WASHINGTON (AP) _ Chris Simon scored late in the second period to complete Washington's rally from a two-goal deficit Wednesday night and give the Capitals a 4-3 victory over the New York Islanders.

The Capitals, with 86 points, hold a four-point lead over the Florida Panthers atop the Southeast Division. It is Washington's biggest advantage this season.

Washington improved to 15-1-3 in its last 19 home games. The Capitals are 24-6-5 since Jan. 1, the NHL's best record.

Simon broke a 3-3 tie when he beat Kevin Weekes from the left circle for a power-play goal with 2:45 left in the second period.

The Capitals controlled play against an inept Islanders penalty-killing unit and scored two man-advantage goals in three chances, sparking their comeback from a 3-1 first-period deficit.

Washington rebounded after a shaky opening period that saw New York hold a 17-7 edge in shots. However, the Capitals outshot the Islanders 31-9 after that, dominating the second and third.

After Washington's Ken Klee scored 4:50 into the game, Josh Green, Brad Isbister and Johan Davidsson registered three goals within 10:59 for a 3-1 New York lead. Davidsson also added two assists.

The Capitals made it 3-2 with 21.8 seconds left in the period when Terry Yake knocked in a Jim McKenzie pass from in front. Yake also had an assist.

Washington missed on numerous good scoring chances before Peter Bondra tied the game at 3 with a power-play goal with 9:42 remaining in the second.
