MELBOURNE (Reuters) - Stan Wawrinka has a simple philosophy in the defence of his Australian Open title, no looking back, do not look too far ahead and win seven successive matches.
"I don't compare last year to this year," the 29-year-old Swiss told reporters after he produced a workmanlike performance to overcome Romanian qualifier Marius Copil 7-6(4) 7-6(4) 6-3 in the second round on Thursday.
