Mason made 33 saves, and Ethan Moreau scored in overtime to give the Blue Jackets a 3-2 victory over the Sharks last night and a split of the two-game, season-opening series with the Sharks in Stockholm.

“I think it’s safe to say that he’s probably got his game back to where it was two years ago,’’ Columbus coach Scott Arniel said of Mason. “[Friday] night he got off to a slow start but he was outstanding from that second period on, and tonight all three periods.’’

Joe Thornton’s power-play goal tied it at 2 in the third period, after Swedish-born Kristian Huselius thrilled the crowd when he scored his second of the season on a power play to put the Blue Jackets ahead at the start of the frame.

“It was nice to bounce back and get the win here,’’ Huselius said.

San Jose took the lead with a power-play goal from Devin Setoguchi 2:02 into the game. Rick Nash tied it just over a minute later when his wrist shot beat goalie Antero Niittymaki.

Niittymaki got the start instead of Antti Niemi and made 22 saves. Niemi earned the win in the Sharks’ 3-2 victory Friday in the opener.

There were a lot more empty seats at the 13,500-seat Globen Arena compared with Friday.

“I guess it was more fans here the first game but it felt like it was more noise, and they were more into the game tonight,’’ Huselius said. “We had some good times here.’’

Red Wings 3, Blackhawks 2 — Valtteri Filppula’s second goal snapped a third-period tie, and Detroit spoiled host Chicago’s Stanley Cup banner-raising celebration.

Lightning 5, Thrashers 3 — Steven Stamkos had two goals and an assist to help new Tampa Bay coach Guy Boucher win his NHL debut in the Lightning’s victory over visiting Atlanta.
