Having missed the main draw cut-off date as she waited for a nagging wrist injury to heal, Jovanovski was forced to come through qualifying, and in the first set against Voskoboeva it looked like these extra matches were beginning to take their toll.
On a wind-swept Centre Court, Voskoboeva set the tone with a break to love in the opening game and required little over 20 minutes to rattle through the rest of a one-sided set. Jovanovski gained a belated foothold with an early break in the second, and despite surrendering this advantage soon after managed to force a decider with some characteristically fierce hitting from the baseline.
Both players had their opportunities in the decider, but when it headed into a tie-break it was Jovanovski's consistency that won out, edging her over the finishing line, 16 64 76(5).
"I didn't start well in the first set - it was so windy! In the middle of the second set I got my rhythm and started being more aggressive," Jovanovski said. "Galina played wonderful tennis, mixing up her game using serve and volleys and drop shots effectively, at the end I managed to win and I'm very happy about it."
Torró-Flor has enjoyed the best results of her career to date on clay, but her heavy groundstrokes have looked very much at home on the hardcourts of the Olympic Tennis Complex. "I was expecting a tough match and prepared well," Torró-Flor said. "I'm happy to be in my first ever WTA semifinal. I started well, played confidently and focused on my match.
"I'm playing better on hard and concentrating on playing aggressive tennis - I'm not thinking of points but I'm thinking of improving my game."
Burnett made a bright start, but was punished for her failure to convert any of the three set points she carved out a 5-3 in the opening set, eventually slipping to a 76(4) 75 defeat. Meeting Minella for a place in the final will be Olga Govortsova after she eased out No.5 seed Alexandra Cadantu, 63 62.
