While Serena Williams was made to labor for her French Open semifinal win against unseeded Kiki Bertens, Garbine Muguruza unfurled all the weapons that could one day take her to the top of women's tennis when 34-year-old Williams finally makes way.
Aside from a late bout of nerves when serving for the match, fourth-seeded Muguruza was imperious in her semifinal on Friday against Samantha Stosur, bossing the Australian with her speed and power from the back of the court and her steadiness at the net.
Muguruza's maturity belies her 22 years. The two-time quarterfinalist at Roland Garros has barely put a foot wrong on way to her first French Open final, dropping just one set - in the first round.
She broke Stosur five times, profiting from the No.24-seeded player's string of errors - including two double faults on break points in the second set.
Muguruza has won just one of her four previous meetings with defending French Open champion Williams, but it should give hope for Saturday's final, because it was on the clay of Roland Garros, in the second round in 2014. Muguruza won 6-2, 6-2.
The last time they played was also for a Grand Slam title, at the Wimbledon final in 2015. Williams won 6-4, 6-4.

Serena Williams moved one victory from her second consecutive French Open trophy and 22nd Grand Slam title overall, beating Kiki Bertens 7-6 (7), 6-4 in the semifinals Friday.
For the second match in a row, the No. 1-seeded Williams was hardly at her best, falling behind early and making 22 unforced errors in the first set alone. Williams needed to erase two set points for the 58th-ranked Bertens in the opener, but managed to get through it.
In the final, Williams will face No. 4 Garbine Muguruza of Spain, a rematch of last year's Wimbledon title match won by the American.
If Williams wins Saturday, she will equal Steffi Graf's Open-era record of 22 major championships. Only Margaret Court, with 24, has won more.

Garbine Muguruza is into her first French Open final.
The fourth-seeded Spaniard beat Samantha Stosur 6-2, 6-4.
Muguruza served two aces to bring up match point and won in 1 hour, 16 minutes when Stosur netted her stroke.
Muguruza was also a finalist at Wimbledon in 2015.
Stosur was undone by a string of errors, including twice serving double faults on break points in the second set.
Muguruza served for the match at 5-2 but was broken to love, the victim of nerves.
''It's always a difficult moment,'' she said.

Serena Williams fended off two set points and converted her second to take the opener 7-6 (7) against Kiki Bertens in their French Open semifinal.
The top-seeded Williams, aiming for a second consecutive title at Roland Garros and her 22nd Grand Slam championship overall, trailed for most of the set and got her only break when Bertens served for it at 5-4.
They played in chilly, cloudy conditions and in front of a mostly empty Court Philippe Chatrier.

Garbine Muguruza has raced to a first-set lead in her French Open semifinal against Samantha Stosur, who made an unsteady start strewn with errors.
Stosur served first, and was immediately under pressure. The fourth-seeded Muguruza hit a forehand smash at the net to earn two break points and converted the first to take a 1-0 lead.
The Spaniard then saved two break points on her serve and broke the 24th-seeded Australian again, when Stosur served a double fault - her second - at 15-40.
The set then stayed with serve to 5-2 for Muguruza.
She then served out the set, with a volleyed forehand winner bringing up set point and Stosur then hitting a backhand service return long, for a 6-2 first set in 34 minutes.

It's far from a full house for the start of the two women's semifinals being played, unusually, at the same time and on a Friday at the French Open, with many seats unfilled.
There are blocks of empty seats on the main Court Philippe Chatrier, where defending champion Serena Williams was broken in her first service game by the unseeded Kiki Bertens.
An effort to fill the adjacent Court Suzanne Lenglen, where Garbine Muguruza has jumped to a 4-0 first-set lead against Samantha Stosur, by offering 8,000 cheap 20-euro ($22) tickets appears to have met with limited success, with large areas of empty seats.

A day late, two women's semifinals are underway at the French Open, played simultaneously on separate courts to squeeze them in after a rain-wrecked week before the final on Saturday.
Had damp weather not thrown off the schedule, Serena Williams, Kiki Bertens, Garbine Muguruza and Samantha Stosur normally would have played their semifinals on Thursday, leaving the finalists a full day of rest before the championship match.
But unrelenting rain that washed out a whole day of play on Monday, for the first time in 16 years, and other wet-weather delays nixed those plans.
Instead of being played one after the other on the main Court Philippe Chatrier, they're now playing at the same time. Defending champion Williams is up against the unseeded Bertens on Chatrier, with fourth-seeded Muguruza and No. 24 Stosur next door on Court Suzanne Lenglen.
