PARIS, May 28 (Reuters) - Czech fourth seed Petra Kvitova laboured into the third round of the French Open as she overcame Spain's Silvia Soler-Espinosa 6-7(4) 6-4 6-2 on Thursday.
The double Wimbledon champion, a semi-finalist on the Paris clay in 2012, made 54 unforced errors in a patchy display on a chilly court Suzanne Lenglen.
After two exchanges of breaks, the first set went into a tiebreak that the Spaniard easily won but Kvitova eventually found her range.
She ended the contest on her first match point to set up a meeting with Romanian 30th seed Irina-Camelia Begu or American Bethanie Mattek-Sands. (Reporting by Julien Pretot; Editing by Justin Palmer)
