The big question here is if John Isner can continue the great form shown in the first two rounds. He's seeded 20th at Wimbledon and takes on Jannik Sinner who is the 10th seed. Isner is a former top ten player and semi-finalist at Wimbledon. He has one of the best serves in tennis and already served close to 100 aces in this tournament. That's not far off winning 25 games just by aces alone. Serving like that has seen him win two matches this week, including a four-set victory over Andy Murray. He's likely to beat the world record for career aces sometime during this match against Sinner. Isner has had a successful year playing doubles in 2022 and that seems to have improved his volleying too, making him even more of a difficult opponent on grass. The winner of this match faces either Oscar Otte or fifth seeded Carlos Alcaraz in the last 16.
Jannik Sinner has only ever had 10 matches on grass. He's won four of them but two were this week and the others in qualifying matches. Only this week has he had his first main draw win in a grass court tournament. He's the 10th seed but that has been earned by his results on clay and hard courts, not grass. This week has seen him beat Stan Wawrinka and Mikael Ymer to finally get to the third round at Wimbledon. He's dropped sets in both of those victories and although the higher seed, it's Isner who can be backed to get the win here. Have a side bet on there being a tie-break.
