<human>: Eugenie "Genie" Bouchard (; French: Eugenie Bouchard, pronounced [oZeni buSaR]); born February 25, 1994) is a Canadian professional tennis player. At the 2014 Wimbledon Championships, Bouchard became the first Canadian-born player representing Canada to reach the finals of a Grand Slam in singles, finishing runner-up to Petra Kvitova. She also reached the semifinals of the 2014 Australian Open and 2014 French Open, and won the 2012 Wimbledon girls' title. Following the end of the 2013 WTA Tour, she was named WTA Newcomer of the Year.

Bouchard started the year by playing at the Brisbane International. She was defeated in the first round by Shelby Rogers. At the Sydney International, Bouchard defeated world No. 23 Zhang Shuai in the first round. She then defeated world No. 6 Dominika Cibulkova in straight sets to set up a quarterfinal meeting with world No. 27 Anastasia Pavlyuchenkova, whom she defeated to reach her first semifinal since February 2016. She lost to world No. 10 Johanna Konta. At the Australian Open, Bouchard defeated Louisa Chirico and Peng Shuai in her first two matches, but lost to Coco Vandeweghe in three sets in the third round. She lost in the first round of her next four tournaments, the Mexican Open, Indian Wells Masters, Miami Open and Monterrey Open respectively.  Bouchard made a return to the ITF Pro Circuit for the first time in nearly four years at the ITF 80K in Indian Harbour Beach, but was defeated by Victoria Duval in the quarterfinals. Two weeks later, she lost in the opening round of the Istanbul Cup to Jana Cepelova. In May at the WTA Premier Mandatory Madrid Open, she won her first tour-level match since the Australian Open in January with a victory over Alize Cornet. She then managed to defeat Maria Sharapova in the second round, her first win in five meetings, to set up a match with world No. 2 Angelique Kerber in the third round. Bouchard won the first set and was up 5-0 in the second before Kerber had to retire with a left thigh injury. Her run was ended by world No. 9 Svetlana Kuznetsova in the quarterfinals. At the French Open, she won her first round match over Risa Ozaki but was defeated by Anastasija Sevastova in the second. Bouchard lost in the opening round of the Wimbledon Championships to Carla Suarez Navarro.

In December, it was announced that trial for Bouchard's lawsuit against the USTA (regarding the alleged head injury caused to Bouchard by the slippery surface in a physiotherapy room at the 2015 US Open) would take place in late February 2018, and is expected to last around 10 days.
