Andy Roddick maintained his momentum as new world number one by beating Jonas Bjorkman in the Paris Masters quarter-finals.
Bjorkman's 7-5 7-6 (7/0) loss means there will be no Swedish win on the ATP circuit for the first time since 1973.
He battled well before Roddick broke him in the 12th game with two superb backhand passes.
The second set was also close but the tiebreak was a rout.
Roddick hit a total of 19 aces on his way to a semi-final against either Britain's Tim Henman, who upset the odds by beating third seed Roger Federer 7-6 (7/5) 6-1.
Earlier, Andrei Pavel picked the perfect time to rediscover his form as he beat fifth seed Rainer Schuettler 2-6 6-3 6-2.
Pavel missed the first half of this season with a back injury and did not win a match until September.
However, the unseeded Romanian was too strong for Schuettler, who put in a lacklustre performance.
Pavel will next play 14th seed Jiri Novak, who destroyed Hicham Arazi.
Novak is showing the sort of form that took him to the Masters Cup last year.
He followed up his win over top seed Juan Carlos Ferrero in the last round with a 6-2 6-1 thrashing of Arazi.
