The Canadian-born trainer made a huge splash in his first season at Oaklawn in 2015 and was equally successful in ‘16. He was among the top 5 trainers with 22 wins, including four straight with Subtle Indian, who won the $100,000 Hot Springs and $400,000 Count Fleet Sprint Handicap (G3).
Diodoro recorded his first career Oaklawn stakes victory when Subtle Indian won the 2015 $100,000 Gazebo Stakes for 3-year-old sprinters.
He was North America’s fifth-winningest trainer in 2014 with 243 victories and was seventh in 2015 with 190 wins. He has also edged perennial Canterbury champion Mac Robertson for the training title at the Minnesota track the last two years.
He maintains a string of approximately 80 horses and in addition to Oaklawn, also keeps horses at Turf Paradise in Phoenix, where he resides, and Santa Anita in the winter.
Diodoro, who comes from a racing family, began training in 1995. His grandfather trained and Diodoro took over the one-horse operation in his early twenties.
