   Five highlights from Day 7 of the French Open in Paris:
   1. No. 6 seed Jo-Wilfried Tsonga, bidding to become the first Frenchman to win Roland Garros since Yannick Noah 33 years ago, retired with a thigh injury while leading Ernests Gulbis of Latvia 5-2 in the third round.
   Tsonga, who had reached the French Open semifinals in two of the past three years, withdrew from the Italian Open earlier this month with the same problem.
   2. Top seeds Novak Djokovic and Serena Williams advanced in straight sets, although Williams struggled.
   Djokovic, attempting to become the eighth man to achieve a career Grand Slam, outclassed Aljaz Bedene of Great Britain 6-2, 6-3, 6-3.
   Williams, trying to tie Steffi Graf for second place with 22 Grand Slam singles titles, subdued No. 26 seed Kristina Mladenovic of France 6-4, 7-6 (10).
   3. No. 18 seed Elina Svitolina of Ukraine eliminated No. 14 Ana Ivanovic, a former French Open champion and a semifinalist last year, 6-4, 6-4.
   The 21-year-old Svitolina, a semifinalist in the Bank of the West Classic at Stanford last August, will face Williams, a three-time Bank of the West champion, in the round of 16.
   Ivanovic won the 2008 French Open to climb to No. 1 in the world. She also reached the 2007 final at Roland Garros, losing to Justine Henin.
   4. Four American women and one U.S. man have reached the singles round of 16.
   Remaining alive on the women's side, in addition to Serena Williams, are No. 9 seed Venus Williams, No. 15 Madison Keys and unseeded Shelby Rogers.
   On the men's side, No. 15 John Isner has matched his career-best result at Roland Garros. The 6-foot-10 (2.08-meter) Isner is scheduled to play No. 2 Andy Murray today. Murray leads the head-to-head series 5-0.
   5. All teenagers have been eliminated in men's and women's singles. Losing in the third round on Saturday were 19-year-olds Alexander Zverev of Germany, Borna Coric of Croatia and Daria Kasatkina, seeded 29th, of Russia. Naomi Osaka, 18, of Japan lost in the third round on Friday.
   The 6-foot-6 (1.98-meter) Zverev is widely considered a future world No. 1.
