Green opened up what would end up being the most successful year of his career so far with a 3–1 record at the 2017 World Cup. After that, he went on to start a 20–match win–streak, where he claimed the Ukrainian Memorial International title, the US Open National championship, the Pan American Continental Championship, made his third–straight US World Team and placed himself on top of the Grand Prix of Spain podium before competing at the World Championships, defeating three opponents to make the gold–medal match, where he was derailed by '15 World Champion from Italy Frank Chamizo to claim the silver medal.
