Venus Williams has been beaten in the second round of the China Open by Ana Ivanovic.
Williams, who won the Wuhan Open on Saturday, will not make it back-to-back tournament victories after going down 7-6[3] 6-2 in just over an hour and a half.
The pair exchanged a break each in the first set, with Ivanovic winning the tie-break before Williams capitulated in the second set.
The veteran broke to lead 2-0 but then lost six games on the spin as Ivanovic, of Serbia, romped to victory.
Ivanovic, the sixth seed, will take on 2009 champion Svetlana Kuznetsova in round three.
