SYDNEY - China's Wang Xinyu was knocked out of the WTA Hobart International tournament on Thursday when she lost 6-3, 6-3 to world No 84 Lauren Davis of the United States in the quarterfinals.

After a five-day warm-up at the Domain Tennis Center, the 21-year-old Chinese will next move to Melbourne Park to take on world No 227 Storm Hunter in the opening round of the Australian Open.

During the 85-minute encounter with Wang, Davis landed 77.6 percent of her first serves and saved four out of five break points on the center court. The American qualifier joined her compatriot and former Australian Open winner Sofia Kenin into the final four of the tournament.

For another US player Bernarda Pera, her quarterfinal showdown with Italy's Elisabetta Cocciaretto was a second physical test after her Wednesday's laborious win over Germany's Laura Siegemund in a three-hour rubber.

The match with Cocciaretto once again took Pera almost three hours - two hours and 47 minutes to be exact, but this time the sixth-seeded Pera bowed out from the tournament with a 5-7, 7-6 (8), 6-4 defeat to her lower-ranked Italian opponent.

A second upset later unfolded between Anna Blinkova of Russia and Yulia Putintseva of Kazakhstan. The world No 72 Russian stormed into the singles semis by stunning the eight-seeded and world No. 51 Putintseva 6-3, 6-4 in a 100-minute game.
