As of January 2015, Lleyton Hewitt announced that he plans to retire after the 2016 Australian Open. He is interested in finishing his majors career by playing in his 20th Australian Open. Playing in the 2016 Open may be an attempt at history and redemption after years of injuries.
In the 2015 Australian Open, Lleyton Hewitt lost in the second round to Benjamin Becker. He lost in five sets after winning the first two sets. In 2015, Hewitt plans to focus primarily on playing in the Davis Cup for Australia and playing at Wimbledon.
It is unlikely that the loss in the Australian Open was the main cause of Hewitt deciding to retire soon, although it may have had something to do with his wanting to play in the 2016 Australian Open. As of January 2015, Hewitt has only reached a grand slam quarterfinal once in the past eight years. Hewitt has also struggled with injuries in recent years, which is likely one of the reasons he plans to retire in 2016. At the same time, ESPN reported in January 2015 that he felt good at present.
Another reason for Hewitt's planned retirement is for the opportunity to take over as Australia's Davis Cup captain, following Pat Rafter's stepping down. Hewitt is optimistic about Australia's chances in the Davis Cup thanks to the emergence of Nick Kyrgios and Bernard Tomic.
