LONDON, June 21(Xinhuanet)-- Unheralded Thai Danai Udomchoke won his first ever Grand Slam match to reach the second round at Wimbledon on Tuesday.

After compatriot Paradorn Srichaphan failed, the 23-year-old Danai, ranked 161st in the world, came through qualifying to book his place in the second round with a 5-7, 6-4, 4-6, 6-3 and 8-6 win against Austrian world 78 Stefan Koubek.

He will then clash against 10th seeded Croatian Mario Ancic, last year's semi-finalist, for a spot in the third round.

The win made up for Paradorn's first round defeat to fifth seeded Russian Marat Safin on Monday.

Before Wimbledon, the Davis Cup stalwart had only played six main tour events, losing in the first round of every one apart from a run to the third round in Tokyo in 2001.

In early men's action, British wildcard Andrew Murray crowned his grand slam debut with a 6-4, 6-2, 6-2 victory over George Bastl in the first round.

Bastl is best known for beating seven-times champion Pete Sampras in the American's last trip to Wimbledon in 2002. Enditem
