WASHINGTON (AP) — Tomas Vokoun blanked his former team with a 20-save performance, and the Washington Capitals beat the Florida Panthers 3-0 on Tuesday night to improve to 5-0, the best start in franchise history.

Marcus Johansson, Alexander Semin and Jason Chimera scored for the Capitals, who led 1-0 heading into the third period.

Washington and Detroit are the only NHL teams to win all their games thus far. The Capitals' four-game winning streak at home to start the season is also a club record.

Vokoun was rarely tested, but he couldn't afford a slip-up in a tightly played defensive struggle. It was the 45th NHL shutout for the 35-year-old goalie, who played the previous four seasons with Florida. He left for the Capitals after failing to reach a contract agreement with the Panthers over the summer.

Pressed into extensive action while Michal Neuvirth works to return from a foot injury, Vokoun improved to 4-0 this season.

Vokoun wasn't the only player matched up against his old team. Florida's Matt Bradley and Tomas Fleischmann are former Capitals, along with goaltender Jose Theodore, who watched from the bench for the first time this season.

Florida's Jacob Markstrom stopped 29 shots in his first NHL start, but was victimized by Johansson in the first period and by Semin at 1:49 of the third period. Chimera scored into an empty net.

That was more than enough to provide the Capitals with their first 5-0 start. Each of their previous four games were decided by one goal, and three of those went to overtime.
