There have already been a number of upsets at Wimbledon which will have undoubtedly scuppered many punters’ bets.

 However, at the time of writing, those spread bettors amongst you who have bought Federer and Nadal in the men’s singles tournament index will be sitting pretty and hoping for a repeat of the last two finals. Federer is attempting to become the first player since William Renshaw in 1886 to win six consecutive men’s singles titles at Wimbledon and he has made it to the semi finals in typically clinical fashion; failing to concede a set in his opening five games. If the best two players in the tournament, as expected, make it to Sunday’s final, then first set games punters are going to have the tricky decision whether to buy or sell the spread. Two years ago, the Swiss maestro steamed ahead with a 6-0 opening set win, which will obviously please sellers. However, last year he just got through a tense first-set tie-break, before winning the epic 5-set contest.

These two have only met in major finals at the French and Wimbledon, but they have done in all of the last five at both venues (before potentially this one). Nadal holds the advantage due to his three Roland Garros wins, but Federer has proved unbeatable on grass in recent years and his winning streak on this surface is now an incredible 64 matches. Sporting Index punters will undoubtedly find it hard to desert the champion, but buyers of Federer in the final win index will be concerned that each time he has faced Nadal in Paris, the defeat has got heavier, whilst each win at Wimbledon has been more difficult. The game looks very difficult to call, but those who like a spread bet will be interested in buying or selling total games in the final. Nadal underlined his dominance on clay last month, with Federer only winning four games, which led to an extremely low final games make-up of 22. Sellers of total games will be concerned that although the three finals at Roland Garros only average 32.3 games, the two at Wimbledon have averaged 46.5, with 52 in last year’s epic. Buyers will be further buoyed by four of the nine sets played between these two in Wimbledon finals going to a tie-break.

It’s the turn of the ladies 24 hours earlier and it looks like we could have another sense of déjà vu in the final, with both of the Williams sisters progressing comfortably to the semis. These two have won six of the last eight titles here and with hotpots such as Sharapova, Ivanovic and Jankovic going out in the early rounds, buyers of either of them in the Sporting Index win index will have been feeling confident for quite some time. Venus holds the best record at Wimbledon, winning four titles compared with her sister’s two. However, the betting public should also be aware that in six grand slam finals between the two, the older sister has only won once (the US Open in 2001). Serena has won both times they’ve met in the final at Wimbledon, which will please those buying her in the match index.

Venus won the title last year, beating French challenger Marion Bartoli 6-4, 6-1, which ironically was very similar to Serena’s last final appearance at the All-England Club, when she was beaten 6-1, 6-4 by Maria Sharapova in 2004. Sellers of total games will be hoping for a repeat of these finals and will be glad to hear that only two of the sisters’ six final meetings have gone to a final set. However, three of the last five Wimbledon finals have gone all the way, two involving Venus, and buyers of total games will be hoping that Saturday’s final is a repeat of the 2005 contest between Venus and Lindsay Davenport. The game was very tight and Williams eventually came out on top after an incredible 4-6, 7-6, 9-7 victory – one of the longest ladies finals ever played at Wimbledon and probably the most volatile spread betting final ever seen.
