I have come to the conclusion that it is worth ignoring Serena Williams for betting purposes. The theory that she always wins when she reaches the second week of a Slam was well and truly debunked by Roberta Vinci in the US Open and Angelique Kerber in the Australian.

There is very little solid form to go on so chucking a few darts at big prices on the women’s outright could be the way to go. Kiki Bertens played like a Top-10 player in Fed Cup against France on clay, rolling over two decent yardsticks in Kristina Mladenovic and Caroline Garcia. I’m still not sure how she failed to make the final in Rabat although I also backed Irina-Camelia Begu for that tournament and she fell at the first. The Dutchwoman has played well since and I would give her a chance against Kerber first up. Bertens is a tough opponent particularly when her serve is working, and she reached the fourth round at Roland Garros two years ago after coming through qualifying. Her price of 5-2 to upset the German is fair and 300-1 outright is massive.

After that blip in Rabat, Begu has been very consistent with her other defeats on clay this season coming at the hands of Kerber, Simona Halep and Serena Williams. In what looks a wide-open tournament, Serena aside, she is worth an each-way play at 125-1.

Nearer the top of the betting, Carla Suarez Navarro is an interesting contender at 50-1 outright and 14-1 to win the first quarter. The Spaniard seems to be improving all the time and I would fancy her to beat potential round four opponent Victoria Azarenka on clay. Then it would probably be Serena in the quarters although I am hoping the world number one might have gone by then.

If I had to back one of the favourites, it would be Garbine Muguruza who has reached the quarter-finals for the last two years but she did lose to Begu in Madrid and the pair could meet in the last eight.

I will be stunned if Agnieszka Radwanska does not thrash Bojana Jovanovski. The Serb has played just once since losing 1 and 0 to Alize Cornet in the Australian Open (as tipped on here) and their only previous meeting went the way of the world number two for the loss of just one game. Back the Pole to win the first set 6-0 and 6-1, and I would not put you off doing the same for the second set.

Christina McHale has beaten the likes of Karolina Pliskova and Ana Ivanovic on clay this season and she should be far too strong for French wildcard Myrtille Georges so first set 6-0 and 6-1 is the play here too.
