Angelique Kerber
Germany's Angelique Kerber was knocked out by Russia's Ekaterina Makarova 6-2, 6-2 on Sunday. She became the first top seed in French Open history to lose in the opening round.
Before this year, the earliest exits suffered by a top seed were in the second round -- by Justine Henin in 2004 and Serena Williams in 2014.
Makarova goes on to face either Lesia Tsurenko or Kateryna Kozlova, both of the Ukraine.
