Maria Sharapova claimed her second French Open title when she floored Romanian fourth seed Simona Halep 6-4 6-7(5) 6-4 after a marathon encounter in Saturday's final.
The seventh seed from Russia claimed her fifth grand slam title after Wimbledon 2004, the 2006 US Open, the 2008 Australian Open and her first Roland Garros title two years ago.
Halep, who had not lost a set entering the final, put up a great fight but bowed out after three hours and two minutes - the longest women's final in Paris since 1996.
Sharapova wrapped it up on her first match point when Halep could not return one of her opponent's sizzling forehands.
"This is the toughest grand slam final I have ever played. I respect Simona a lot, I thought she played an unbelievable match today," Sharapova said with smudged mascara under her eyes.
"I can't believe it, seven or eight years ago I would not have thought that I would win more Roland Garros than any other grand slam.
The wily Romanian had forced a decider just as Sharapova seemed to have ended her resistance.
The Russian, however, had won the last 19 three-set matches she had played on clay since losing to Justine Henin in the third round at Roland Garros in 2010 and made it 20 with a characteristically gutsy display.
Halep, hoping to become the second Romanian woman to win a grand slam title after her manager Virginia Ruzici won at Roland Garros in 1978, broke in the first game of the match when Sharapova sent a backhand long despite having an open court at her disposal.
Sharapova unsettled Halep with her crosscourt shots but the Romanian held on for 2-0.
The Russian bombarded Halep with powerful forehands and managed to break back for 2-2 on her fourth chance when Halep's crosscourt backhand went wide.
Sharapova's third double fault gave Halep another break point, which the Russian saved with another forehand winner down the line before holding for 3-2 after four deuces.
The Russian broke for 4-2, went to 5-2 and then lost two games before taking the set on her opponent's serve when Halep fired a crosscourt forehand wide.
Sharapova won the first game of the second set to love and broke in the second with the contest seemingly heading for a swift conclusion.
