Don't let the horse's name fool you – Murray Bridge trainer Matthew Seyers does not have a runner in tomorrow's Melbourne Cup.
But his three-year-old colt may forever be the answer to a trivia question in racing circles: which little-known horse briefly threatened to make a cup favourite change its name?
Yucatan has only one race on his record, a 1250-metre handicap at Morphettville in June.
He placed seventh, winning $600.
Yucatan is also a five-year-old Irish stallion with 13 races, two wins – including the recent Herbert Power Stakes at Caulfield – and more than $500,000 in winnings to his name.
He was an easy Melbourne Cup favourite at the time of publication, at odds of $5.50 with TAB on Monday afternoon.
His owner, Lloyd Williams, already has the 2016 and 2017 cups in his trophy cabinet courtesy of Almandin and Rekindling.
Under Australian racehorse naming conventions, an international visitor would ordinarily be required to change its name if a local had already registered it, to avoid any confusion.
International runners have often added prefixes or suffixes to their names, hence the initial suggestion the Irish horse would run as Yucatan Ire on Melbourne Cup Day.
But Racing Australia chief executive officer Barry O'Farrell declared last Tuesday that the usual practice would be reviewed, and ignored in this instance.
"In the current situation ... punters are unlikely to be confused," he said.
A third Yucatan, a gelding, raced in Australia during the 1990s, winning six of its 49 starts and total prize money of $97,000 over a seven-year career.
