Ed McGrogan, Senior Editor: Petra Kvitova
Every contender has questions, even Serena Williams. Kvitova was slotted into a generous quarter of the draw, at least, and she showed the form we were expecting from her this year in Madrid. The time is now for her to turn her season around.
Nina Pantic, Associate Editor: Simona Halep
The biggest things stopping Halep from winning her first major in Paris last year were Maria Sharapova and her own belief. Winning Indian Wells this year and pushing Serena to 7-5 in the third in Miami must give the 23-year-old confidence on both fronts. She may need a little luck, but she has the skill to take advantage of any good fortune that comes her way.

She’s more vulnerable than usual, but an early test against Victoria Azarenka may be just the spur she needs to send her into the second week in peak form. Once she’s there, history says she’ll probably win it all.
