PRAGUE (Reuters) - Petra Kvitova heads into the French Open with two titles under her belt this year but a calf injury in a tournament tune-up match this week has hit the twice Wimbledon champion's momentum.

The 29-year-old Kvitova was forced to retire from the last major warm-up before Roland Garros with a left calf injury after trailing Greece's Maria Sakkari 7-5 5-7 4-0 on Thursday in the third round of the Italian Open in Rome.
