Serena finalizing her bid for an Open-era record 23rd Grand Slam.
She tied Steffi Graf’s mark of 22 Grand Slam singles titles in the Open era by winning Wimbledon last year.
Since losing the 2008 Wimbledon final to Venus, Serena has won 14 more majors.

She didn’t make the second week for a few years as she came to terms with an energy-sapping illness since being diagnosed with Sjogren’s syndrome in 2011, and made her comeback to the semifinals at Wimbledon last year.
Serena set that mark at 34 years, 287 days when she won Wimbledon last year.
Navratilova remains the oldest Grand Slam finalist in the modern era, reaching the 1994 Wimbledon final at 37, 258 days – more than a year older than Venus is now.
