This Week’s ATP tennis action at Munich, Estoril and Istanbul is now getting down to the business end of the tournament and the quarter-final line ups are now complete. At Munich top-seed and defending champion faces compatriot Struff for the fourth time today, which were all on clay, and Zverev leads the head to head 4-0 and is favourite to progress. The match could be closer than the odds suggest however, as their last two meetings at Monte Carlo recently and at the quarter final stage at Munich last year were both close three set encounters and there’s nothing to suggest a similar outcome won’t occur again, and on a personal note it would be fair to see Struff finally get a much-deserved win over his compatriot.

Second seed Bautista Agut faces sixth seed Kohlschreiber (13/1) today and the Spaniard leads the head-to-head 2-1 with his two wins coming back in 2015 at Moscow indoors and on clay at Monte Carlo, which was close ending 6-7 6-3 7-6. If you’ve backed Kohlschreiber for the tournament I would consider hedging your bets by laying him on the exchanges or by backing Bautista Agut as their odds are equal.

Fourth seed Chung looked backed to his best winning his opener against Wild Card German Bachinger 6-1 6-1 and he faces qualifier Klizan (26/1) today. Chung leads the head-to-head 1-0, which he won in three sets 6-4 3-6 6-2 at the quarter-final stage at Munich last year. If you’ve backed Klizan it’s a good time to consider hedging your outright stake at least. The one remaining match is between the talented Hungarian Fuscovic and talented young German Marterer, who are both unseeded, and the head-to-head stands at 1-1. Fuscovic won their first meeting on hard courts 3-6 7-6 7-6 back in 2015 and Marterer more recently at the Miami Masters in straight sets 6-4 6-4.

At Estoril its been a bad week for seeded players with only second seed Carreno-Busta and third seed Edmunds (10/1) left standing, after top-seed Anderson lost yesterday against the talented NextGen star Tsitsipas from Greece 6-7 6-3 6-3, who reached the Barcelona final as a qualifier on Sunday and has won ten of his last twelve matches on clay. Second seed Carreno-Busta faces the unseeded and talented Chilean Jarry today for the first time, and third seed Edmunds will play the one remaining Portuguese player Joao Sousa, who is unseeded, and the head-to-head stands at 1-1. Edmunds won their first meeting on clay at the Monte Carlo Masters last year in straight sets, Sousa gained revenge later that year beating him in three sets at the Cincinnati Masters and while Edmunds is the hot favourite to win I thin its prudent to at least cover you outright stake on him as Sousa is the outsider around 2/1.

Britain’s Cameron Norrie wasted a great chance to reach the quarter-final at Estoril yesterday after he lead another unseeded player Carballes Baena by a break in the deciding set, but eventually lost it on a tie break. Carballes Baena will now face Tsitsipas today for the first time and the young Greek star is the hot favourite to progress to the semi-finals. The remaining quarter-final is between Italian veteran and qualifier Bolleli and American NextGen star Tiafoe and this will be there first meeting and given Bolleli’s experience, especially on clay, I think he may just edge this one.

Istanbul has not been a happy hunting ground for seeded players this year with top-seed Cilic crashing out yesterday against the in-form veteran Jaziri in straight sets, second-seed Dzhumur lost against Fabbiano in three sets, third seed Seppi lost against the out of form Serbian Djere in three sets and sixth seed Troicki was thrashed 6-2 6-3 by the unseeded and experienced Brazilian veteran Dutra Silva. The only remaining seeded players at Istanbul are veteran fifth seed Lorenzi, who faces Djere today for the sixth time and the Serbian leads the head-to-head 3-2. They’ve both won two matches on clay between 2015 and 2017 and Djere won their last encounter indoors at Moscow last year and I think he may extend his winning record against Lorenzi today given that he’s beaten him twice on clay in the past.

Seventh seed Vesely has finally began to show some better form this week and that will be tested today against the in-form veteran Jaziri. Vesely leads the head-to-head 2-0, both wins came on clay in straight sets back in 2015 and I expect that trend could continue today, but maybe not in straight sets. The other two quarter-finals are between unseeded players Chardy (13/1) and Italian Fabbiano, who are playing each other for the first time, and again its worth considering hedging your outright stakes on Chardy as Fabbiano is the outsider at over 2/1. Finally, the other quarter final is between two unseeded players, veteran Dutra
