The No. 2 seeded Gwiazdowski got two take downs, clinching the match with the second with less than half a minute left.
Nelson beat Gwiazdowski 1-0 earlier in the year and after a scoreless first period this time, Nelson was able to stay on top of Gwiazdowski the entire second period to score one point and got a second point for riding time.
Gwiazdowski started the final period on his feet, rather than the bottom position that cost him in the second period. He was able to take Nelson down at the 1:30 mark. Following an injury timeout for Nelson, who tweaked an ankle, Gwiadzdowski got that second take down near the end to win it.
