Andy Murray heralded in the changing of the guard in British tennis when he upset sixth seed Tim Henman 6-2, 5-7, 7-6 in the first round of the Swiss Indoors on Wednesday.

Playing their first competitive match, Murray raced into a 4-0 lead in the opening set against an out-of-sorts Henman.

Serving for the set, Murray came back from 0-30 to win it with an ace after 36 minutes.

The 18-year-old Scot, ranked 70 in the world, kept up the pressure against an opponent 13 years his senior in the second set.

After coming back from 3-1 down, Murray served for the match at 5-4 but his nerves let him down.

Showing his greater experience, Henman recovered to win three successive games and the set when the Scot tamely hit a backhand into the net.

The pair remained deadlocked in a high-quality third set until Murray unleashed a series of crunching winners in the tiebreak to clinch it 7-4 for a memorable victory.
