Shelby Rogers was three wins away from an improbably French Open title last year, reaching the quarterfinals before losing to eventual champion Garbine Muguruza. The 24-year-old American began her bid for this year's title by defeating Marina Erakovic in straight sets, 7-6 (4), 6-4.
Rogers was broken just once and had an 81 percent first-serve percentage. The world No. 49 is now 2-1 against Erakovic.
"There are so many happy memories here for me." said Rogers during an interview with Tennis Channel. "I had my first Grand Slam win here, so many memories, and it's just a really special place for me.
"I love the courts, I love the people, I just love everything here. I'm happy I can compete again this year."
Rogers will face either Marina Lucic-Baroni or Cagla Buyukakcay in the second round.
