Madrid - Defending champion Simona Halep came from 5-2 down in the final set to beat Roberta Vinci 6-3, 2-6, 7-6 (7/2) to reach the third round of the Madrid Open on Tuesday.
Halep very nearly became the latest seed to fall in a decimated bottom half of the draw after early exits for Karolina Pliskova, Garbine Muguruza and Johanna Konta.
However, the Romanian bounced back from losing nine of 11 games from 2-2 in the second set to force the deciding set into a tie-break.
And with 34-year-old Vinci sensing her chance had gone, Halep raced through the tie-break to set up a last-16 clash with Australian 16th seed Samantha Stosur.
