4. Seeds toppled
The Wimbledon Round of 128 saw the most top 10 upsets ever in Grand Slams in the Open Era edition with 7 out of them bowing out.
Dimitrov's defeat to Wawrinka was the least of the surprises in this tournament. David Goffin, who had been impressive this season, was ousted in straight sets by Matthew Ebden in the first round. Dominic Thiem was 2 sets and a break down against Baghdatis when he retired for the tournament.
One of the favorites to win the tournament, and former finalist Marin Cilic, was dominating Guido Pella who was ranked below 70 when play was suspended. What followed the next day was one of the best comebacks I've ever watched, with the Argentine winning the remaining sets to stop Cilic in Round 2.
Another favorite Sasha Zverev bowed out in the 3rd round after being up 2-1 against Ernests Gulbis. The most shocking fact is that he was overpowered by 6 games to love by the unorthodox Frenchman in the final set.
The best upset for me and many people, it was Anderson's quarterfinals victory against Roger Federer. Why? Simply because he didn't have anytime to regroup after being 2 sets down like Pella, his opponent didn't lose steam in the 5th set like Gulbis'. The South African was as assured as a top-flight player and for that reason, it was the best upset indeed.
Sloane Stevens, who's been a hit and miss at the Grand Slams, lost to Vekic. Elina Svitolina bowed out in 3 sets against Belgium's T. Maria. The biggest surprise of Round 1 was Kvitova, one of the contenders for the title losing to Sasnovich in 3 sets with the last set reading 0-6.
The upsets continued in Round 2 as well with No.2 seed Caroline Wozniacki getting knocked out by Makarova in 3 sets after getting the 2nd set 6-1. Defending champion Muguruza too was not spared. She lost to Van Uytvanck in after taking the first set, not to mention that the upset came from a Belgian yet again.
Venus Williams was the first victim of Round 3 although she was sent packing by a seed. No.20 seeded Kiki Bertens showed admirable composure in the 3rd set to take it 8-6 to defeat the veteran. Bertens would go on to upset 7th seeded Karolina Pliskova in the next round. Another American Madison Keys lost to Rodina in 3 sets later in Day 5.
The shock of the tournament was Simona Halep's loss to S-W. Hseih in the 3rd round. The fact that the Romanian had won the French Open earlier, was in great form and was a set ahead in the match makes this the best upset in the Ladies' Draw.
