Roger Federer restored order with his 60th victory at the French Open to reach the third round.
When Federer and Argentina's Diego Sebastian Schwartzman took to Court Suzanne Lenglen, the crowd were still reeling from Serena Williams' shock exit at the hands of Garbine Muguruza.
Coupled with Federer's countryman Stan Wawrinka and his fellow Australian Open champion Li Na both losing in the first round, there was no doubt the tennis world had been rocked significantly off its axis.
Schwartzman, a qualifier playing in the main draw of a grand slam for the first time, hinted at more drama to come when he broke the Federer serve in the third game but the 17-time grand slam champion hit back swiftly to win 6-3 6-4 6-4.
From 2-1 down, Federer won four games in a row and a single break of serve in the second and third sets proved enough, although 21-year-old Schwartzman played a very good match.
In the third round Federer will play 31st seed Dmitry Tursunov, who beat American Sam Querrey 6-4 7-5 6-1.
