GARBINE Muguruza conquered nerves and the greatest player in contemporary tennis to stall Serena Williams pursuit of grand slam history with an inspired French Open triumph.
Muguruza, 22, is the first Spanish woman to win the Roland Garros title since Arantxa Sanchez Vicario in 1998, prevailing with a deserved 7-5 6-4 success.
Appearing in her 27th grand slam final, Williams tasted defeat for only the sixth time.
The champion here in 2002, 2013 and last year, Williams simply could not come to terms with Muguruza’s heavy drives from both wings.
The Spaniard hit 18 winners and made only 25 unforced errors but she forced Williams into a 39 mishits.
Muguruza earned $3million for the win and will rise to No 2 behind Williams in the rankings tomorrow.
My dream is to continue and win more tournaments, similar tournaments, and to dominate," the Venezuela-born Muguruza told reporters after her 7-5, 6-4 victory on Court Philippe Chatrier.
"When I am on the court I want to dictate my game and bring more of these cups back home," added the Spaniard, who became the second player after Australian Open champion Angelique Kerber to beat Williams in a majors final this year.
"She's number two after this, only one more step to be number one and I am sure she's going to win many more grand slams," said former Spanish player Conchita Martinez, the 1994 Wimbledon champion and 2000 Roland Garros runner-up.
"She's a great player on any surface, she is a complete player. Spain is very lucky to have this unbelievable tennis player."
Williams, who was aiming to equal Steffi Graf's professional-era record of 22 majors, was the favourite to win her third Paris title in four years but she fell one win short of the target - just as she had done at the Australian Open in January.
Her coach, however, warned that the 34-year-old Williams would stay on Muguruza's radar for quite some time.
"It shows how hard it is to win a grand slam, to equal records. It will take the time it will take, it was tough to win the 17th, the 18th, it will be hard to win the 22nd and the 23rd but we will do it," Patrick Mouratoglou said.
