HERNING, Denmark — After a goalless opening period, the United States went on to secure its place in the quarterfinals of the ice hockey world championship with a 6-1 rout of Kazakhstan on Sunday.

The Americans are tied atop Group B with the Czech Republic on 14 points, one more than Switzerland. The already qualified Czechs and Swiss have two more games to play in the preliminary round. The U.S. completes the group stage against the Czechs on Tuesday.

“I thought we were ready to play out of the gate,” U.S. head coach Ryan Warsofsky said. “We need to continue to build and get ready for what will be a big challenge on Tuesday against the Czechs.”

Despite an unproductive first period in Herning, the U.S. jumped to a commanding five-goal lead in the second.

Frank Nazar broke the deadlock 6:58 into the period with a shot from the left circle above the glove of Sergei Kudryavtsev. The forward added two assists later in the game.

Defenseman Jackson Lacombe wristed a shot from the blue line through heavy traffic to double the lead with 8:14 to go in the second period.

The next two goals came in a span of 58 seconds.

Forward Tage Thompson scored his fifth at the tournament — after receiving a pass from defenseman Zeev Buium — to make it 3-0 with 6:00 left. Matty Beniers increased the advantage to four from the left circle before Michael Kesselring scored with a high shot from a tight angle from the boards 56 seconds before the end of the period.

U.S. defensive star Zach Werenski skated toward the goal before beating backup goalie Maxim Pavlenko who came on at the beginning of the final period.

Goaltender Jeremy Swayman made 16 saves for the U.S.

In Stockholm, Austria beat Slovenia 3-2 in a shootout to keep alive its hopes of reaching the quarterfinals for the first time. Austria is tied in fourth with Slovakia in Group A.

The top four teams from each group will advance.

Later Sunday, Switzerland meets Hungary in Herning and Slovakia plays Latvia in Stockholm.

The Minnesota Twins recalled right-hander Zebby Matthews from Triple-A St. Paul and inserted him into the rotation for their road game Sunday against the Milwaukee Brewers.

The 24-year-old Matthews closed out last season in the Twins’ rotation and fashioned a 1-4 record with a 6.69 ERA in nine starts. He has produced a 2-1 record with a 1.93 ERA in seven starts for St. Paul, which includes 38 strikeouts and nine walks over 32⅔ innings.

The Twins, who carry a 13-game winning streak into Sunday’s game, also selected the contract of outfielder Carson McCusker, a 26-year-old who has yet to make his big league debut. The 6-foot-8, 250-pound slugger is hitting .350 with 10 homers and 36 RBIs in 38 games this season for St. Paul.

The task ahead of Matthews is to try to continue a hot pitching streak that has seen the Twins record three straight shutouts, including in the first two games of the Brewers series. Minnesota enters Sunday with a collective 3.15 ERA that ranks No. 3 in the majors.

The active stretch of 33 straight shutout innings is the longest such streak in Twins history, which began in 1961. They had three longer shutout streaks when they were the Washington Senators, but the most recent of those took place in 1913.

To accommodate Matthews’ arrival, the Twins placed reliever Danny Coulombe (left forearm extensor strain) on the 15-day injured list, retroactive to Thursday. Coulombe has yet to allow a run this season in 16⅔ innings.

To make room for McCusker, the Twins shifted rookie Luke Keaschall to the 60-day IL to open a spot on the 40-man roster. Keaschall fractured his right forearm April 25 against the Los Angeles Angels.
