In the last tournament before the US Open starts on Monday, the first semi final in the New Haven at Yale tournament was between two Czechs – 3rd seed Petra Kvitova up against the unseeded and 33rd ranked Klara Zakopalova. Zakopalova took out 8th seed Dominika Cibulkova in the first round in three sets, a qualifier in straights in the second round and Elina Vesnina in the quarters. Kvitova battled past a lucky loser in three sets in the first round, battled even harder in a three setter against a qualifier in the second round and had another tough three setter against Pavlyuchenkova in the quarters. All those tough matches seemed to pay off, as the defending champion of this tournament came on court and simply swept her countrywoman off the court in just fifty minutes, allowing her just one game in the second set.
The second semi was played at night with 5th seed Caroline Wozniacki pitted against 23rd ranked Simona Halep. Halep lost just three games in her opener, fought a tough three setter in the second round and then took out Elena Makarova in the quarters in straights. Wozniacki was lucky to get through her first round match when Shuai Peng had to retire when leading 6-2 1-3. She then won in straights in the second round and took out 6th seed Sloane Stephens in the quarters, also in straights. Halep eased through the first set 6-2 in just over half an hour. There were breaks of serve at the start of the second set with the Dane fighting all the way and she managed to get ahead twice to lead 4-3 and 5-4, but Halep raised her game each time, got the vital break for 6-5 and served out the set to book her place win the final.
