Australia's Bernard Tomic came from a set down to beat Switzerland's Stanislas Wawrinka 4-6, 6-4, 6-3, 6-3 on Friday and give the host nation a 1-0 lead in their Davis Cup World Group playoff.
Wimbledon quarterfinalist Tomic converted 81 percent of his first serves and won all of his second-serve points on the grass court at Royal Sydney Golf Club to close out the opening singles match in 2 hours, 32 minutes.
No. 28-ranked Wawrinka, who is recovering from a foot injury sustained at the U.S. Open, made 14 unforced errors in the loss.
Roger Federer resumes his long-running rivalry with Lleyton Hewitt in the second singles match later Friday.
