She endured an eight-match losing streak after leaving NY, going 0-6 for the rest of 2017 and then 0-2 to begin 2018, including a first-round loss at the Australian Open.
French Open 2018 nearly presented the momentous occasion where the bitter rivals - Serena Williams and Maria Sharapova - former World Number ones, were about to clash in the 4th round. Muguruza, who is 3-1 against the No. 1-seeded Halep in her career, has never squared off with her in a Grand Slam.
Not only is a French Open final on the line this afternoon, but the victor today will also claim the world No. 1 ranking.
The 2012 and 2014 Paris champion, who missed the 2016 tournament because of a doping ban and past year when she was refused a wild card, was broken six times, committed 27 unforced errors and won just five points on her own serve in the second set. In the victory, Halep won 61 percent of her first serve points and 53 percent of her second serve points.
Yesterday's matches in Paris saw Simona Halep fight back from the disappointment of losing the first set on a tiebreak against Angelique Kerber to take the next two sets in relatively facile fashion, while our selection, Maria Sharapova, disappointed in the extreme in her defeat to Garbine Muguruza, who created 12 break points and faced just one. She was prior to the draw and it took a gift draw for Elina Svitolina - which the Ukrainian was unable to exploit - for her to lose this status for the opening two rounds.
Muguruza's big strokes overwhelmed Maria Sharapova right from the start and their quarter-final was no contest at all in a 6-2, 6-1 one-way journey.
"If I make it all, it's very well. I just try to keep that going". And I will try just to be calm during the match and try everything I can. And I think we played many matches. She's hitting the ball.
"I played again one of my best matches on clay", Halep said after coming back from a break down in the second set against Muguruza.
Keys will have to be patient in this semi-final, and only pull the trigger when she's ready to finish off the point.
"Life came at me fast after the U.S. Open", said Stephens, whose late father, John, was the 1988 NFL Offensive Rookie of the Year with the New England Patriots.
