KEY BISCAYNE, FLA. - A day after her younger sister lost a quarterfinal match, Venus Williams was shown the door in the round of eight at the lucrative Sony Ericsson Open.
Surging fifth-seeded Pole Agnieszka Radwanska handled an unseeded Williams 6-4, 6-1 on the hardcourts at Crandon Park. Radwanska moved on in 80 minutes by breaking Williams' serve a whopping six times.
Radwanska is now 2-5 lifetime against the former world No. 1 and seven-time major champion Williams. The American had won their two previous encounters in Miami in 2009 and 2010.
This marked the 31-year-old Williams' first tournament action since she pulled out of the U.S. Open in the second round last summer, as she's been slowed mightily by Sjogren's syndrome, an incurable autoimmune disease that causes fatigue and joint pain.
The five-time Miami champion Serena Williams lost to fellow former No. 1 Caroline Wozniacki here on Tuesday night.
Radwanska, who titled in Dubai last month, will face the Victoria Azarenka- Marion Bartoli victor in Thursday's semifinals. The Australian Open champion Azarenka has yet to lose this year, at 26-0, and is the reigning Miami champ, having beaten Maria Sharapova in last year's finale. The Belarusian star also titled here in 2009.
Thursday's other semi will pit a second-seeded Sharapova against a fourth- seeded Wozniacki. The former No. 1 and three-time Grand Slam titlist Sharapova is a three-time Miami runner-up.
Sharapova lost to Azarenka in the Indian Wells final two weeks ago and also succumbed to the Belarusian star in this year's Aussie Open finale.
The winner of this $4.828 million event will pocket $712,000.
