WIMBLEDON, England - One prematch glance Tuesday at the data displayed on those fancy, new digital scoreboards at staid, old Wimbledon provided a pretty persuasive case for why Venus Williams might be considered the woman to beat.
The entry under career record at the grass-court Grand Slam: '55-7.' The listing of her best result: 'WINNER 2007, 2005, 2001, 2000.'
Yet another reason to like the American's chances: The way she served during the ensuing 6-4, 6-3 quarterfinal victory over Tamarine Tanasugarn - smacking eight aces, saving nine of the 10 break points, tying her Wimbledon record with a 127 mph delivery.
That extended Williams' winning streak at the All England Club to 12 matches, including 19 sets in a row. Nonetheless, at least one person who knows a thing or two about tennis and a thing or two about Venus Williams flatly rejected the notion that she's the favorite: Serena Williams.
Asked after her own impressive quarterfinal victory - 6-4, 6-0 against 11th-ranked Agnieszka Radwanska - whether her older sister should be considered the likeliest champion, Serena shot back: 'I would never sit here and say she's the favorite when I'm still in the draw. What are you on?'
Rather than a sibling rivalry, that response perhaps reflects nothing more than the sort of competitive drive that helped the younger Williams win eight Grand Slam singles titles. That haul includes the 2002 and 2003 Wimbledon championships, each time concluded by beating her sister.
One more win apiece, and they'll reprise the all-in-the-family final tradition Saturday. In Thursday's semifinals, Serena will face 133rd-ranked Zheng Jie, who became the first Chinese player to reach the semifinals at a major tournament by upsetting 18th-seeded Nicole Vaidisova 6-2, 5-7, 6-1.
Venus next plays the highest-seeded remaining woman, No. 5 Elena Dementieva, who beat No. 21 Nadia Petrova 6-1, 6-7 (6), 6-3.
Zheng is the first wild-card entrant to reach the women's semifinals at Wimbledon; only one woman ranked lower has made the semifinals at any Grand Slam.
'I just try my best to keep going,' Zheng said.
'China has quite a lot of sports in which it is a world leader,' she said through a translator. 'Unfortunately, tennis is not one of them.'
Like Zheng, Radwanska and Tanasugarn were playing in the Wimbledon quarterfinals for the first time. Unlike her, they were forced to deal with a Williams on Tuesday.
More specifically, they were forced to deal with those Williams serves, developed by Dad all those years ago on the courts in Compton, Calif.
'We're different,' Venus said. 'I serve big almost every time. She goes for a little more placement.'
Against Radwanska, Serena hit 11 aces, including four in one game while pulling even at 3-3 in the first set. On the last of those, Radwanska lunged and whiffed, then grimaced at her racket.
'It's too much, you know,' Radwanska said.
She isn't exactly a nobody, having won the Wimbledon junior title in 2005 and pulled off an upset of defending champion Maria Sharapova at last year's U.S. Open. But Serena made her look absolutely ordinary, if that, taking 28 of the last 37 points.
While Serena mixed in flat 120 mph serves with spinning, kicking changeups, Venus stuck with the hard stuff against Tanasugarn.
'I have a lot of power, so it helps,' Venus said. 'Definitely, the power helps.'
