Cathy Overton-Clapham

Overton-Clapham would again return to the Hearts in 2005, but as a third for Jennifer Jones. There at the 2005 Scott Tournament of Hearts, the team won the championship, defeating Jenn Hanna of Ontario in the final. The team would go on to finish fourth at the 2005 World Women's Curling Championship.

Together the team would participate in the 2005 Canadian Olympic Curling Trials, but would finish 5-4 failing to reach the playoffs.

The team returned to the 2006 Scott Tournament of Hearts as Team Canada, but they lost in the final to Kelly Scott of British Columbia. At the 2007 Scotties Tournament of Hearts, the team lost the semi-final. At the 2008 Scotties Tournament of Hearts, Overton-Clapham won another national title.

The Jones team went to the 2009 Scotties Tournament of Hearts as the reigning champions. They again reached the finals where they faced British Columbia and won thanks to a steal of two in the seventh end. The team went on the 2009 World Women's Curling Championship again as the returning championships but were unable to repeat there, losing to Denmark in the bronze medal game.[4]

The team would again participate in the 2009 Canadian Olympic Curling Trials, and with many expecting them to take the championship, disappointed many along with themselves. The team would only win 2 games, tied for second last place, with a 2–5 record.

Returning to the 2010 Scotties Tournament of Hearts again as part of the Jones team and Team Canada, Overton-Clapham won the national title for the third year in a row.[5] The win was Overton-Clapham's 5th Scotties title in total and moved her one off of Colleen Jones in the record book and alongside the legendary Joyce McKee of Saskatchewan and Nova Scotians Mary Anne Arsenault, Nancy Delahunt, and Kim Kelly.[6]

After playing third for Jennifer Jones' rink for many years, this partnership came to an end after the 2009-10 curling season.[7] The Jennifer Jones team decided to replace her with young former Canadian Junior Champion Kaitlyn Lawes, and ousted Overton-Clapham from the team. Later, Overton-Clapham said in an interview that she was blindsided by the team, she was shocked by this judgment but could tell by the Jones team's behaviour that something was up. Overton's admitted her desire to continue curling however, and she stated that she will be returning to the ice with a new team for the 2010–2011 season. Her new team was to consist of Raunora Westcott and Leslie Wilson, who previously played with Manitoba's 2010 provincial champion Jill Thurston, and former Canadian Junior Champion Breanne Meakin.[8]

With her new team Overton-Clapham has a successful start to the 2010-11 curling season. However young third Breanne Meakin qualified for the 2011 Canadian Junior Curling Championships, forcing Overton-Clapham to find a new third for the 2011 Manitoba Scotties Tournament of Hearts.[7] On short notice, Karen Fallis was selected to take Meakin's place and Meakin was slotted in as the team's alternate. So with a new team formed, Overton-Clapham won the provincial championships over Chelsea Carey by a score of 7–4. Overton-Clapham's team played Jennifer Jones' rink in the round-robin at the 2011 Scotties Tournament of Hearts on February 23.[9] Despite a poor start to the 2011 Scotties, the match against Jones was still hyped by media. Overton-Clapham would win the match 8–5, the crowd cheered her every shot, and were chanting "Cathy-O" as the two teams shook hands.[10] The final event the team would play together was the 2011 Players' Championships Grand Slam of Curling event. They would finish 0–3 in a triple knockout format.[11]

Overton-Clapham announced she will once again have a new team for the 2011 season. Her second Leslie Wilson decided she wanted to take a year off from curling and her lead Raunora Westcott was unsure as to what she would do. Karen Fallis, who filled in for Breanne Meakin during the Manitoba Scotties, and played third stones during the 2011 Scotties, skips her own Manitoba team and will not return to the team. Together the Team mutually decided they would part ways. Breanne Meakin will remain with Overton-Clapham, and the two will add two time Canadian Junior Champion Jenna Loder and Ashley Howard, daughter of three time world Champion and 2006 Olympic Gold Medallist Russ Howard, as she will be attending school in Manitoba.[12]

Overton-Clapham's team found early success in the season when they won the first Grand Slam Event, the 2011 Curlers Corner Autumn Gold Curling Classic. Modifying her initial lineup, Loder moved to third, Howard to second and Meakin to lead, the team won the third qualification. In the playoffs Overton-Clapham defeated Stefanie Lawton, Sherry Middaugh and in the final Amy Nixon to win the championship.[13][14]

At the 2012 Players' Championship team Overton-Clapham finished at the top of the standings at the end of the round robin, with a 6–1 record. They went on to defeat Sherry Middaugh in the semifinal and faced Stefanie Lawton in the final. Although the team eventually lost the final to Lawton, their overall performance in Grand Slam events of the season gave them the Capital One Cup for 2012 and a $50,000 prize.[15][16] The team's overall success during the 2011–12 season would also qualify them for a place in the 2012 Canada Cup of Curling and the 2013 Canadian Olympic Curling Pre-Trials. However, on February 1, 2013, Overton-Clapham announced she would be leaving her team and taking a break from the game.[17] She did not take a break for long however, as she moved to Calgary later in the year to play third for the Crystal Webster rink.

Overton-Clapham continued to curl in 2017, joining up with Team Carey consisting of, Chelsea Carey, Jocelyn Peterman and Laine Peters after Amy Nixon stepped away from curling. She had great success throughout the year, she lost the Canadian curling Olympic Trials in 2017 against Rachel Homan. Team Carey went undefeated until losing to Team Homan in the Final 6–4.

She now coaches Team Jamie Sinclair of the United States as of 2019.
