Spanish fourth seed Garbine Muguruza came back from a set down to defeat Slovakia's Anna Karolina Schmiedlova 3-6, 6-3, 6-3 to reach the French Open second round on Monday.
Muguruza, who has made the quarter-finals for the last two years, will take on French wildcard Myrtille Georges, the world number 203, for a place in the last 32.
But the 22-year-old Wimbledon runner-up was far from impressive in the two and a half hour encounter.
After dropping the first set, Muguruza had to save nine break points just in the opening game of the second set.
She then allowed her 37th-ranked opponent, who has won just one match all year, to claw her way back from 0-4 down to 3-4 before the Spaniard settled herself to see out the win.
Muguruza fired 44 winners and 53 unforced errors and also saved 17 of 21 break points. – AFP
