Juniors
Richardson, at the time living in Issaquah, Washington, [3] made his first international appearance at the 2014 U18 Optimist International Curling Championship, representing Washington State on Team Nicholas Connolly, where they would win bronze, beating Nova Scotia 5–4 in the bronze medal game. [1] [4]
During the 2015–16 season, Richardson was named to be the second of the mixed team representing the United States at the 2016 Winter Youth Olympics, alongside Luc Violette, Cora Farrell, and Cait Flannery. There, they would win the silver medal, losing in the final to Canada's Mary Fay.
For the 2016–17 season, Richardson would join Team Andrew Stopera as the new second, alongside Violette at third, and Graem Fenson at lead. This line-up won the next three United States Junior Championships from 2017 to 2019. [5] [6] Winning Junior Nationals earned them the chance to represent the United States at the World Junior Championships. [3] At the 2017 Worlds, they earned the silver medal when they lost to Lee Ki-jeong's South Korean team in the final. At the 2018 Worlds they made it to the bronze medal match but lost to Team Switzerland. [7] At the Worlds in 2019, their final as Team Stopera, they finished fifth. [8]
Stopera aged out of juniors after the 2018–19 season. The rest of the team decided to stay together and move up one position, with Richardson now being the new third on Team Violette. Their success at the US Junior Championships continued, winning gold for the fourth year in a row. At the 2020 World Championships they finished in seventh place. [9]
Men's
Once Richardson aged out of juniors after the 2019–20 season, he was selected alongside Luc Violette, Jon Harstad, and Chase Sinnett as the USCA's new men's U-25 national team. The U-25 team program, which stands for under 25 years old, was added in 2020 as a new part of the High Performance Program with the intention of bridging the development gap between juniors and men's curling. [10]
Starting in the 2022–23 season, after Harstad leaving competitive curling, Violette, Richardson, and Sinnnett would add skip Daniel Casper to their new rink. In the team's first event together, they went undefeated to win the Gord Carroll Curling Classic. [11] They also reached the final of their next event, the US Open of Curling, where they lost in an extra end to Korey Dropkin. The team next played in the playdowns for the 2023 Winter World University Games where they won all six of their games to win the event. [12] Back on tour, they had three more playoff appearances, reaching the quarterfinals of the Nufloors Penticton Curling Classic and the finals of both the Curling Stadium Contender Series and the Curl Mesabi Classic. In the new year, the team represented the U.S. on home soil at the 2023 Winter World University Games in Saranac Lake, New York. Through the round robin, Casper led his rink to a 6–3 record, taking the third seed in the playoff bracket. In the semifinals, his rink upset Switzerland's Jan Iseli 6–3 to qualify for the championship game. There, they dropped a 5–1 decision to Great Britain's James Craik, earning the silver medal from the event. [13] Continuing their momentum from the season, Team Casper finished 6–1 through the round robin at the 2023 United States Men's Curling Championship, taking the number one seed in the playoffs. [14] In the 1 vs. 2 game, they faced the reigning US men's champion John Shuster rink where they lost 8–5. [15] This put them in the semifinal where they upset Team Dropkin to advance to the national final. They could not take revenge on Shuster in the final, however, dropping the game 8–3 and settling for the silver medal. [16]
Having had their most successful season to date, Team Casper continued their momentum into the 2023–24 season, finishing runner-up at their first event. A month later, at the US Open of Curling, they defeated Team Dropkin to claim their first tour title of the season. [17] They also won the St. Paul Cash Spiel in October, defeating Rich Ruohonen in the event final. The following week, Team Casper competed in their first Grand Slam of Curling event, which they qualified for with the points they accumulated throughout the past season. [18] Playing in the Tier 2 event of the 2023 Tour Challenge, the team finished 2–2 through the round robin, however, earned a playoff berth with a strong last stone draw total. Qualifying as the eighth seeds, Team Casper upset both Jeong Byeong-jin and Mike McEwen in the quarterfinal and semifinal rounds to advance to the final against Yusuke Morozumi. [19] There, the team shot a high 88%, securing a 6–2 victory over the Japanese and a spot in the 2024 Canadian Open in January. [20] Back on tour, the Casper rink went undefeated at the Curl Mesabi Classic until the final where they were stopped by Tanner Horgan. [21] In the new year, they competed in their first Tier 1 Slam, the 2024 Canadian Open where they finished with a 1–3 record. In their lone win, they beat Kevin Koe's Alberta rink in a 9–8 game. [22] The team ended the season at the 2024 United States Men's Curling Championship where they qualified for the playoffs with a 4–3 record. After defeating Wesley Wendling in the 3 vs. 4 game, they lost to the John Shuster rink 7–5 in the semifinal. [23] At the end of the season, Chase Sinnett and Casper announced they would be parting ways, with Aidan Oldenburg joining as their new lead.
Team Casper would again find their success in the 2025–26 curling season, starting the season by finishing second at the 2025 Trentino Curling World Cup, losing to Yannick Schwaller 7–6 in the final. Casper continued their strong start to the season by winning the Grand Slam of Curling Masters Tier 2 event, beating Kevin Koe 4–2 in the final. Their performance over the past two seasons qualified the team for the 2025 United States Olympic Curling Trials. At the Trials, Team Casper would go 4–2 in the round robin and beat the rink led by 2018 Olympic Champion and 5-time Olympian John Shuster in the best-of-three final series, winning the deciding Game 3 by a score of 7–5 after the two sides split the first two games. [24] This win qualified the Casper rink to represent the United States at the 2025 Olympic Qualification Event. The team would go on to win the Qualification Event, finishing 6–1 after round robin play and beating China's Xu Xiaoming 9–4, qualifying for the 2026 Winter Olympics. [25]
