The Islanders' forward has been one of the United States best players in the tournament and his two-goal performance on Sunday helped the Americans clinch a spot in the quarterfinals. Nelson's first goal came at the 4:17 mark of the first period to put Team USA ahead 1-0.
Nelson's second goal came with 3:28 left in the period and the Americans on a power play. Mike Reilly sent a pass to Justin Faulk at the point and Faulk fired the puck at the net. Nelson was in front to grab the rebound and give the United States a 2-0 lead.
The United States went on to win 3-1. It was another strong effort from the Islanders' forward, who had a strong NHL season in 2014-15. In six tournament games for the Americans, Nelson has scored six goals and three assists for nine points. He is tied for the tournament lead in goals, leads his team in scoring and is tied for second in the tournament in scoring.
"Brock's a big strong guy and he was really good around the net tonight," Los Angeles Kings forward Trevor Lewis told the Associated Press.
Nelson credited the chemistry he has had with his line mates for his success in the tournament.
"Our line has been working well for quite a few games now," Nelson said to IIHF.com. "I don't know what the secret is - it would be nice if we did - but I think we've played well from the get-go to create chances and capitalize on them. When you get a few early goals you build that chemistry."
