Breeders’ Cup Classic winner Sierra Leone worked Monday for the first time since that signature victory. The son of Gun Runner worked three furlongs in 37.8 seconds.

Trainer Chad Brown is hoping to make the Grade 1 Saudi Cup with Sierra Leone with weekly works to prepare for the race, according to a report from Sean Collins of BloodHorse. The 1 1/8-mile race is at King Abdulaziz Racecourse on Feb. 22. Sierra Leone is a Grade 1 winner at 1 1/8 miles, in the Blue Grass (G1) at Keeneland, though Keeneland’s trip is a two-turn configuration and it is only a one-turn trip at King Abdulaziz.
