Venus Williams' first match since her stellar run to the Australian Open finals didn't go very well.
The fourth-seeded American was no match for Kristina Mladenovic, who rolled to a 6-3, 6-1 victory in a 55-minute second-round match at the St. Petersburg Ladies Trophy event in Russia.
Williams, who received a first-round bye, appeared tired and didn't have the energy to match the effort of Mladenovic. The Frenchwoman won the first five games of the match and cruised throughout.
"Venus is a top player, a top champion," Mladenovic said afterward. "It must have been difficult for Venus to come here after playing back-to-back weekends. I was just trying to play aggressive tennis.
"To be on the same court is a big honor. I'm very happy to say I played with her and that I won today."
Williams lost to her sister Serena in last weekend's Australian Open final. She admitted after Thursday's match that she wasn't in good physical shape.
"Today I wasn't in my best of health," Williams said. "I felt pain in my legs. I had similar feelings during my last match in Australia. I also felt some lack of energy. Definitely it wasn't the best match in my life.
"Also, (Mladenovic) played really well. She played almost a perfect match and gave me no chance today."
Second-seeded Dominika Cibulkova of Slovakia also advanced with a 6-2, 6-2 victory over Donna Vekic of Croatia. Cibulkova will face fifth-seeded Russian Elena Vesnina, who recorded a 2-6, 6-3, 6-3 victory over Alize Cornet of France.
Vesnina defeated Cibulkova at Wimbledon last summer during her surprise run to the semifinals.
"Dominika had an incredible last season -- she's a big player with amazing wins over the last few months," Vesnina said after her match. "She plays very aggressive, puts a lot of pressure and moves incredibly.
"I remember our match in Wimbledon but that was last year on grass, and now we're in St. Petersburg."
