Guillermo Olaso

Guillermo Olaso de la Rica (; born 25 March 1988) is a Spanish professional tennis player who served a 5-year ban from the sport following a 2013 conviction for match-fixing offenses. The suspension, issued by the Tennis Integrity Unit (TIU), was based on violations committed in 2010. Prior to his ban, Olaso reached career-high rankings of world No. 167 in singles and No. 160 in doubles, primarily competing on the ATP Challenger and ITF circuits.

Match-fixing investigation and suspension In December 2013, the Tennis Integrity Unit (TIU) found Olaso guilty of 3 charges under the Uniform Tennis Anti-Corruption Program (UTACP). The investigation determined that in 2010, Olaso failed to report corrupt approaches and engaged in professional misconduct related to match-fixing, including directly or indirectly seeking to "contrive the outcome and any other aspect of any event" .

The TIU issued a 5-year ban and a $25,000 fine . While the final 18 months of the suspension were conditional upon Olaso participating in anti-corruption education, the initial sanction barred him from all professional competition. Olaso appealed the ruling to the Court of Arbitration for Sport (CAS), but the court upheld his suspension in 2014, citing sufficient evidence for the original findings and noting that "the sanction was proportionate and appropriate in the circumstances" .
