he was trying to check Red Wings forward Dallas Drake.
Islanders forward Ruslan Fedotenko fell to the ice after he was hit in the head by Senators centre Mike Fisher's arm in the Ottawa zone 10:50 into the third. Fedotenko went to the dressing room and didn't return.
Ottawa was 9-0-1 in its previous 10 games against the Islanders, outscoring them 43-17 over that span.
Senators goalie Martin Gerber stopped 28 shots, including a sensational save earlier in the play that led to Bergeron's second goal when he lunged to his right to deny Comrie's shot at an open net.
After the Islanders regained the lead at 2-1 following Bergeron's second goal 4:36 into the third, Comrie beat his former teammate for an unassisted goal at 6:16.
Comrie, who played 41 games with Ottawa last season and was part of the Senators' run to the Stanley Cup finals, burst down the right side and put a shot in off Gerber's right arm to give New York a two-goal lead.
Spezza had just received a pass from defenceman Wade Redden when he was checked by Meyer 3:47 in. The high-scoring centre got up and skated slowly and directly to the bench, where he sat and spoke with trainer Gerry Townend.
He returned moments later without missing a shift and finished the first period, but didn't come out for the second.
A team spokesman said Spezza was held out for "precautionary measures," though there was no indication of the nature of his injury.
Alfredsson took a bad penalty late in the first when he cross-checked Meyer from behind in front of the Islanders net.
It proved costly as Bergeron scored on the ensuing power play to give New York a 1-0 lead heading into the first intermission.
Alfredsson tied it at 1-1 with his third power-play goal in two nights 16:07 into the second.
Notes: DiPietro took a shot at the empty net in the final moments but his rink-long attempt went just wide of the left post ... With Heatley out, veteran left wing Randy Robitaille joined Alfredsson on Ottawa's top line before Spezza left the game ... Heatley ended a streak of 238 consecutive regular-season games. He has 125 goals and 139 assists in 207 games with the Senators since he was acquired before the 2005-06 season in the trade that sent Marian Hossa to Atlanta ... The Senators close out their season series with the Capitals on Tuesday in Washington (7 p.m., Rogers Sportsnet, Team 1200).
