Brady Tkachuk was named the captain of the 2024 U.S. team for the IIHF men’s world hockey championship on Thursday.

Tkachuk, who is the captain of the Ottawa Senators, will wear the “C” for Team USA when it plays Sweden on Friday in Ostrava, Czechia.

New York Islanders forward Brock Nelson, Chicago Blackhawks defenseman Seth Jones and Columbus Blue Jackets blueliner Zach Werenski will serve as alternate captains for Team USA.

“We’ve got a great leadership group, and, in the end, everyone will have to lead in their own way for us to be successful,” Team USA head coach John Hynes said. “We’re excited about our team and look forward to starting play in the world championship (on Friday).”

Tkachuk, 24, scored a career-high 37 goals to go along with 37 assists in 81 games this season with the Senators.

He will be playing in his first IIHF men’s world championship. He served as captain of the gold medal-winning U.S. team at the 2017 IIHF under-18 men’s world championship.

The Toronto Maple Leafs relieved Sheldon Keefe of head-coaching duties Thursday.

According to a statement from the club, a search for Keefe’s replacement will begin immediately.

“Today’s decision was difficult,” Leafs general manager Brad Treliving said. “Sheldon is an excellent coach and a great man; however, we determined a new voice is needed to help the team push through to reach our ultimate goal. We thank Sheldon for his hard work and dedication to the organization over the last nine years, and wish him and his family all the very best.”

No determination has been made about the rest of Toronto’s coaching staff, which includes assistants Manny Malhotra, Dean Chynoweth and Guy Boucher.

Keefe has two years remaining on a contract extension Treliving signed him to in August, which doesn’t officially kick in until the 2024-25 season.

In a video posted to social media on Thursday, Keefe thanked Maple Leafs’ management past and present and said farewell to the fan base.

“I’m forever grateful for the opportunity to coach the Toronto Maple Leafs,” said Keefe. “It was a dream come true for a boy from Brampton [Ontario]. I didn’t get it done in the playoffs. I didn’t help push our team over the line and deliver. I accept responsibility for that. No excuses. That’s the job. I didn’t get it done. It’s the reality of the business and I accept it. Anyone who suited up for blue and white, I appreciate you. The players and [Leafs’] support staff will drive the team to success. I believe it will win. Leafs Nation, you deserve your Stanley Cup.”

Treliving is scheduled to meet with the media alongside president Brendan Shanahan and Maple Leaf Sports & Entertainment CEO Keith Pelley on Friday.

Keefe was promoted to Toronto’s head-coaching role in November 2019 to replace the fired Mike Babcock. Keefe had previously been coach of the Leafs’ American Hockey League affiliate, the Toronto Marlies, since 2015 and guided them to a Calder Cup championship in 2018.

Through 4½ NHL seasons, Keefe led the Leafs to a 212-97-40 record — with consecutive seasons of 50 or more wins — and playoff appearances in each full campaign. Toronto never found postseason success under Keefe, though, bowing out of the first round in three of the past four seasons, including in this year’s first-round loss to Boston in Game 7 overtime.

That defeat in particular appeared to seal Keefe’s fate. The Leafs were down 3-1 in the series and battled back to force a decisive final contest, but Toronto’s perennial underachievement forced management into making a change.

This is the first major adjustment for Treliving since he joined Toronto’s staff last May. Shanahan had parted ways with former GM Kyle Dubas — who originally hired Keefe to replace Babcock after also bringing Keefe to the organization when he was GM of the Marlies’ prior to that — and introduced Treliving in the role shortly after. Treliving opted to extend Keefe before last season began, touting Keefe’s “clear vision and direction for where the team needs to go.”

Now the hunt for Keefe’s successor will get underway in what could be a busy offseason for the Leafs. Toronto has key skaters including Auston Matthews and William Nylander signed to long-term contracts. They want to capitalize on that core with success right now, particularly in the playoffs. The other pieces of the Leafs’ designated Core Four — Mitch Marner and John Tavares — will be entering the final year of their current deals this season. Both would be eligible to sign extensions in Toronto on July 1.

MILWAUKEE — Milwaukee left-hander Robert Gasser is expected to make his MLB pitching debut Friday when the Brewers take on the St. Louis Cardinals.

Gasser, who turns 25 on May 31, joined the Brewers in the 2022 trade that sent star closer Josh Hader to San Diego.

Gasser was with the team Thursday as the Brewers began their four-game series with the Cardinals, though he hadn’t yet officially been added to the roster.

“This is what everybody dreams of,” Gasser said before Thursday’s game. “I’m going to have family and friends here to watch it. I know they’re all as excited as I am.”

The Brewers acquired Gasser, along with outfielder Eury Pérez and pitcher Dinelson Lamet, when they gave up Hader, who made four of his five career All-Star appearances with Milwaukee.

Gasser is the only player from the Hader trade who remains in the Brewers organization. Lamet was designated for assignment before appearing in a game with the Brewers. Pérez went to Oakland in December 2022 as part of a three-team trade that brought catcher William Contreras to Milwaukee.

Gasser’s bid to open this season on the major league roster ended when he was diagnosed with bone chips in his throwing elbow. He worked his way back from that and says he feels “great” now.

“They were happy with how I was in spring, what I was bringing to the table,” Gasser said. “It was more so just making sure I was sharp when I got back and getting my pitch counts up.”

After working his way back from the injury, Gasser made three starts with Triple-A Nashville and posted an 0-1 record and a 5.25 ERA with 17 strikeouts in 12 innings.

“We told Gass in spring training, even before the injury, that you’re going to pitch in the major leagues, so prepare for your debut,” Brewers manager Pat Murphy said.

Gasser had gone 9-1 with a 3.79 ERA in 26 games with Nashville last season while striking out 166 in 135⅓ innings.

“There’s some swing-and-miss in there,” Murphy said. “There’s a poise. There’s a good repertoire that I think matches up with both righties and lefties.”
