Early career
After playing korfball first as a kid, Mast switched to basketball for the club Celeritas-Donar from Groningen. After a couple of years, he changed teams to RTC Noord where he was coached by Marco van den Berg. As a youngster, Mast received offers for Real Madrid Baloncesto to play in their program.

2017–18: Rookie season
Mast played his first professional seasons for Donar, as he was added to the roster for the 2017–18 season. When Mast played his first game, he was 16 years old. On 1 February 2018, Mast scored 24 points in a NBB Cup game against Racing Beverwijk, which made him the youngest top scorer for Donar in history.

He played two games in the continental fourth-tier FIBA Europe Cup competition.

2018–19: Breakthrough season
In the 2018–19 season, Mast had his breakthrough season. Because of personnel changes within Donar and American players leaving, Mast was given a place in the starting five from January. On 12 January, he scored a career-high 30 points in a 101–67 win against BAL Weert. In April 2019, he was awarded the DBL MVP Under 23 award, as well as the DBL Most Improved Player award.

Nebraska
In April 2023, after four years at Bradley, Mast announced that he would be transferring to Nebraska, where he would have two years of eligibility remaining. He explained his move by stating that "Bradley is a great basketball spot, [...] but you get to play against high majors 4-5 times a season. I want to see how I match up and play under bright lights every night. I want to see how I stack up against the best competition in college."

In 2017, Mast played for the under-16 and the under-18 Netherlands national basketball team. He played at the 2017 FIBA Europe Under-16 Championship Division B, where he reached the final and made the tournament All-Star Team. Mast averaged 11.9 points, 10.1 rebounds and 1.4 assists per game.
