NEW YORK, May 25: Doug O’Neill, the trainer of Triple Crown hopeful I’ll Have Another, was given a delayed suspension on Thursday after one of his horses returned an irregular doping test from a race almost two years ago.

The suspension will have no impact on his star colt’s attempt to win the Belmont Stakes in New York on June 9 because the ban does not kick in until at least three weeks after the big race.

The California Horse Racing Board (CHRB) slapped O’Neill with a 45 day suspension after another of his horses, Argenta, tested positive for excessive levels of carbon dioxide after finishing eighth in a race in August 2010.

The Board had originally charged him with a much more serious offence of “milkshaking”, or giving his horse a mixture of bicarbonate of soda, sugar and electrolytes to run faster.

O’Neill always denied any wrongdoing and after an investigation, the board agreed there was no evidence against him to support the charge.

“The Hearing Officer, who conducted a seven-day hearing, agreed with O’Neill that the evidence demonstrated that Argenta had not been milkshaked, so milkshaking was not the cause of the TCO2 overage,” the Board said in its ruling.

“He also determined there were no suspicious betting patterns in the race. He further determined there was no evidence of any intentional acts on the part of O’Neill in connection with this incident.”—Reuters
