As Boris Johnson could also say right now, this was not how things were supposed to turn out. I know all tipsters have bad runs and I am certainly experiencing one now. There have been some near misses but a few of my tips have been well off the mark.

Thank goodness for Angelique Kerber and Bernard Tomic (apart from nearly giving me a coronary in the first round) who are still going strong for quarter and outright bets, especially Kerber with Garbine Muguruza crashing out most unexpectedly. But we are having more than some difficulty in matches. All we can do is hope our luck changes and quickly.

The pick of the remaining second round matches sees former US Open champion Juan Martin del Potro take on fourth seed Stan Wawrinka. It’s great to see the Argentine back playing well after years of wrist issues and I would give him a chance here against Wawrinka who’s never really produced his best on grass. This does have the makings of a minor classic and I think del Potro can come out on top. I’m not sure how much further he can go but he will be right up for this one.

Grigor Dimitrov looks to have found some form at last but he faces a tough test against recent Nottingham winner Steve Johnson. Both men are serving superbly at present so we’ll play for a first set tiebreak in the hope one of these bets finally comes off!

Kiki Bertens almost paid for Christmas and New Year at Roland Garros but she did show us plenty before limping to defeat against Serena Williams in the semis. She takes on Simona Halep in the third round and I think the Dutchwoman can cause another upset here. Halep is clearly playing well but Bertens’ power may be too much for her and I’m siding with the 26th seed.

Elsewhere, Sloane Stephens should surely have too many guns for qualifier Mandy Minella. The American faces tougher challenges ahead but this should be pretty one-sided. Although I did say the same about Muguruza...
