Updates on Kentucky Derby contenders and other news as the Run for the Roses is now just 15 days away.

Dynamic duos: Hall of Famers Bob Baffert and Nick Zito, who have won five Derbies between them, hope to each start a pair of runners in this year's edition of the Run for the Roses. Baffert's 2-year-old champion Lookin at Lucky arrived from California on Tuesday and got his first serious work at Churchill Downs on Thursday, covering five furlongs in 1:01.20. Stablemate and Rebel Stakes winner Conveyance covered the same distance in 1:00.20. Zito's Fountain of Youth and Wood runner-up Jackson Bend, currently 21st on the graded earnings list, worked a half in :47.40 on Thursday. Friday morning, it was Florida Derby winner Ice Box's turn, as he went in :48.40. Both colts worked in company.

Arrivals: The consistent Noble's Promise, who is still on the fence thanks to a lung infection, arrived from Arkansas on Thursday. He's expected to breeze on April 20 or 21, following which, trainer Ken McPeek says, he'll be carefully evaluated. Blue Grass runner-up Paddy O'Prado arrived by van from Keeneland on April 13. Santa Anita Derby winner Sydney's Candy also arrived from California that same day, coming in on the same plane as Lookin at Lucky. The son of Candy Ride is expected to work on Saturday morning at Churchill Downs.

Final prep: The Lexington Stakes at Keeneland on Saturday provides trainer Todd Pletcher the chance to get a record sixth entrant into the Derby, as he sends out Connemara, the only horse in the field with a legitimate chance to make the Derby. The half-brother to 2004 Derby runner-up Lion Heart is currently 29th on the graded earnings list with $138,500 in graded earnings, meaning the Lexington's $180,000 purse would boost him into the top 20 that earn a place in the starting gate. Connemara's chief competition could come from the likable colt Uptowncharlybrown, who brings the human interest story into the race - his trainer, Alan Seewald, unexpectedly died earlier this week.

Earnings scramble: Florida Derby runner-up Pleasant Prince (26th on the earnings list) and Bay Shore winner Eightyfiveinafifty (32nd) will run in the Derby Trial at Churchill Downs a week before the Run for the Roses to attempt to earn their way into the Derby field. Even without Triple Crown implications, the Trial is shaping up as a solid race, as Pletcher's stakes-placed Aikenite - already ruled out of the Derby field - figures to start. Meanwhile, Robert B. Lewis winner Caracortado will likely run in the Snow Chief Stakes for California-bred 3-year-olds the same day to try to boost his chances of making the field. If he can't make the Derby or simply elects to pass, he poses a threat for the Preakness.

Oaks watch: Fair Grounds Oaks winner Quiet Temper blitzed five furlongs in :58.60 Friday morning at Churchill Downs. The stakes winning Jody Slew, most recently unplaced in the Fair Grounds Oaks, covered four furlongs in :50 flat.

Notes: Churchill Downs has announced a daily optional reserved training session for Derby and Oaks contenders. For 15 minutes following the renovation break at approximately 8:30 a.m., the track will be closed to all but those horses and their workmates, and horses must wear their track-issues Derby and Oaks saddlecloths to be allowed out. ... Lane's End winner Dean's Kitten is expected to work at Trackside on Saturday morning. ... Trainer Richard Mandella says he'll ship Santa Anita Derby runner-up Setsuko, currently 24th on the earnings list, to Churchill Downs and train him as though he'll make the field.
