MOSCOW, REUTERS — The top players could boycott next year's WTA Tour if their questions were left unanswered, world No. 3 Dinara Safina said Saturday.

The Russian said the players were unhappy with the changes being made to the schedule.

"If they (WTA) don't listen to what we have to say we might even choose to boycott the new tour," Safina told reporters after losing 6-2, 7-6 to compatriot Vera Zvonareva in the Kremlin Cup semifinals.

"They said the leading players would have to play in designated tournaments while lower-ranked players would be able to enter any event they like. There's no logic in that at all.

"What if all the top players choose to enter the same tournament? What will the WTA do then? We want to know," added Safina.
