Serena Williams set a tournament record with 24 aces on Thursday as she defeated Victoria Azarenka 6-3, 7-6 (6) in the 2012 Wimbledon semifinals.
Williams will look for her 14th Grand Slam title when she meets Agnieszka Radwanska in Saturday's final. Radwanska advanced with a 6-3, 6-4 victory against Angelique Kerber in the other semifinal match.
Williams aced Azarenka on match point for the record, her third ace of the second set tiebreaker. She also held the previous record of 23, which she set in the third round against Zheng Jie. Thursday's outing was considerably more impressive, since Williams recorded all her aces in just two sets.
The men's semifinals will be held on Friday. Novak Djokovic meets Roger Federer on one side of the bracket with Jo-Wilfried Tsonga and Andy Murray facing off in the other.
