Let's Go Stable's Divine Oath, who did not draw in to Saturday's Grade 1 Blue Grass from the also-eligible list, worked a half-mile Sunday in :48 3/5 in preparation for next Saturday's Grade 3 Lexington.

Working before 7 a.m. (EDT) on his own, the Todd Pletcher trainee posted fractions of :13 1/5 and :25 and galloped out five furlongs on Keeneland's Polytrack in 1:01.

A trio of Grade 3 winners is considered as probable entrants for Saturday's 33rd running of the Lexington at 1 1/16 miles on the Polytrack, according to Keeneland Stakes Coordinator Scott Jones.

The Lexington, which offers 17 points (on a 10-4-2-1 scale) toward the Kentucky Derby, is also expected to attract Ivan Dalos' Ami's Holiday, winner of last fall's Grey at Woodbine; Phipps Stable's Mr Speaker, winner of the Dania Beach on turf; and Susan Moulton's Solitary Ranger, winner of the Arlington-Washington Futurity last September.

Other probable starters include Dynamic Impact and Ride Away. Entries for the race will be taken Wednesday.
