COPENHAGEN, Denmark, Feb. 13 -- Top seed Tim Henman of Britain advanced, but No. 2 Vladimir Voltchkov of Belarus was upset Tuesday in first-round action at the Copenhagen Open.
Henman beat Slava Dosedel of the Czech Republic, 6-4, 2-6, 6-1, and Wayne Black of Zimbabwe knocked off Voltchkov, 6-4, 6-2.
The 26-year-old Henman played his first match here since 1996, when he lost to eventual winner Cedric Pioline in the semifinals. Henman, who won two titles last year to snap a two-year drought, opened the season with a semifinal showing at the AAPT Championship and reached the fourth round at the Australian Open.
Voltchkov, a Wimbledon semifinalist, reached the quarterfinals at the Milan Indoors two weeks ago.
Seventh seed Bohdan Ulihrach, who won both his singles matches in the Czech Republic's first round Davis Cup loss to Sweden over the weekend, beat Andrea Gaudenzi of Italy, 6-2, 7-5 in the first round. A finalist at Doha to start the season, Ulihrach improved to 4-0 lifetime against Gaudenzi.
Two-time champion Magnus Gustafsson of Sweden, the oldest player in the draw at 34, beat the youngest, 18-year-old Joachim Johansson, 7-5, 6-2 in a first-round match. Johansson, who was born in the same town -- Lund -- as Gustafsson, is playing in only his third main draw ATP event.
Jan Siemerink of the Netherlands advanced when countryman Raemon Sluiter was forced to retire after the first set due to injury. Siemerink was leading, 7-6 (7-4).
George Bastl of Switzerland beat Israeli qualifier Noam Behr, 6-7 (5-7), 7-6 (7-1), 6-3 and will meet Henman in the second round.
In other matches, American Cecil Mamiit beat Italy's Davide Sanguinetti, 6-2, 5-7, 6-4 and Lars Bursmuller of Germany defeated Swedish qualifier Johan Settergren, 6-4, 7-5.NEWLN:
