As expected, Serena Williams advanced to the semifinals of the 2012 U.S. Open on Wednesday when she defeated Ana Ivanovic in straight sets, 6-1, 6-3.
Williams, who notched 26 winners and 12 aces in the match, will be an overwhelming favorite against No. 10-seed Sara Errani in the semifinals.
The three-time U.S. Open champ hasn't won the tournament since 2008 and blew up on chair umpire Eva Asderaki in the final of last year's U.S. Open after a controversial ruling.
On Wednesday, she continued her dominant form. She has yet to lose a set after five matches in this year's U.S. Open, and she shut out Andrea Hlavackova in the fourth round before meeting Ivanovic in the quarterfinals.
Beyond her 26 winners and 12 aces on Wednesday, Williams won 26 of 29 first serve points (90 percent), five of eight net points (63 percent) and four of six break points (67 percent), via USOpen.org.
Williams now has 41 aces in the 2012 U.S. Open, most among the women. She also ranks first in first serve points won (81 percent), fifth in second serve points won (60 percent) and fifth in break points won (24).
Williams has been flat-out dominant since the French Open. She's gone 24-1 in singles since then, including a Wimbledon title and a gold medal at the 2012 London Olympic Games. Nobody seems to be able to stop her and it's no wonder why she was the favorite coming into the tournament.
Williams is 4-0 in her career against Errani, including a straight-set victory over the Italian in the quarterfinals of the London Games.
