No regrets for Graf when Serena breaks record

Steffi Graf believes her Open-era record of 22 major singles titles will soon be eclipsed by Serena Williams - and she insists she will be happy for the American when it happens.

Williams, who has won 21 Grand Slam singles events, was thwarted in her bid to tie the long-standing mark at the Australian Open in January when she was upset in the final by Angelique Kerber.

But Graf expects Williams to come roaring back.
