Wimbledon 2015: Garbine Muguruza on a roll after sealing Radwanska clash
It is hardly unknown for seeds to be scattered to the Wimbledon wind - and even with an extra week's practice on grass this year, the bottom half of the women's draw soon had an odd look about it.
Caroline Wozniacki's unexpected defeat by Spain's Garbine Muguruza meant that none of the quarter-finalists in that half were even ranked in the world's top 12. None has ever won a Major, either, but now the powerful Muguruza and the more subtle Agnieszka Radwanska have that opportunity.
Muguruza defeated 15th seed Timea Bacsinszky 7-5 6-3 in a match that never really grabbed the No 1 Court crowd.
With neither player ever having gone beyond the second round before, spectators were probably unfamiliar with them and did not appear to favour one or the other.
Bacsinszky's is the more interesting back-story; a tale of a youngster who was pushed too hard by a father living his own dream rather than hers, causing her to fall out of love with the sport two years ago. She worked as a bartender, waitress and kitchen-hand before deciding tennis was not so bad after all.
She has now cut all ties with her Hungarian father, but the three-month break did wonders for her career and from dropping out of the top 250 at the time, she is now No 15.
Spaniard Muguruza, 21-years-old and seeded 20th, worked hard to earn a place in her first Grand Slam semi-final, the first Spanish woman there since Arantxa Sanchez Vicario in 1997.
"I'm surprised that my first semi-finals is on grass," she said. "But I'm playing really well."
The crowd had thinned out further by the time of a more interesting encounter in which Radwanska's experience and finesse proved too much for young American Madison Keys in a 7-6 3-6 6-3 success.
Twice before, Keys - coached by Lindsay Davenport - had lost her opening set and come back to win, but a tight contest of few service breaks proved a bridge too far.
"It was very tight, point by point, and serve was the key," said Radwanska, the beaten finalist in 2012.
Keys made 21 unforced errors to Radwanska's one by the end of the first set tie-break, which the Pole took 7-3 after spurning three set points in the previous game.
The second set went better for Keys as she cut down on the errors and broke through in the eighth game on a net cord for a 5-3 lead, followed by an eighth ace to level the match.
It was the first set dropped by Radwanska, but there was not to be another. She profited from a bad leave by Keys in the eighth game and two errors too many in the ninth and last.
