Tomas Hertl completed his hat trick by scoring in overtime, and the visiting San Jose Sharks withstood Alex Ovechkin's hat trick to beat the Washington Capitals 7-6 on Tuesday night. It was the defending Stanley Cup champions' sixth consecutive defeat.

Hertl scored 2:48 into the 3-on-3 session, and a handful of hats were tossed onto the ice. Many more cascaded down earlier after Ovechkin's third hat trick this season and gave him an NHL-leading 36 goals, but his big gamer came in a losing effort because of Evander Kane's dramatic goal that helped the Sharks end their three-game skid.

With goaltender Martin Jones pulled for an extra attacker, Kane beat Braden Holtby with a second left in regulation for his second of the night. Holtby allowed seven goals on 43 shots. Jones gave up six goals on 39 shots.

Ovechkin now has 23 career hat tricks and 643 goals, 14th on the all-time career list.
