New York: Steffi Graf doesn't see anyone stopping Serena Williams from becoming the career leader in Grand Slam singles titles.
Serena earned her 17th major title at the U.S. Open this month. Graf, who won 22 titles, believes Williams will surpass leader Margaret Court at 24.
"She's got a lot of tennis left in her," Graf said. "I can easily see her pass all of our records. I don't see the competition catching up to her."
