I'm using the same bookmaker for all players rather than the best odds you can get on any one player, because this isn't about who to put money on. Anyway, here they are:
Men's singles:
1. Roger Federer: 7/4
2. Rafael Nadal: 5/1
3. Novak Djokovic: 11/2
4. Alex Zverev: 10/1
4. Grigor Dimitrov: 10/1
6. Juan Martin Del Potro: 14/1
6. Nick Kyrgios: 14/1
8. David Goffin: 16/1
9. Dominic Thiem: 28/1
9. Stan Wawrinka: 28/1
11. Marin Cilic: 33/1
11. Milos Raonic: 33/1
13. Kevin Anderson: 40/1
14. Gael Monfils: 50/1
14. Jack Sock: 50/1
16. Denis Shapovalov: 66/1
17. Jo-Wilfried Tsonga: 80/1
18. Gilles Simon: 100/1
18. Roberto Bautista-Agut: 100/1
18. Lucas Pouille: 100/1
Women's singles:
1. Garbine Muguruza: 8/1
1. Simona Halep: 8/1
1. Karolina Pliskova: 8/1
4. Elina Svitolina: 9/1
5. Caroline Wozniacki: 11/1
6. Angelique Kerber: 12/1
6. Maria Sharapova: 12/1
8. Julia Goerges: 14/1
9. Petra Kvitova: 18/1
10. Johanna Konta: 20/1
10. Madison Keys: 20/1
12. Ashleigh Barty: 25/1
12. Venus Williams: 25/1
12. Coco Vandeweghe: 25/1
15. Caroline Garcia: 28/1
16. Belinda Bencic: 33/1
16. Jelena Ostapenko: 33/1
18. Dominika Cibulkova: 40/1
18. Kaia Kanepi: 40/1
20. Sloane Stephens: 50/1
20. Anastasija Sevastova: 50/1
I'll confine myself to two comments:
1. Both fields are really open.
2. But the women's odds essentially amount to saying, "Hell if we know who's got this?"
