Finland has advanced to its first gold-medal game at the worlds since 2016 with a 1-0 victory over Russia on Saturday.
Kevin Lankinen was sensational in net for Finland, turning aside all 32 shots he faced for his second shutout of the tournament.
Neither goaltender would budge in the defensive affair until Finnish captain Marko Anttila found twine with under 10 minutes to play in what would prove to be the game-winner.
Henri Jokiharju and Joel Kiviranta picked up assists on Antilla's tally.
Andrei Vasilevskiy was solid between the pipes for Russia, allowing just the one goal while making 28 stops in the contest.
Russia will play for bronze for the third time in the last four World Championships after finishing sixth in 2018.
Finland has now won seven of its nine contests and will meet Canada for a chance to win its first gold medal at the worlds since 2011.
