Bart Swings won the men's mass start speed skating event on Saturday to give Belgium its first Winter Olympic gold medal since 1948.
The final stretch was as close as they come with the difference between first and fourth place at 0.09 seconds.
Joey Mantia of the United States wound up with the first spot off the podium after a photo finish with bronze medalist Lee Seung-Hoon of South Korea. Lee grabbed third place by the tip of his skate, 0.001 seconds ahead of the American.
South Korean Chung Jae-Won earned the silver medal.
Mantia tripped on the final turn, which threw him off slightly. He battled back into the race and said afterward that he believed he was held back at the finish. There was contact between multiple skaters over the final few dozen meters.
The 36-year-old fought through back issues to contend on Saturday. He previously raced in the men's 1500m and team pursuit, finishing sixth and third in those events, respectively. He missed the men's 1000m to rest his back for the mass start.
Ian Quinn, the second American in the competition, was unable to advance past the semifinal. He did not attempt to grab sprint points, betting on himself to finish high enough to move on automatically. The decision backfired as he finished in eighth place and slid to 13th of 15 skaters after points were added up.
Sven Kramer competed in his final career Olympic race for the Netherlands. The 35-year-old will retire with the most speed skating Olympic medals by a man in the sport's long history, earning nine since 2006. He collected multiple medals at each of the last four Winter Olympics but leaves the 2022 Games emptyhanded.
He reached the final on Saturday and finished 16th.
