For her 700th victory, Serena Williams overcame herself before overcoming the opponent.

Williams persevered through 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 and has won seven times overall.

"I know today wasn't my best day," she said. "I just told myself, I'm not serving the way I normally serve and hitting the way I normally would hit, so at this point all I can do is just fight and try to give 200 percent instead of 100 percent."

She improved her record to 700-120.

The No. 1-seeded Williams withdrew before the Indian Wells semifinal earlier this month because of a right knee injury, but she has won 19 consecutive matches this year.

Flat-seam ball produces results

Home runs are up 39 percent in Division I baseball compared with the first half of the 2014 season, an indication the introduction of a flat-seam ball is having the desired effect.

According to the NCAA midseason statistical report, the per-team home-run rate has gone from 0.36 a game to 0.50.

Fifty teams have hit 20 or more home runs. Eighteen teams had hit that many at this point a year ago. Forty-three players have seven or more homers, compared with 19 players through March 2014.
