The American cruises into the semifinals

Muguruza opened up the first game of the second set but Vandeweghe was virtually unplayable, getting a 0-40 lead on the Spaniard's serve. On the second break point chance, Muguruza served big out wide but Vandeweghe already moved to her right and produced an outrageous forehand return winner down the line.

Vandeweghe won her third consecutive game of the match and consolidated the break to lead 2-0. Once again, Muguruza's serve was under severe scrutiny as Vandeweghe was producing winner after winner, a double break handed the American a 15-40 lead and she came out on top in a 12-shot baseline rally with a forehand winner down the line to get the insurance break and lead 3-0.

Muguruza didn't have the answers in the following game, and Vandeweghe had the finishing line in sight by winning her fifth consecutive game of the match leading 4-0. It was important for the French Open champion to hold serve in the fifth game but immediately a short ball was punished by the American with a backhand winner down the line. Furthermore, Muguruza would get a 30-15 lead by virtue of two errors from the Spaniard, moreover, Vandeweghe would continue her dominance with an eight shot rally and punishing winner in the corner. An untimely double fault handed Vandeweghe a chance to break with a forehand winner to break Muguruza for the third time in the match and lead 5-0.

The American's service game was the most important service game of her career. She led 30-0 but Muguruza responded with a backhand winner down the line in an eight-shot rally, and the world number 35 would create more unforced errors to give Muguruza a lifeline break point. The 25-year-old managed to save it coming out on top in a seven-shot rally with a forehand crosscourt winner. Once again Muguruza struggled in the extended rallies, and Vandeweghe would cause the upset by defeating the French Open champion, 6-4, 6-0 in 1 hour and 24 minutes.
