Juan Martin del Potro, who recently announced he will play at the Brisbane International, will also plat at the Apia International Sydney, where he is the defending champion.
“I love playing in Sydney. The city and the fans are great and I can’t wait to come back and defend my title,” said del Potro, who has not played competitively since 25 February.
“Last year I played some of my best tennis there and it is the perfect way to start the year. I am looking forward to being back in Sydney as it is one of my favourite cities to play. I remember there were a lot of Argentine fans who came out to support me which was amazing.”
Del Potro will compete alongside Fabio Fognini, David Goffin, Philipp Kohlschreiber, Julien Benneteau, Nicolas Almagro, Leonardo Mayer, Jeremy Chardy, Pablo Cuevas, Nick Kyrgios and 2013 champion Bernard Tomic.
Apia International Sydney Tournament Director Alistair MacDonald said, “We have made multiple changes to our event in 2015 and are thrilled we are able to complement these with another world class line-up of stars.
“We’ll be welcoming back one of the most popular players we’ve ever had in defending champion Juan Martin del Potro and our women’s field this year is one of the strongest you will see outside a Grand Slam.
“To have Australia’s own rising star Nick Kyrgios, one of the most talked about players on tour at the moment, as well as Sydney favourites Bernard Tomic and Sam Stosur is another coup.”
