All the correct calculations the 13th-seeded Keys has made in the last five matches have led her to Thursday's Roland Garros semifinals against Sloane Stephens. "All in all, I don't think anyone can complain".
"I'm obviously very happy to win in straight sets again and I look forward to the next match". He canceled the third one with a fine drop shot close to the net.
Stephens reached her first Grand Slam semifinal in 2013; Keys did it two years later.
A runner-up at the US Open last season, Keys is into the quarter-finals at a third consecutive major and a fifth time overall, and admits she's finally starting to enjoy the clay.
When asked how she felt about facing friend Keys in the semis, Stephens called it "great for American tennis".
Across the way at Court Suzanne Lenglen, No. 5 del Potro got distracted by a spectator right before a key double-fault, then marched over toward the stands to try to figure out who it was. Keys broke in the seventh game of the second set to maintain her ideal record in Paris, not dropping a set thus far.
Halep, who assured herself of retaining the No. 1 ranking with the victory, earned a fourth chance to win her first major title.
"I like it a little bit more now", Keys says with a smile.More news: Why Prince Louis Was Missing from Today's Trooping the Colour Event
So I think it's become more consistently better for me and something that I'm always going to have to work on, but it's definitely something that's helped me become more consistent.
It's just the most recent example of the South Florida residents' careers paralleling each other. I think there's a difference between being intense and wanting it and fighting and just not being nice, so that's something that I have always stayed true to.
"I think life came at me fast after the US Open and just kind of regrouping and getting myself together, which I did well, and I started playing better and better", she explained.
Stephens consoled a tearful Keys at the end of the US Open final previous year but said there will be no "weirdness" in the locker room this time.
While the Romanian sometimes has trouble with so much on the line, Stephens has been ideal in title matches on the WTA tour, going 6-0.
Mouratoglou adds that there was a concern that if Williams tried to play Monday, she would risk making the injury worse and not be able to play at Wimbledon, which begins July 2. Just one good shot from her here and one bad shot from me there, and then the set was over.
Halep, who lost in last year's final, broke the 16th-seeded Belgian's serve six times on Court Philippe Chatrier. The 23-year-old struggled nine months ago under the pressure with the US Open title on the line, but she is confident that performance won't affect the match at Roland Garros.
"But, in the end, it turns out pretty good for me".
