Serena Williams, the world’s top woman tennis player, now has the most Grand Slam match victories for any man or woman in the Open era. Williams collected Grand Slam win No. 308 after defeating Kazakhstan’s Yaroslava Shvedova in the fourth round of the U.S. Open. The seeded No. 1 player crushed Shvedova 6-2, 6-3 in a little over an hour.  she’s one step closer to claiming her seventh U.S. Open title and her 23rd Grand Slam singles title.

• The historic milestone moves Williams past Switzerland’s Roger Federer, who previously held the title with 307 major match victories.

• If she wins the New York tournament, the tennis star will surpass Chris Evert for the most U.S. Open titles and Steffi Graf for the most championships since the introduction of the Open era in 1968, when the Grand Slam tournaments agreed to permit professional players to compete with amateurs.

• Williams’ very first win at a Grand Slam tournament came way back when she was 16, a 6-7 (5-7), 6-3, 6-1 victory over Irina Spirlea in the first round of the Australian Open on Jan. 19, 1998. Williams’ first loss at a major came in her next match, which happened to come against older sister Venus.
