KEY BISCAYNE, Fla. (AP) Seven-time champion Serena Williams overcame some shaky play Wednesday for her 700th career victory, beating Sabine Lisicki 7-6 (4), 1-6, 6-3 to reach the semifinals of the Miami Open.
Williams won despite an unreliable serve, a poor second set and 51 unforced errors. The victory was her 16th in a row on Key Biscayne, where she's the two-time defending champion.
The No. 1-seeded Williams withdrew before the Indian Wells semifinal earlier this month with a right knee injury, but she has won 19 consecutive matches this year.
Williams' opponent Thursday will be the winner of the match Wednesday night between unseeded American Sloane Stephens and No. 3 Simona Halep.
