PARIS—Lucie Safarova, who lost to Serena Williams in the French Open final, believes the American could win all four Grand Slam titles this season. The world No. 1 has won three consecutive majors; her last loss at a Slam came in the third round of 2014 Wimbledon to Alize Cornet.
Williams won four consecutive Slams between 2003 and 2004, but has yet to complete the Grand Slam in a calendar year. “She's a great player,” Safarova said. “She has obviously the experience. She won those all Grand Slams already. I think she can do it. If she's on her best and great shape, she's playing the best tennis.”
