Muguruza isn't giving he opponent many chances to breathe, and that's the reason for her quick success in these recent matches.
The 24-year-old Garcia's face was in the front page of L'Equipe on Monday, quoting her as saying her goal was to "win a Grand Slam", and she did not change her statement after her 6-2 6-3 defeat on Court Suzanne Lenglen.
The 28th seed clenched her fist after a hold to love got her on the board, but the aggressive Muguruza was celebrating after one of many vicious groundstrokes put her a set up.
Serve and return worked much more efficiently while Kerber struggled to maintain the usual range from the baseline Nonetheless, Halep's overall level of play had been in the ascendancy for most of that set's second half - and, continuing to take control from the baseline, she immediately took her first lead of the match with a break in the second set. In Open Era, No.1 seed has claimed the Roland Garros title on 18 occasions and finished runner-up 13 times. The 24-year-old Muguruza holds a 3-1 record over Halep, with the victor of the last-four clash to face either Sloane Stephens or her fellow American Madison Keys in the final. She broke again in the eighth game to seal the match.
Williams withdrew shortly before the match with a pectoral muscle injury, a moment Sharapova said she found briefly startling but not destabilizing.
"I hadn't had a withdrawal in - I don't know how long. maybe like six years or something", Sharapova said. The German raced into a 3-0 lead with an early double break.
When the top-seeded Halep and No 3 Muguruza meet Thursday, their contrasting styles will match up with plenty at stake. She went on to commit only 16 errors over the course of the next two, which was the difference in getting the win. "If I do that, I will be OK after the match, no matter the result".
It ranked among one of the most lopsided losses ever suffered by Sharapova in her Grand Slam career.
