Repole Stable's UNCLE MO (Indian Charlie) and STAY THIRSTY (Bernardini) jogged a mile with trainer Todd Pletcher's first set Monday shortly after the track opened for training at 5:45 a.m. (EDT).

"Both seemed very well (this morning)," Pletcher said later at his Barn 34 headquarters. "We took them out for a light jog today. They both ate up last night and appear to be doing well. Knock on wood, we're good."

The duo just got some easy exercise the day following their tandem five-furlong drill. On Sunday, last year's two-year-old champion Uncle Mo covered the distance in 1:01 3/5 and his stablemate and Gotham (G3) winner Stay Thirsty recorded a time of 1:01 4/5.

In a correction from Sunday's notes, Kentucky Derby (G1) rider John Velazquez was aboard for Uncle Mo's work, not exercise rider Hector Ramos as previous reported. Stay Thirsty will be ridden by Ramon Dominguez in Derby 137. 

Exercise rider Carlos Correa took Robert LaPenta's DIALED IN (Mineshaft) to the track at 7.a.m. Monday for a long gallop over the sloppy surface at Churchill Downs.

"He galloped a pretty long way, went around twice there," trainer Nick Zito said during a break in the morning rains. "It was just like this when he went out, but then God said, 'Nah, I want him to get wet like the other horses.' But he liked it.

"I can't remember, believe it or not, since I got him galloping on a track like that. I think that was the first time -- this morning -- that he galloped on a wet track. It looked like he did all right."

The ever-superstitious Zito, who has saddled Strike the Gold (1991) and Go for Gin (1994) for victories in the Kentucky Derby, has been outwardly and comfortably confident in Dialed In this spring, although he did make an effort to knock on wood outside Barn 36 when he talked about his positive feelings about the colt.

"I'm just confident with a horse like this. To me, he's a special horse. He always tries so hard, it's nice to have a horse like that. You know he's going to put in his run," the Hall of Fame trainer said. "I'm always confident when I have a horse like this – confident, but not overconfident."

Dialed In, who won the Holy Bull S. (G3) and the Florida Derby (G1) at Gulfstream Park, has returned to Churchill Downs, a more mature-looking colt than the one who broke his maiden here last November.

"He was a little bit of a butterball. He was a little chunky. Obviously, he streamlined. He's not a very big horse, but he streamlined down beautifully," Zito said. "He's a gorgeous horse. I think his development has been terrific."

Florida Derby runner-up SHACKLEFORD (Forestry) got back to work Monday morning with a two-mile jog at Churchill Downs with trainer Dale Romans watching. Co-owned by Michael Lauffer and Bill Cubbedge, Shackleford has posted two fast workouts in recent weeks, including a bullet five furlongs Saturday in :58 4/5.

"I thought both of his workouts were just perfect," Romans said. "They were fast, sure, but they were in hand. That's what you want to see, a fast horse working without being asked hard." 

Romans trained horses who placed in all three legs of the 2010 Triple Crown, including a third on Kentucky Derby Day with Paddy O'Prado (El Prado [Ire]), a second in the Preakness (G1) with First Dude (Stephen Got Even), and a third in the Belmont (G1), also with First Dude.

"This horse, Shackleford, reminds me a lot of Paddy O'Prado last year, who peaked at the right time," Romans said. "He couldn't be doing any better."

Shackleford will school at the starting gate Tuesday and Thursday, while Romans said he would likely school in the paddock during the races sometime this week as well.

Jesus Castanon will have his first Kentucky Derby mount aboard Shackleford.

Harvey Clark and partners' SOLDAT (War Front) galloped 1 1/4 miles Monday morning under exercise rider Danny Wright. Trainer Kiaran McLaughlin said on a fast track he would gallop a bit longer, but cut things short by plan because of the sloppy track conditions.

Sloppy track or not, McLaughlin said Soldat already has appreciated the change in climate.

"It was 90 degrees on Florida Derby Day and they all got pretty hot that day," he said. "And the last 10 days he was at Palm Meadows, it got pretty hot and muggy down there. But with the wet weather in Kentucky, I'm glad we kept him down in Florida even with the heat.

"He really picked his head up since coming to this cooler weather. Going from hot to cool for a horse is like a vitamin shot."

But McLaughlin won't shed any tears if the track turns up sloppy on Saturday for the Derby.

"We won't mind the slop, look at what he did on that sloppy track at Gulfstream," he said, referring to a 10  3/4-length allowance win in January. "That won't bother me on race day, but I'd prefer to train on a fast track any day."

Alan Garcia rides Soldat in Derby 137.

Robert and Val Yagos' Arkansas Derby (G1) winner ARCHARCHARCH (Arch) galloped 1 1/2 miles after the renovation break over a sloppy track with jockey Jon Court aboard.

The owners were driving to Louisville from Jacksonville, Arkansas, Monday and expected to be on hand during training hours Tuesday morning when more rain is expected.

The long-range forecast for Derby Day calls for a 30 percent chance of rain and Court was asked if he had any concerns about Archarcharch handling a wet track.

