How acquired: Selected with No. 3 pick in 2017 NHL Draft
Last season: HIFK (Liiga): 30 GP, 11-12-23
The two-way defenseman, who turned 19 on July 18, played the past two seasons in the top professional league in Finland. In 2017-18, he more than doubled his point, goal and assist totals from 2016-17, when he had 10 points, five goals and five assists.
Heiskanen (6-foot, 170 pounds), who played for Finland at the 2018 PyeongChang Olympics and scored one goal in five games, likely will make his NHL debut this season on the second or third defense pair.
"He is such an elite skater, has breakaway speed, and his shiftiness is pretty elusive," Stars player development coordinator Rich Peverley said. "I saw him play in [Liiga] and the Continental Cup in Sweden, and Miro and [Buffalo Sabres defenseman Rasmus] Dahlin were two of the best defensemen in that tournament, and that was a men's tournament. It shows the special talent that Miro has."
Projected NHL arrival: This season
