Serena Williams set up a third Wimbledon final against her older sister by beating Zheng Jie 6-2, 7-6 (5) Thursday.
The two-time major champion had little trouble in the first set against her 133rd-ranked Chinese opponent, who became the first player from her country to reach the semifinals of a Grand Slam tournament.
In Saturday's final, Serena will again face Venus Williams, a four-time Wimbledon champion who lost to her younger sister in the 2002 and '03 finals.
