Tabitha Peterson

As a junior, Peterson was a four-time state champion curler and won U.S. national junior championships in 2009 and 2010. In 2009, Peterson played third on her junior rink, skipped by Alexandra Carlson. After winning the U.S. junior title, the team would represent the United States at the 2009 World Junior Curling Championships. The team finished the round robin with a 4–5 record, finishing 5th.[2] In 2010, the Carlson rink won another U.S. junior title, sending the team to the 2010 World Junior Curling Championships. At the 2010 World Juniors, the team finished the round robin in a tie for third place with a 6–3 record. The team won their first playoff match against Switzerland's Manuela Siegrist, before losing in the semi-final to Sweden's Anna Hasselborg. That demoted the team to the bronze medal game where they defeated Switzerland again to finish third overall.[3]

After her junior career ended in 2010, Peterson joined the Allison Pottinger rink at lead position. In their first year together, the team lost in the final of the 2011 United States Women's Curling Championship to Patti Lank. The following season, they avenged this loss by beating Cassandra Johnson's rink to win the 2012 United States Women's Curling Championship. This sent the Pottinger team to the 2012 Ford World Women's Curling Championship to represent the U.S. The team finished the round robin at the 2012 Worlds in a tie with Canada's Heather Nedohin for fourth place and a 7–4 record. However, Canada beat the team in the tie-breaker, forcing the U.S. to settle for 5th.[4] The next season, the team won a bronze medal at the 2013 United States Women's Curling Championship. The team found more success in the 2013–14 season. They won one World Curling Tour (WCT) event over the season, the 2013 Kamloops Crown of Curling. Their success on the World Curling Tour gave them enough points to qualify for the 2014 Ford World Women's Curling Championship, following new rules made by the United States Curling Association which based World Championship qualifying on Order of Merit points rather than winning the U.S. Championship. At World's Team Pottinger finished sixth, with a record of 6–5.[5] As for the U.S. Championship that season, the team ended up losing in the final to Nina Spatola.

For the 2014–15 season Peterson joined Nina Roth as lead. At the 2015 National Championship Team Roth finished fifth, just outside of the playoffs.[6] Peterson claimed another World Curling Tour event win at the 2014 Twin Cities Open.[7]

At the 2016 National Championship Peterson played third for skip Jamie Sinclair. The team finished the round robin with a 5–1 record but lost in the page playoff 3v4 game to Cory Christensen's team.[8] The US Champion team, skipped by Erika Brown, added Peterson as alternate for the 2016 World Championships, where the team finished 6th.[9] Also in 2016 Peterson joined with Joe Polo to compete at the United States Mixed Doubles World Trials. They finished with an impressive 9–1 record, earning them a spot at the 2016 World Mixed Doubles Championship in Karlstad, Sweden. Peterson and Polo finished the round robin group play undefeated, losing to Team Russia in the semifinals. In the bronze medal match they defeated Team Scotland 9–7.[10]

For the 2016–17 season Peterson was back played with Roth's women's team, this time as third. Team Roth won the Molson Cash Spiel that year, a WCT event. At the 2017 National Championship they earned a silver medal when they lost to their former teammate Jamie Sinclair in the final.[11] Peterson's team represented the United States at the 2017 Americas Challenge, where they beat Brazil to qualify the U.S. for the 2017 World Championship.[12] Due to the United States Curling Association's point system at the time, they also got to compete at the 2017 World's despite not being the National Champions. At World's Peterson and Team USA finished fifth with a record of 6–5.[13]

At the 2017 US Mixed Doubles Championship Peterson and teammate Joe Polo earned the silver medal losing to the brother and sister duo of Matt and Becca Hamilton in the final. Later in 2017 Peterson and Polo competed at the first United States Mixed Doubles Olympic Trials, where they finished tied for fifth with a record of 3–4.

Just a month before competing at the Mixed Doubles Olympic Trials, Peterson and her women's team defeated Jamie Sinclair's team in a best of three final at the 2017 United States Olympic Curling Trials to earn the right to represent the United States at the 2018 Winter Olympics. At the Olympics, Team Roth finished with a 4–5 record, missing the playoffs.[14] Due to competing at the Olympics, Team Roth opted to skip the 2018 US National Championships.

In 2019 Peterson returned to both the United States Women's Championship and Mixed Doubles Championship. In a repeat of the 2017 National Championship final, Peterson's women's team of Nina Roth, Becca Hamilton, and sister Tara Peterson lost to Jamie Sinclair in the final.[15] At the Mixed Doubles Championship, Peterson and Polo went undefeated through the round robin section of the tournament but ultimately lost in the semifinal to eventual champions Cory Christensen and John Shuster.[16]

Peterson skipped Team Roth during the 2019–20 season as Nina Roth was on maternity leave. At the 2019 Tour Challenge Grand Slam event they had a semifinal finish. At the 2020 United States Women's Championship Peterson earned her second national title and first as skip. In the round robin Team Peterson's only loss came against Jamie Sinclair but they then beat Team Sinclair in the 1 vs. 2 page playoff game and again in the final.[17] As United States Champions Team Peterson would have represented the United States at the 2020 World Women's Curling Championship, but they lost that opportunity when the Championship was cancelled due to the COVID-19 pandemic.[18] They also earned a spot at the final Grand Slam of the season, the Champions Cup,[19] which was also cancelled due to the pandemic. Their qualification will instead carry over to the 2021 Champions Cup.[20]

During the 2020 off-season the team announced that Peterson would remain as skip when Roth returned from maternity leave. Roth will re-join the team as vice-skip at third, with Hamilton moving to second, Tara Peterson to lead, and Geving to alternate.[21]
