Victoria Azarenka has called on WTA chiefs to provide more support for players who return to the tour after having children. Azarenka stepped up her bid to become the first mother to win Wimbledon in 37 years as the former world number one defeated Russian 15th seed Elena Vesnina 6-3, 6-3 in the second round on Wednesday.
