Key play: Sami Vatanen scored the only goal the Ducks needed to defeat the Buffalo Sabres 1-0 on Wednesday at the Honda Center for their sixth consecutive victory. Vatanen sent a wrist shot through traffic and into the net at 3:20 of the second period for his ninth goal of the season.

Pivotal performer: Ducks goaltender Frederik Andersen’s last shutout was Jan. 27, 2015, against the Vancouver Canucks. He hadn’t recorded one in 57 games before blanking the Sabres on 26 shots to improve his record to 10-0-1 with a 1.97 goals-against average in his last 11 decisions.

Quote, unquote: “When he’s on, he can make the save that nobody else can make,” Ducks coach Bruce Boudreau said of Andersen, who had his fourth career shutout. “We’ve seen it time and time again. … He’s a big man who is very mobile in the net.”

Streaking captain: Ducks center Ryan Getzlaf’s second-period assist on Vatanen’s power-play goal gave him at least one point in nine consecutive games. He has four goals and 10 assists during the streak pushing his season totals to eight goals and a team-leading 48 points. He set a team record by recording his eighth career 40-assist season, passing Teemu Selanne, who had seven.

Lock-down time: The Ducks went into the game with a 20-0-3 record when leading after two periods. Their flawless mark in regulation play in 2015-16 was put to the test when they took a 1-0 lead into the third period against the Sabres. Make it 21-0-3, though, after they held on to beat Buffalo.
