Jason Pominville had his second two-goal game of the season for the Sabres (0-3-1). Jack Eichel and Zemgus Girgensons each had two assists, and Robin Lehner made 23 saves.
"It's frustrating," Pominville said. "We're not getting the results we want. I thought our effort was way better. But we didn't get the two points, and that's what we play for. Every little detail matters. Right now when we make a mistake, it's going in the back of our net. We have to pay more attention to those little details."
The Sharks took a 1-0 lead when Hertl scored on the power play at 2:15 of the first period, tapping in Kevin Labanc's pass.
"We played great, all four lines," said Hertl, who was moved from center on the third line to left wing on the second line. "[Jones] was good. ... We had a lot of chances after big forechecks. That's how we have to play every game. I'm for sure happy for two points because it was really important for us."
Pominville scored at 12:26 of the first to tie it 1-1. He took a pass from Eichel in the slot and beat Jones with a wrist shot inside the left post.
The Sharks regained the lead less than three minutes later when Tierney took a pass from Donskoi and scored from the low slot at 15:11 to make it 2-1.
Pominville scored his second of the night from close range at 6:50 of the second period, taking a pass from Eichel on a 2-on-1 rush and beating Jones to tie it 2-2.
