DALLAS — The Ottawa Senators selected Brady Tkachuk with the fourth overall pick in the NHL draft on Friday night.

The 18-year-old winger from Scottsdale, Ariz., had eight goals and 23 assists in 40 games during his freshman 2017-18 season at Boston University, helping the school to a Hockey East title while being named to the all-rookie team.

"I'm super happy right now and super excited to celebrate this with my family and friends," Tkachuk said.

Tkachuk was the first of two Senators first-round picks as Ottawa grabbed defenceman Jacob Bernard-Docker from Okotoks of the Alberta Junior Hockey League at No. 26 overall. The Senators originally had the 22nd pick, but traded down, acquiring the No. 26 pick as well as a second-round selection (No. 48) from the New York Rangers.

Tkachuk, the NHL Central Scouting Bureau's No. 2-ranked North American skater, added three goals and six assists to finish fifth in tournament scoring at the 2018 world junior hockey championship for the United States, which won bronze on home soil.

The six-foot-three, 192-pound forward is the son of former NHLer Keith Tkachuk and the brother of current Calgary Flames winger Matthew Tkachuk.

Brady Tkachuk, who is still growing, has both physical and play-making components to his skill set, much like his father and brother. He was impressed with the organization during his visit to Ottawa.

"They're run by great management. There's great facilities. I was super happy leaving there, and that was definitely a spot I wanted to go to."

Keith Tkachuk, the 19th pick in 1990, scored 538 goals and added 527 assists in 1,201 games over 19 NHL seasons with the Winnipeg Jets, Phoenix Coyotes, St. Louis Blues and Atlanta Thrashers.

Matthew Tkachuk, 20, is set to enter his third season with Calgary. The sixth pick in 2016 has 37 goals and 60 assists in 144 career games.
