Wawrinka falls to Raonic at Open
The 2014 champion Stan Wawrinka was edged out of the Australian Open Thursday by 16th seed Milos Raonic in the tightest of second-round battles.
The Swiss 33-year-old, unseeded for the first time since his debut in 2006 after being plagued by injury, fell to the Canadian after four sets decided on tiebreaks 6-7 (4/7), 7-6 (8/6), 7-6 (13/11), 7-6 (7/5).
Raonic, who got to the Australian Open semi-finals in 2016 before losing to Andy Murray, will face South Korea's Hyung Cheon or Pierre-Hugues Herbert of France in the third round.
