Wimbledon, England ? Her 19th consecutive victory at the All England Club already wrapped up, Venus Williams grabbed a seat and watched younger sister Serena win easily to reach the Wimbledon semifinals, too.

Afterward, Venus and Mom, Oracene Price, strolled out of Centre Court arm-in-arm, chatting and laughing.

Five-time champion Venus beat No. 11-seeded Agnieszka Radwanska of Poland, 6-1, 6-2, before two-time champion Serena defeated No. 8 Victoria Azarenka of Belarus 6-2, 6-3, a pair of overwhelming performances Tuesday that moved the siblings closer to another all-in-the-family final at Wimbledon.

If No. 3 Venus gets by No. 1 Dinara Safina of Russia in Thursday’s semifinals, and No. 2 Serena eliminates No. 4 Elena Dementieva of Russia, the siblings would meet Saturday in their second consecutive final at the All England Club and fourth overall.

It also would be the eighth all-Williams Grand Slam championship match; Serena leads, 5-2.

“I would love it to be a Williams final,” Venus said, “and so would she.”

They are competitors, of course, but also form a team in many ways: The sisters are sharing a house during this tournament, practice with each other and have reached the women’s doubles quarterfinals together.

“We’ve got it all figured out at this point,” Venus said.

She is trying to become the first woman since Steffi Graf in 1991-93 to win three consecutive Wimbledon titles; Serena wants to add to the trophies she earned in 2002-03 by beating her sister in the finals.

Serena owns 10 major titles, Venus seven; Safina and Dementieva have zero.

Safina, who lost in the final at three of the previous five Grand Slam events, overcame 15 double-faults and wore down 41st-ranked Sabine Lisicki of Germany, 6-7 (5), 6-4, 6-1. Dementieva, twice a runner-up at major championships and a singles gold medalist at last year’s Beijing Olympics, never was challenged by 43rd-ranked Francesca Schiavone of Italy and won their quarterfinal, 6-2, 6-2.

Asked about her double-fault total, Safina replied with a smile: “15? I thought it was much more. Sometimes even I don’t know what I’m doing with my serve.”

Pistons fire coach Curry

Detroit — First-year coach Michael Curry became the latest Detroit Pistons coach to get the ax as president for basketball operations Joe Dumars fired him Tuesday after watching his team stumble to a sub-.500 record and an embarrassing first-round exit from the playoffs.

Dumars said after that series that Curry would return, but changed his mind by Tuesday.
