Caroline Wozniacki

Caroline Wozniacki's hopes of returning to the World No. 1 spot were dashed yesterday by a surprise defeat to Dutchwoman Kiki Bertens at the Madrid Open. Wozniacki would have taken top spot from Simona Halep had she won the title this week, but the Dane saw Bertens progress to the quarter-finals instead thanks to a 6-2, 6-2 victory. After winning her first Grand Slam at the Australian Open in January, Wozniacki moved back to the summit of the rankings for the first time since 2012.
