The British No 1 and world No 11 beat Eyal Ran of Israel, 6-4, 6-1, and next plays the Italian Stefano Pescosolido in the quarter-finals today.
Henman dropped his serve in the first game, immediately broke back, but was broken again to level the first set at 4-4. However, he won eight of the next nine games to advance - and remains on course to take on Yevgeny Kafelnikov in the final.
At the Compaq Seniors event in Paris, Argentina's Guillermo Vilas beat Bjorn Borg - 20 years after losing to the Swede in the French Open final. Vilas, who at 46 is the oldest player at the Paris tournament, won 6-4, 2-6, 10-7, the last set being decided by a tiebreak.
"Nothing has changed. Maybe you just feel that your half of the court is a little bigger to cover," Vilas said.Reuse content
