Paris - Second seed Agnieszka Radwanska of Poland defeated Serbia's Bojana Jovanovski 6-0, 6-2 on Monday to ease into the French Open second round.
Radwanska, who was a quarter-finalist in 2013 but lost in the first round to Germany's Annika Beck last year, goes on to face Caroline Garcia of France.
Garcia won the Strasbourg clay court title on Saturday.
Monday's result left Jovanovski, the world number 120, without a win in 2016.
Earlier, Romanian sixth seed Simona Halep, the 2014 runner-up, reached the French Open second round in just 43 minutes.
Halep eased past Japan's Nao Hinbo 6-2, 6-0 and next plays either Zarina Diyas of Kazakhstan or Carina Witthoeft of Germany for a place in the last 32.
