MIAMI, Florida: Sergiy Stakhovsky, Ukraine's top ranking men's tennis player and a member of the ATP international professional tour, has been sued in Miami-Dade County Circuit Court for breach of contract, breach of fiduciary duty and unjust enrichment.

            A companion lawsuit for tortuous interference with a contractual relationship also has been filed against Global Sports Management Ltd. and its president, Dirk Hordorff, the player's current manager.

            Each lawsuit seeks damages in excess of $1 million. They were filed by Renaissance Tennis Management (RTM), Stakhovsky's manager. Stakhovsky began living and training with RTM in late 2006, working with RTM's coaches at various South Florida locations.

            "Sergiy Stakhovsky would not be the player he is today without the help and the financial support provided for him by Renaissance Tennis Management," said Adam Kenner, RTM's attorney. "Mr. Stakhovsky simply did not honor his end of a business relationship, and must believe he is not bound by his contractual obligations."

            The lawsuits assert that Stakhovsky failed to pay RTM for its training and management services, and that Hordorff and Global Sports Management interfered with RTM's management of Stakhovsky while the player was still under contract with RTM.

            Stakhovsky, a Ukrainian citizen, currently is ranked No. 70 in the world and is playing at the Sony Ericsson Open tournament beginning this week in Miami. He currently resides in Bratislava, Slovakia.
