LONDON, March 31, 2026 (ITIA Media Release)
The International Tennis Integrity Agency (ITIA) today confirms that three individuals have been sanctioned under the Tennis Anti-Corruption Program (TACP).
Suspensions have been issued to tennis players Mila Masic, from Serbia, and Jana Vanik, from Germany, and national-level tennis official and administrator Assylbek Kassym, from Kazakhstan.
28-year-old Masic has been suspended for four years and 10 months, and fined $20,000 (of which $5,000 is suspended), after admitting to multiple breaches of the TACP in 2024.
Masic, who reached a career-high world singles ranking of 875 in December 2024, admitted to fixing four of their own matches, receiving payment for these fixes, conspiring to commit corrupt offences, and failure to report corrupt approaches.
Masic accepted an agreed sanction with the ITIA and waived their right to a hearing before an independent Anti-Corruption Hearing Officer (AHO). Time served under provisional suspension will be credited against the player’s period of ineligibility. Having been provisionally suspended since 24 December 2025, Masic’s suspension will end on 23 October 2030, subject to repayment of outstanding fines.
In addition, 23-year-old Vanik has been suspended for one year and four months and fined $1,500 after failing to co-operate with an ITIA investigation.
Vanik, who reached a career-high world singles ranking of 1257 in April 2024, refused to co-operate with the ITIA after a parallel investigation uncovered potential breaches of the TACP. Vanik was also charged with failing to report knowledge or suspicion of active corruption.
Vanik was charged on 27 February 2026, and, after not responding to the ITIA charges, was sanctioned starting 21 March 2026. The period of ineligibility will end on 20 July 2027, subject to repayment of outstanding fines.
Kassym, who has held accredited status as a national-level tennis official, as well as roles in administration and tournament support in Kazakhstan, has been suspended for one year and fined $10,000, of which $7,000 is suspended, after failing to co-operate with an ITIA investigation.
The ITIA uncovered evidence that Kassym had made corrupt approaches to players in 2025, resulting in an investigation. Although initially responsive to ITIA inquiries, Kassym withdrew from communications with ITIA investigators, before ceasing to engage with the process entirely.
After failing to respond to the notice of charge, despite multiple contact attempts by the ITIA, Kassym’s sanction entered into effect on 19 March 2026, and will end on 18 March 2027, subject to repayment of outstanding fines.
During their periods of ineligibility, Masic, Vanik and Kassym are prohibited from playing in, coaching at, officiating at, or attending any tennis event authorised or sanctioned by the members of the ITIA (ATP, ITF, WTA, Tennis Australia, Fédération Française de Tennis, Wimbledon and USTA) or any national association.
