ROME: French Open champion Garbine Muguruza was forced to retire due to injury from her Rome Masters semi-final against Ukraine's Elina Svitolina on Saturday.
The Spanish third seed was 1-4 down after just 22 minutes in the first set when she quit, handing the eighth-seeded Svitolina a place in Sunday's final against Romania's Simona Halep.
Muguruza had needed three sets to beat Venus Williams in the quarter-finals on Friday night.
Sixth seeded Halep, the champion in Madrid last weekend, reached her first final in Rome after sweeping Dutchwoman Kiki Bertens 7-5, 6-1 in her semi-final.
