SERENA DROPS OUT OF TOURNEY
BRISBANE, Australia — Serena Williams retired during her Hopman Cup match in Perth on Tuesday, completing a day of injuries and upsets for the leading women's players less than two weeks from the Australian Open.
Williams, who missed the U.S. team's opening loss to Ukraine on Monday because of inflammation in her left knee, was trailing 7-5, 2-1 against Jarmila Wolfe when she left the court in her first match of the season.
"I just have some inflammation that's been going away very slowly," Williams said. "It's going away, but just needs a little more time.
"I've been training really hard during the offseason. Really pushing myself beyond the limits. I just think a day off or two will make a world of difference."
Lleyton Hewitt beat Jack Sock 7-5, 6-4, and Hewitt and Wolfe beat Sock and American substitute Victoria Duval 7-6 (7-4), 6-1 in mixed doubles to win the tie 3-0.
QATAR OPEN: Rafael Nadal won his first match of the new season 6-7 (7-5) 6-3, 6-1 against Spanish countryman Pablo Carreno in Doha. Illya Marchenko of Ukraine upset defending champion and fourth-seeded David Ferrer 6-7 (10-8), 6-3, 6-2 for his first career top-10 victory.
Ex-official facing long ban
Sepp Blatter's former right-hand man is facing a nine-year ban from soccer. The FIFA ethics committee's lead investigator, Cornel Borbely, recommended the ban for Jerome Valcke after concluding his inquiry. In his final report, Borbely also asked that Valcke be fined the equivalent of $100,000 and that his 90-day suspension be extended for another 45 days. Valcke, a Frenchman who served alongside Blatter as secretary general for nearly a decade, was accused of violating six articles of the FIFA code of ethics, including confidentiality and conflict of interest.
