Simona Halep
Yes, she’s for real—Top 5 real. The Romanian broke into that elite company with a semifinal run which included close wins over Lucie Safarova and Genie Bouchard. It’s the ultimate commentator’s cliché, but it’s true in her case: The next step is to get to the net more. With her hands, it could make a difference. B+
John Isner
Isner did what he does: Play well at home, and win tiebreakers. It was enough to send him back into the Top 10. Better, from a U.S. tennis perspective, was what he had said when he got there: “I want to go farther.” That’s not something we’ve heard much from the American men recently. B+
Alexandr Dolgopolov
Like Pennetta on the women’s side, it’s hard to think of a more welcome potential addition to the upper echelon of the men’s game. Dolgo has always had the flash; this year he’s added some substance. But he’s not yet the serious threat he could be, as his smiling surrender to Federer in the semis showed. B+
Jelena Jankovic
JJ continued her late-20s revival with a masterfully easy win over Caroline Wozniacki, then gave Radwanska everything she could handle in the quarters. All of this while spending half her time sprawled on the court. B+
Sloane Stephens
Aggressive play, a better attitude, some good wins, and a quarterfinal loss to the eventual champion: Was this a turning point for the young American, who made her debut with new coach Paul Annacone? There will be more defeats and bad days, but this was her best week of the year so far. B+
Ernests Gulbis
Is it a coincidence that the one match in which Gulbis didn't smash a racquet was the one he lost? Get <em>madder</em>, Ernests. <strong>B+</strong>
Dominic Thiem
With a third-round run and a win over Gilles Simon, Thiem was the new face—and one-handed backhand—of the tournament. Power lovers should love this young Austrian, who has yet to meet a ball he couldn't bash. B+
Marin Cilic
He played the set of his life to beat Djokovic 6-1; for a few minutes, we saw the Cilic many of us thought we would see when he arrived on tour nearly a decade ago. He hit with pace and angle, rather than with margin and safety. Then he went back to normal and lost. B
Jiri Vesely
As he showed in his snatching-defeat-from-the-jaws of victory match with Andy Murray, the young Czech has the hands. Now he needs the head. B
Camila Giorgi
It was fun, before she disappeared again, to see the young Italian take the ball on the rise and give it a ride past Maria Sharapova. B
Li Na
She reached the semis, but this wasn’t the tennis you would expect from a world No. 2 who had just won a Grand Slam. Unforced errors, double faults, blown match points, and breaks of serve were the constants in her week. B-
