Sprong was originally selected by the Pittsburgh Penguins in the second round (46th overall) of the 2015 NHL entry draft after playing two seasons with the Charlottetown Islanders of the Quebec Major Junior Hockey League (QMJHL), and made the Penguins immediately after being drafted, though he would return to the QMJHL and play two more seasons with the Islanders.

After his initial stint with the Kraken, he had tenures with the Detroit Red Wings and Vancouver Canucks before returning to Seattle.

Due to the lack of a developed hockey program in the Netherlands, at ages four and five, Sprong played on teams with players as old as twelve or thirteen.

[4] He led the Islanders in scoring with 68 points in 67 games and his outstanding play was recognized when he was named to the 2013–14 QMJHL All-Rookie Team.

[13][14] Sprong led the Islanders in scoring with 20 points in 12 games as the team lost in the third round of the playoffs, ending his junior career.

[20] Sprong played 18 games for the Penguins, scoring two goals, before the team decided to send him back to Charlottetown for the remainder of the season.

[22] During a practice in the playoffs, Sprong injured his shoulder; the subsequent surgery and healing meant he would be unable to play again for roughly 7–8 months.

After a sub-par training camp with the Ducks, Sprong was placed on waivers prior to the 2019–20 season and upon going unclaimed was reassigned to the San Diego Gulls.

Approaching the 2022–23 season, he rejoined the Kraken in signing a professional tryout contract to attend training camp.

[32] To start the season, Sprong was unable to cement a defined role amongst the Canucks forward ranks, appearing in 9 games and registering 1 goal and 3 points.

On November 8, 2024, Sprong's brief tenure with the Canucks concluded after he was traded in a return to the Seattle Kraken in exchange for future considerations.

[37] In 2023, racing driver Zachary Claman DeMelo accused Sprong of assaulting him at a nightclub during the Detroit Grand Prix weekend.
