LAS VEGAS — William Karlsson had a goal and an assist in his season debut, and the Vegas Golden Knights handed the San Jose Sharks their ninth straight loss with a 7-3 win at T-Mobile Arena on Saturday.

Karlsson had missed the first eight games because of an undisclosed injury.

Mark Stone and Pavel Dorofeyev each had a goal and two assists, and Brett Howden scored twice for Vegas (6-2-1), which was coming off a 6-4 win against the Ottawa Senators on Friday. Ilya Samsonov made 24 saves.

Mikael Granlund, Nico Sturm and Luke Kunin scored, and Vitek Vanecek made 35 saves for San Jose (0-7-2).

Tanner Pearson gave Vegas a 1-0 lead at 1:57 of the first period with a one-timer from the left circle off a pass from Karlsson.

Jack Eichel extended the lead to 2-0 at 3:47. Following a face-off win, Eichel skated into the left circle and scored short side with a one-timer off a diagonal cross-ice pass from Stone.

Howden made it 3-0 at 16:46, finishing a cross-ice pass from Tomas Hertl near the left post.

Granlund cut the lead to 3-1 at 10:13 of the second period, jamming in the puck at the right post.

Karlsson pushed it to 4-1 at 11:10 with a short-handed goal. Vanecek came deep out of his crease to play the puck, but Karlsson won the footrace and poked it away from him. He then skated back up into the right circle and scored before Vanecek could get back into position.

Dorofeyev made it 5-1 with a power-play goal at 19:26.

Sturm scored 15 seconds later to make it 5-2.

Stone made it 6-2 at 11:10 of the third period, scoring from the left circle off a no-look pass from Eichel as he skated around the net.

Kunin cut it to 6-3 at 13:29, jamming in a rebound in the crease.

Howden scored his second of the game at 17:07 for the 7-3 final.
