Cilic makes confident start in Chennai title defense

World number 14 Cilic needed an hour and 13 minutes to quell his 104th-ranked opponent.

"I think I played a pretty good match. Most important my service was very good," Cilic told reporters.

Big-serving Cilic breezed through the opening set after breaking Kunitsyn in the third and fifth games and quickly led 3-1 in the second.

"I think he didn't have any breakpoints in the match which shows that I was top of him, especially in the first set," said Cilic, who beat Indian Somdev Devvarman in last year's final.

"In the second I got an early break and I was able to control from there."

Serbian fourth seed Janko Tipsarevic opens his campaign against former world number one Carlos Moya later on Monday.

Swedish world number eight Robin Soderling, the top seed, plays American Robby Ginepri in the first round on Tuesday.
