New York, Sep 4 - Indian Somdev Devvarman's Grand Slam singles debut ended with a second round loss to German Philipp Kohlschreiber in the US Open tennis tournament at Flushing Meadows here.

The 23rd-seeded Kohlschreiber was given a tough fight by qualifier Somdev, ranked 162, before advancing 6-3, 6-4, 0-6, 6-2 in two hours and 48 minutes here Thursday.

Somdev's loss brought an end to Indian campaign in the singles draw.

However, there was good news in doubles. Sania Mirza progressed to the second round in women's doubles and mixed doubles. Also clearing their first round hurdles were Mahesh Bhupathi in men's doubles and Leander Paes in mixed doubles.

Somdev had a comfortable first-round victory against 110th ranked Portuguese Fredrico Gil. But Kohlschreiber was a much tougher and more experienced opponent. The German has been in good form this season, having shocked World No 4 Novak Djokovic in the French Open and taking a set off Roger Federer in Wimbledon third round.

The 24-year-old Indian, however, had his chances against Kohlschreiber. Somdev had 20 break point opportunities in the match, but could convert only four. Three of his breaks came in the third set when he blanked Kohlschreiber.

Kohlschreiber broke Somdev twice in the first set even as the Indian wasted four of his five break point chances.

The German took the second set with a break of serve before Somdev came out firing and raced through the third set in just 29 minutes.

Kohlschreiber used all his experience to recover from the setback and wrap up the match in the next set, breaking Somdev twice.

Somdev, winner of back-to-back US collegiate titles, said the experience of playing at this level will put him in good stead.
