Sharapova, a four-time runner-up, earned another berth in the final by beating Jelena Jankovic 6-2, 6-1 Thursday at the Sony Open. (Getty Images)

Sharapova is 2-11 against Williams, with both of the wins way back in 2004. Williams has won their past 10 meetings and their past 13 sets. (Getty Images)

"They have been pretty quick matches," Sharapova said. "She's a tremendous athlete, has so much power, and a confident player as well. So if you have a few games where you're not stepping in and not playing the way you should be, she takes really good advantage of it." (Getty Images)

Eight hours later, five-time champion Williams advanced when she beat defending champion Agnieszka Radwanska 6-0, 6-3. (Getty Images)

With a victory Saturday, the No. 3-seeded Sharapova would plug one of the few holes in her resume. She completed a career Grand Slam by winning the French Open last year but has never won the tournament near downtown Miami. (Getty Images)
