"The Toyota Blue Grass nominees represent the most talented three-year-old colts currently on the Derby trail," Keeneland Vice President of Racing W.B. Rogers Beasley said. "We appreciate the strong support of our horsemen, and look forward to an exciting spring meet."

Todd Pletcher leads all trainers with 20 Blue Grass nominees, highlighted by Shanghai Bobby and Verrazano. Bob Baffert is represented by 15 nominees, among them Flashback, Power Broker, Super Ninety Nine and Grade 2 San Vicente Stakes winner Shakin It Up, while Kiaran McLaughlin nominated 12.

Sheikh Mohammed bin Rashid al Maktoum's Darley Stable led owners with eight nominations, followed by Gary and Mary West with seven and Ken and Sarah Ramsey with six.

The Blue Grass was first held at the old Kentucky Association track in Lexington from 1911-14 and from 1919-26, and revived by Keeneland during the track's inaugural spring meeting, held in April 1937. In all, 23 horses -- four at the Kentucky Association track and 19 at Keeneland -- have used the Blue Grass as a path to victory in the Kentucky Derby, most recently champion Street Sense in 2007.

Donegal Racing's Dullahan exploded in deep stretch to run down favored Hansen and win the 2012 Blue Grass. In doing so, Dullahan became only the second horse to win Keeneland's Grade 1 Breeders' Futurity as a two-year-old and return the following spring to win the Blue Grass, joining Horse of the Year Round Table (1956-57).  

NBC will provide live coverage of the Blue Grass from 4:30-6 p.m. (EDT) on April 13. Lexington's NBC affiliate, WLEX TV, will broadcast live from Keeneland from 3:30-4:30 p.m.
