PHILADELPHIA -- After losing three of four games at home, the San Jose Sharks hit the road for six straight, a stretch in which coach Peter DeBoer called a "gut check."

Well, the team's gut seems to be doing just fine.

The Sharks have now ripped off four consecutive wins on this six-game road swing after beating the Philadelphia Flyers 1-0 in overtime on Thursday night at Wells Fargo Center.

"We needed a good road trip," DeBoer said. "We talked about that, taking it one game at a time and trying to squeeze out wins. We weren't in a great spot after our homestand. To our guys' credit, it was a little bit of a gut check and we're finding a way here."

San Jose won it with 1:15 left in overtime when center Melker Karlsson scored on a 2-on-1 rush off a pass from right winger Joonas Donskoi.

"He chipped it over to me and I don't know," Karlsson said. "I think it almost rolled over my blade but I was lucky it went in."

The Sharks (11-8-0) improved to 8-3-0 away from home and also prolonged their dominance of Philadelphia, winning for the 13th time over the last 14 meetings.

Meanwhile, the Flyers (6-8-5) continued their home futility. Philadelphia hasn't won in its own building since Oct. 24 and has lost 10 of its last 12 overall. In fact, the Flyers' home losing streak is at six games, their longest such skid since March 12-April 3 in 2011, when they also dropped six in a row.

On Tuesday, they lost in a shootout. On Thursday, it was overtime that bit them.

"I think we put together another pretty complete performance out there again," Philadelphia coach Dave Hakstol said. "That's what we have to control and continue to do.

"We were the better team I thought for the last 40, 44 minutes of this hockey game. I thought we were a little bit quicker and did things pretty well during that time frame, so I'm going to take that and keep building."

Sharks goalie Martin Jones made 34 saves to win his fourth straight. He was brilliant and his coach recognized it.

"Over 82 games you have to win all kinds of different ways," DeBoer said. "Tonight was a goalie win for us. You have to get timely contributions at different points from everybody. (Jones) was our best guy tonight."

Flyers goalie Steve Mason was the tough-luck loser and stopped 20 shots. Philadelphia is last in the NHL in goals with 34, forcing Mason to oftentimes be perfect for the Flyers to even stand a chance.

"It's been like that for a good portion of the season," Mason said. "It just puts the emphasis on strong goaltending.

"At the end of the day, when the goals aren't coming for us, you just have to bear down and focus on your own job and my job is stopping the puck."

Why has it been such a struggle for the Flyers, a team that featured four 20-plus goal scorers a season ago?

"It's hard to answer," right winger Jakub Voracek said. "We've got to find a way to be better. I have no answer.

"If we knew, we would work on it. I can't tell you why we don't score a goal."

Sharks left winger Patrick Marleau didn't record a point, keeping him at 999 for his career. Only 82 players in NHL history have accomplished the feat.

It was a slow first period, as the Sharks outshot the Flyers 10-6.

However, Philadelphia came out aggressive in the second, outshooting San Jose 15-5, but Jones kept it off the board. He stoned a wrist shot by left winger Matt Read and denied center Sean Couturier's wraparound attempt shortly after to keep it scoreless.

Both teams saw opportunities on the power play in the third, but failed to put the puck in the back of the net.

That was until 3-on-3 overtime decided things.

"We were on our heels in the second and third," DeBoer said. "Our goalie was our best player and gave us a chance to get two points."
