Tennis: Djokovic's blushes spared by Serbian heroine Ivanovic
Djokovic lost in straight sets to Tomic and Serbia had to rely on Ana Ivanovic to beat Ashleigh Barty before edging to a 2-1 win in a tight mixed doubles rubber.
Tomic never really looked in trouble against the world No 1 and an upset in Group A looked on the cards. But Ivanovic made short work of her young opponent and eased to a 6-2 6-3 victory.
Davydenko, ranked 44th in the world, has struggled in recent years with injury, but is targeting a place in the top 20 this year.
