Blue Grass entrants train ahead of Saturday's Ky. Derby prep

Untreated, the 8-1 co-third choice for Saturday’s Grade 2, $800,000 Blue Grass (G2), got his first feel of the main track at Keeneland on a brisk Wednesday morning.

“Everything went fine this morning,” said trainer Todd Pletcher’s assistant Amelia Green, who was aboard Untreated as well as Shadwell Stable’s Malathaat, the morning-line favorite for Saturday’s $400,000 Ashland (G1). “They both got here at 5:30 yesterday afternoon (from Palm Beach Downs in Florida).”

Pletcher has won the Blue Grass three times and is the only trainer to have entrants in Saturday’s Blue Grass and Ashland. Six trainers have swept the two races in the same year, most recently Kenny McPeek in 2002 with Harlan’s Holiday and Take Charge Lady.

Entrants for the Blue Grass trained on five fronts Wednesday morning.

Also at Keeneland on the main track were Rombauer, who galloped at 6 a.m. over the wet track under Brian O’Leary, and Essential Quality, the 3-5 morning-line favorite, who galloped at 8:15 a.m. under Elver Vargas.

Hidden Stash galloped 1 1/2 miles on Keeneland’s all-weather training track, where he was joined by Hush of a Storm.

Highly Motivated and Keepmeinmind trained at Belmont Park and Oaklawn Park, respectively. Both horses are scheduled to arrive at Keeneland later Wednesday.

Leblon jogged at The Thoroughbred Center in Lexington on his first day back on the track following a half-mile work in :49 on Monday.

Sittin On Go trained at Churchill Downs.
