PERTH, Australia -- Milos Raonic will team up with Eugenie Bouchard for Canada at the 2014 Hopman Cup, the annual international mixed team tennis tournament.
"I think Hopman Cup is a great way to start the year. You have a lot of guaranteed matches, a lot of opportunities to find your way especially after the off season," Raonic said. "It gives you a chance to really get match sharp. It's a great competitive atmosphere, a team atmosphere, something different and something I haven't been involved in."
Under the competition format, eight teams are split into two groups for matches including men's and women's singles and mixed doubles. The winners of each round-robin group advance to a final.
Sloane Stephens will join former champion John Isner on the U.S. team.
The 20-year-old Stephens, who upset Serena Williams in the Australian Open quarterfinals to start 2013, has improved 26 places in the rankings to No. 12 this year.
Isner won the 2011 Hopman Cup with Bethanie Mattek-Sands and combined with Venus Williams for the 2013 edition.
Petra Kvitova, the 2011 Wimbledon champion who won the 2012 Hopman Cup with Tomas Berdych, will be joined on the Czech team by veteran Radesk Stepanek for the Dec. 28-Jan. 4 event.
Anabel Medina Garrigues helped Spain win the title last year and is returning for the defence, when she'll be partnered by two-time Hopman Cup champion Tommy Robredo.
Former U.S. Open champion Sam Stosur and Bernard Tomic will represent Australia, while Jo-Wilfried Tsonga and Alize Cornet will play for France.
Poland will make its debut in the tournament with a team containing No. 4-ranked Agnieszka Radwanska and Wimbledon semifinalist Jerzy Janowicz.
U.S. Open semifinalist Andreas Seppi will join Flavia Pennetta in the Italian team.
