Tennis betting recommendation

Question

Victoria Azarenka is a much better player than Gisela Dulko, and I shall consider backing her to win their first round match-up at 1.57

Although one might that expect the RG surface would give Dulko a comparative advantage over the large Belarusian, the kitten-like Argentine is 0-4 this clay court season

It may be worth using a bookmaker than voids bets on incomplete matches, as Aza has retired injured at least twice in the last 6 weeks
