Johannesburg, Feb 01 (Agencies): Asian gold medallist Somdev Devvarman has entered into the second round of the ATP South African Open with a straight-set win over  local hope Raven Klaasen in his opening match.

Somdev defeated the local qualifier 6-4 6-3 in his lung-opener of the USD 442,500 event.

The Indian tennis ace faces a tough challenge from here on as his very next opponent could be third seed Serb Janko Tipsarevic, who would be squaring off against  the Netherlands' Jesse Huta in his opening match.

Somdev, who was a quarter-finalist in the event last year, relied on his powerful serve from the very beginning and did not offer a single break chance to his rival in the opening set.

The Indian converted one of the four break points he earned in the first set to nose ahead.
