AFP, Wellington :
The top two seeds Venus Williams and Ana Ivanovic were shock first round losers in the WTA Auckland Classic on Tuesday.
Williams, 35, the tournament top seed and defending champion, was beaten in three sets by 18-year-old Russian Daria Kasatkina, while Ivanovic went down in straight sets to British qualifier Naomi Broady.
On a day when the big names struggled, another former world number one Caroline Wozniacki made it through to the second round but with an unconvincing display against the world number 57 Danka Kovinic.
Williams made an uncharacteristic 73 unforced errors against Kasatkina and after battling to take the first set 7-6 in a tiebreak she dropped the next two 3-6, 3-6.
In the third set, Williams opened up a 3-1 lead before losing five straight games to former French Open junior champion Kasatkina.
Broady, who only learned Monday she was in the main draw after coming through the qualifying tournament, fired down 14 aces to overpower Ivanovic 7-5, 6-4, winning the second set and match on a service break.
Tournament third-seed Wozniacki, who was beaten by Williams in the final last year, moved into the second round with a straight sets win over Montenegro’s Kovinic.
