Seeds sent packing in Chennai

Tomas Berdych, Marin Cilic and Stanislas Wawrinka were all sent packing from the ATP Chennai Open at the quarter-final stage on Friday.

World No.6 and top-seed Berdych, playing just has second match of 2013, completed a day of surprises inside the Nungambakkam tennis stadium when he went down 7-5 2-6 6-3 to unheralded Spaniard Roberto Agut.

The 24-year-old Agut, one of the 13 Spaniards to finish in the top-100 last year, showed no signs of nerves as he served and volleyed superbly to beat the tournament favourite in two hours and 17 minutes.

"This is of course my biggest win on the tour," said Agut, who was playing in only his second ATP quarter-final. "I am happy to make such a good start in the first week of the season."

Earlier Cilic, a two-time Chennai champion, was stunned by the 47th-ranked Benoit Paire of France, who prevailed 6-4 1-6 7-5 and will meet Agut on Saturday for a place in the final.

Fourth seed Wawrinka was waylaid by 23-year-old Aljaz Bedene of Slovenia, who advanced to his first-ever ATP semi-final courtesy of a 6-2 7-6 (8/6) win in an hour and 31 minutes.

Bedene's reward is a last four showdown with Serbia's Janko Tipsarevic, the only seeded player to triumph during Friday's quarter-finals.

Tipsarevic, who lost last year's final to Canada's Milos Raonic, overcame Japan's Go Soeda of Japan 6-2 6-4.
