CHENNAI, India (AFP) – Top seed Stanislas Wawrinka opened his campaign in the new season with a 6-1, 6-4 demolition of teenager Borna Coric of Croatia to cruise into the ATP Chennai Open quarter-finals on Wednesday.
The Swiss world number four gave the 18-year-old Coric a tennis lesson as he began the defence of his title in the $450,000 event on the centre court of the Numgambakkam Tennis Centre.
Wawrinka, who was among the top four seeds given a bye into the second round, showed no signs of rustiness against the 95th-ranked Croatian, the youngest player in the top 100.
Wawrinka will next play eighth seed Gilles Muller of Luxembourg for a place in the semi-finals.
Fourth seed David Goffin of Belgium overcame a mid-match loss of form to struggle past Richardas Berankis of Lithuania in three sets 6-0, 4-6, 7-6 (7/1).
