The Biggest Upsets (So Far) at This Year’s U.S. Open
Though the 2018 U.S. Open Tennis Tournament is just kicking off its quarterfinal matches, this year’s tourney has already featured many high-profile upsets (the biggest one being the scorching temperatures).
Let’s check out some of the most unexpected victories–and losses–so far.
Phillipp Kohlschreiber over  Alexander Zverev – Round 3
The first major upset in the men’s bracket happened in a match between two German players, where Phillipp Kohlschreiber beat Alexander Zverev convincingly in four sets. Kohlschreiber’s victory was just the second time in his career that he was able to beat a top-5 ranked player in a major tournament. The 33-year-old German went on to lose to Kei Nishikori in straight sets in the fourth round, but his upset of the number four ranked player in the world will surely be a feather in his cap for years to come.
John Millman over  Roger Federer – Round 3
Alexander Zverev wasn’t the only top-five ranked player to be ousted in the third round, as Roger Federer fell to Australian John Millman in dramatic fashion. Federer won the first set 6-3 before dropping three straight sets, which ended his tournament early. The loss to Millman was Federer’s first career loss to an unranked opponent at the U.S. Open in his career. The number two ranked player had won his previous 40 matches against unranked players at the Open prior to this year.
Lesia Tusrenko over  Caroline Wozniacki – Round 2
The women’s side of the bracket has been even trickier than the men’s for the top-five ranked players, as three of the top four players in the world have already been eliminated. The first, and perhaps most impressive, upset came in the second round as Ukrainian Lesia Tusrenko vanquished Caroline Wozniacki in two sets, winning 6-4, 6-2. The 29-year-old was able to follow-up on her surprising upset victory by making it to the quarterfinals before finally losing to Naomi Osaka.

 Dominika Cibulkova over  Angelique Kerber – Round 3
This year’s Wimbledon Winner, Angelique Kerber, looked like she was going to cruise to the quarterfinals after dominating the opening set against Dominika Cibulkova by the score of 6-3. The 30-year-old German began to falter quickly after the first set, however, and she was brushed aside by Cibulkova in the second and third sets, losing both by the score of 6-3. The loss will be a gigantic disappointment for Kerber, who’s been knocked out in the first and third rounds respectively in the U.S. Open after winning the event back in 2016.
 Anastasija Sevastova over  Sloane Stephens – Quarterfinals
The final upset that we’ll cover in this piece surrounds third-ranked Sloane Stephens, who won her first ever Grand Slam event in this exact tournament last year. The 25-year-old American has had an up-and-down campaign in 2018, making the finals of the French Open but losing in the first round in the Australian Open and at Wimbledon. Stephens was brushed aside easily on Tuesday, 6-2, 6-3, by Latvian Anastasija Sevastova, whom Stephens beat in the quarterfinals en route to her 2017 title.
With Stephens’ early exit, the United States has just two players left in either side of the tournament. American tennis fans’ hope rests with the 14th ranked Madison Keys and 26th ranked Serena Williams. Keys reached the finals of the U.S. Open last year before losing to Stephens, while Williams is among the favorites to take home the trophy given the fact that she’s won the event six times already in her 23-year career.
