Wimbledon 2016: Five biggest upsets from Week 1

#2. Stan Wawrinka’s defeat to Juan Martin Del Potro

Wawrinka was sent packing by a resurging Del Petro

World No.4 Stan Wawrinka is probably the best player after the Big Four and has already won two Grand Slams but this year wasn’t one of Wawrinka’s best as apart from a French Open semi-final, his performances have been quite subdued. The Swiss’ opening game of the Wimbledon was against World No. 65 Taylor Fritz, whom he beat in four sets.He then took on the 2009 US Open Champion Juan Martin Del Potro who had recently returned to tennis after a brief hiatus from the sport owing to a wrist injury he suffered in 2014. The Argentine was playing his first Grand Slam since the 2014 Australian Open and had cruised through the first round with a comfortable win over Frenchman Stephane Robert.Wawrinka began well and took the first set 6-3. However, the World No. 165 bounced back and took the second set 6-3. Both players broke twice in the third set but it was Del Potro who won the third set tiebreak before he ousted Wawrinka by clinching the fourth set 6-3. It was Wawrinka’s worst Grand Slam performance since his first round exit at the 2014 French Open. Del Potro’s tournament ended after a four-set loss to 32nd seeded Frenchman Lucas Pouille in the third round.
