It was only two months ago that Serena Williams won her 22nd Grand Slam title, tying with Steffi Graf for the second most Grand Slam titles in tennis history. If she should win the U.S. Open this month, she'll finally eclipse Graf, but in the meantime Williams has broken another record.
Today, she beat Sweden's Johanna Larsson and clinched her 307th Grand Slam win in her professional career. That win put Williams ahead of Martina Navratilova and officially made her the winningest woman in Grand Slam history. Just one more win and she'll be the winningest tennis player regardless of gender.
