Trainer Bill Spawr has been suspended 30 days and fined $3,000 as part of a settlement agreement with the California Horse Racing Board after Skye Diamonds showed an excessive amount of clenbuterol in a post-race test taken after her second-place finish in the Grade 3 Adoration Stakes at Santa Anita on May 7.
The suspension begins Monday and continues through Sept. 26.
Spawr was suspended 60 days but 30 days of the penalty will be stayed provided Spawr adheres to the term of a probation period for one year.
Spawr is denied access to the racetrack during the suspension.
Skye Diamonds has emerged as the leading female sprinter in California, with consecutive stakes wins in recent months - the Grade 2 Great Lady M. Stakes at Los Alamitos in July and the Grade 3 Rancho Bernardo Handicap at Del Mar earlier this month.
