Six-time champion Serena Williams has taken the first set 6-0 in her Australian Open singles semifinal against Agnieszka Radwanska.
With the roof closed on Rod Laver Arena because of rain showers in the area, Williams broke Radwanska's service to open the match and was rarely troubled in the 21-minute set.
The No. 4-ranked Radwanska had just one winner in the opening set — a forehand cross-court shot in the fourth game. Williams had 18 winners in the first set.
