History was on the line for Serena Williams - three Slams in a row, 20 total, the Aussie-French double...
And Lucie Safarova was hungry for an upset, playing the tennis of her life to make her first major final.
It was their ninth career meeting, and Williams had a big advantage - she was 8-0 against the Czech.
And it looked like that pattern would continue on Court Philippe Chatrier on a sunny Saturday afternoon.
Williams stormed out to a 6-3, 4-1 lead in little over an hour, with points for a 6-3, 5-1 lead.
Safarova, who hadn't dropped a set in six matches en route to the final, looked very down and out...
But there's a reason she took out players like Maria Sharapova and Ana Ivanovic earlier in the fortnight.
The No.13 seed came alive down 6-3, 4-1, 40-15, clawing back and taking the second set in a tie-break.
Williams was on the defense - Safarova not only took that middle set, she raced out to 2-0 in the third.
But the No.1 seed turned it around from there, reeling off six games in a row to sneak out the victory.
Williams edged Safarova out in front of an enthralled Court Philippe Chatrier crowd, 6-3, 6-7(2), 6-2.
She had her third straight Slam, her 20th overall Slam and that coveted Australian-French Open double.
She also improved to 9-0 against Safarova, though four of those nine meetings have been three-setters.
Williams will now have a massive 4,421-point lead over Petra Kvitova at the top of the WTA Rankings.
She will also extend her lead over Maria Sharapova and Simona Halep on the Road To Singapore leaderboard.
