Madison Keys is keen to show the world it’s her time to shine.
The 7th-seeded American played her third round match on Centre Court Tuesday morning. Keys quickly took the first set 6-3, but 9th-seeded Spanish opponent Carla Suarez Navarro was resurgent in the second. Keys, 21, mustered the strength to win the match in the final set. Final score: 6-3, 3-6, 6-3.
It was the second consecutive Keys match to go three sets – indicative of her increasingly high-quality opponents, but also that her sometimes-erratic style still has room for improvement. The 27-year-old Suarez Navarro had the upper hand in terms of experience, having competed professionally since 2003; the American turned pro in 2009.
On the men’s side, 12th-seeded Steve Johnson thrived in his second round singles match against Portugal’s Gastao Elias, winning 6-3, 6-4. He also won big alongside countryman Jack Sock in doubles, beating Spain's duo of Roberto Bautista Agut and David Ferrer 6-4, 6-4.
In general, Spain had a rough day. As previously mentioned, strong players Suarez Navarro (in singles) and Bautista Agut/David Ferrer (in doubles) were knocked out of competition. It was an especially bad day for Ferrer, who lost twice: he fell in singles to unseeded Russian opponent Evgeny Donskoy before he was ousted from doubles.
But the most shocking Spanish defeat came in women’s singles. Garbine Muguruza, who reached as high as World No. 2 earlier in 2016 and beat World No. 1 Serena Williams for this year's French Open title, was utterly helpless against Puerto Rico’s Monica Puig.
After crushing Muguruza 6-1, 6-1 in the third round of play, Puig fell on the ground and began crying. It was a massive, emotional upset – one suitable for the Olympics.
