Plys started curling in 1998 at the age of eleven.[2] He competed at seven Junior National Championships in a row, winning five of them, including four in a row as skip to finish his junior career. This gives him more junior national titles as skip than any other junior male. As US Champion, he competed at four World Junior Championships. In his first, 2006, Plys took ninth place in Jeonju, South Korea. The next year, in 2007, he took fifth place in Eveleth, Minnesota. And finally in 2008, Plys won the gold medal in Ostersund, Sweden.[3] At his final Junior Worlds in 2009 he again medaled, taking the bronze. Plys also competed at the World University Games in 2007, in Pinerolo, Italy, playing second on John Shuster's gold medal team.
Early in his men's career, Plys was twice invited to be alternate on Shuster's team at international events, at the World Championship in 2009 and the 2010 Winter Olympics. At the Olympics, he was called in to skip the team (in place of Shuster) during draw 6 after the US team suffered four losses in a row, and led the team to a 4–3 victory over France after a 10th end steal. Following the Olympics, Plys was drafted onto Tyler George's team, where he threw third rocks (and sometimes fourth). The George team finished as runners-up in the 2011 and 2013 national championships. In 2014, Plys moved to third on Heath McCormick's team, which placed third in the 2014 and 2015 national championships, and second in both the 2017 Olympic Trials (to Shuster) and 2018 national championships.
Team Shuster represented the United States at the 2021 World Men's Curling Championship, which was played in a fan-less bubble in Calgary due to the ongoing COVID-19 pandemic. There, the team led the U.S. to a 10–3 round robin record, in third place.[7] They played Switzerland in the playoffs, in a game which was delayed a day due to some curlers initially testing positive (including Plys himself)[8] for the virus, but later testing negative (it was later revealed that they were all false positives). In the game, Switzerland, skipped by Peter de Cruz, beat the Americans to advance to the semifinals.[9]
