Sharks 4, Coyotes 1: Tomas Hertl scored twice in his second NHL game as host San Jose cruised past Phoenix.

Patrick Marleau and Logan Couture also tallied, Joe Pavelski and defenseman Marc-Edouard Vlasic notched two assists apiece and Antti Niemi made 22 saves for the Sharks, who went 2-for-4 on the power play after going scoreless on eight opportunities in the season opener.

Blue-liner Oliver Ekman-Larsson scored and Mike Smith turned aside 47 shots for Phoenix, which began a five-game road trip.

Selected with the 17th overall pick in the 2012 draft, Hertl wasted little time getting in the goal column after registering an assist in his NHL debut. Hertl received the puck in the neutral zone and skated between two defenders in the slot before putting a backhander between Smith's pads 46 seconds into the contest.

Hertl doubled the lead at 7:23 of the first period, deflecting defenseman Matt Irwin's shot from the right point past Smith during a power play.

Marleau converted a man-advantage opportunity 5:07 later, beating Smith from the doorstep after receiving a nifty pass from the left side by Vlasic to make it 3-0.

The Coyotes got on the board late in the second period as Ekman-Larsson began a rush from his own zone and beat a screened Niemi with a wrist shot from the right faceoff circle. Couture sealed the victory for San Jose by scoring into an empty net in the final minute of the third.