"I would prefer a dry track, but they all have to run on it," said Court, who will be riding in his first Kentucky Derby. "It doesn't show (on his past performances), but he has had experience on an off track. I am confident in his ability and skill to think that he could handle it."

Archarcharch's only off-the-board finish in six starts came on a track listed as "good" in a fourth-place finish in the Smarty Jones at Oaklawn Park on January 17.

"That day," Court said, "that track was muddy, sticky and tiring."

Reeves Thoroughbred Racing and Dream Team Racing's MUCHO MACHO MAN (Macho Uno) galloped two miles at Churchill Downs Monday morning after the renovation break under regular exercise rider Mike Herra.

The Kathy Ritvo trainee, who breezed five furlongs in 1:00 2/5 Saturday morning, returned to the track after walking the shedrow on Sunday. Ritvo expressed complete satisfaction in her colt's preparation at Churchill for Saturday's Kentucky Derby.

"He's pretty laid back and he's gotten used to everything. I'm sure there's nothing that compares to Derby Day, but we're going to try until we get there," she said. "I'm honored to be here. I'm excited to be here. Everything's going good with the horse, so it couldn't be any better."

Mucho Macho Man, who captured the Risen Star S. (G2) at Fair Grounds before losing a shoe during a close third-place finish in the Louisiana Derby (G2), hasn't caused his trainer one anxious moment since arriving at Churchill Downs on April 18.

"I'm just blessed and fortunate that he's doing so well here. We haven't had anything to deal with. He loves the mud; he loves the track," the South Florida-based trainer said. "He's been great around here. The weather has been for him. For me, I don't like the rain."

Team Valor International's ANIMAL KINGDOM (Leroidesanimaux [Brz]) returned to the track Monday morning and jogged a mile over a sloppy course.

Dan Rock, assistant to trainer Graham Motion, sent the Spiral (G3) winner out a little after 7 a.m. during a short break in the rain. The colt worked six furlongs Saturday morning in 1:13, and Rock said the colt has come out of the work in good order.

Trainer Juan Arias was aboard DECISIVE MOMENT (With Distinction) for a morning gallop Monday following the renovation break at Churchill Downs, where another man by the name of Juan Arias visited the winner's circle with 1971 Kentucky Derby winner Canonero II.

Decisive Moment's trainer is quick to point out that he is no relation to the trainer of the Venezuelan invader who pulled off the shocking victory 40 years ago.

"People want to make me Juan Arias II, but I don't want to be second. I want to be first," Arias quipped.

Arias, though, admitted that he wouldn't mind if Decisive Moment followed in Canonero II's footsteps and pulled off an upset in the Derby.

The South Florida-based trainer reported that the Just For Fun Stable's homebred colt galloped well over the sloppy track Monday.

"He loved it. I wish on race day it would be the same way," he said. "He's been here a month and tried every condition this track can have, and he adjusts perfectly on all of them. No surprises for him."

Kerwin Clark will ride Decisive Moment in the Derby.

George and Lori Hall's PANTS ON FIRE (Jump Start) did not visit the track one day after breezing a half-mile in :47 4/5. However, trainer Kelly Breen relayed that the Louisiana Derby winner came out of his work in good order.

"He looks good, he's eating good, and when I showed up this morning he was resting well," Breen said. "He's up and around now and doing well."

Pants on Fire will return to galloping during the Derby-Oaks training session Tuesday.

TWICE THE APPEAL (Successful Appeal) and SWAY AWAY (Afleet Alex), the two colts trained by Jeff Bonde, walked the shedrow for a second day following six-furlong works on Saturday.

Twice the Appeal, who earned his way into the 137th Kentucky Derby with a tally in the Sunland Derby (G3) in March, covered the distance in 1:15 3/5, while Sway Away, who is not yet guaranteed a spot in Saturday's starting gate, went the six panels in 1:14.

Bonde's assistant trainer, Miguel Carranza, confirmed that the double walk days were standard procedure in their barn.

"That's the way he (Bonde) likes to do it," Carranza said at Barn 42 Monday morning. "We'll take them back to the track tomorrow."

Sway Away is No. 23 on the list of eligibles for the prestigious race that only allows for 20 runners. Entries for the Run for the Roses will be taken Wednesday.

Calvin Borel has the call on Twice the Appeal, while Martin Garcia would be aboard Sway Away if he gets to enter.

At the Trackside Training Center, Blue Grass (G1) runner-up TWINSPIRED (Harlan's Holiday) returned to the track Monday morning for the first time since his final major Derby workout on Saturday. The Mike Maker trainee galloped 1 1/2 miles under exercise rider Derrick Smith.

Twinspired will van across town to Churchill Downs on Tuesday after training hours and complete his Derby Week preparations beneath the Twin Spires, for which he is named. He's owned by Alpha Stables, Skychai Racing and Sand Dollar Stable.

"He came out of the Blue Grass fine and the horse doesn't think he lost, that's the good part," said Maker, who came within a nose of back-to-back wins in Keeneland's signature prep race after winning last year with Stately Victor (Ghostzapper).

"I don't think there are a lot of similarities between Twinspired and Stately Victor other than people saying both had to prove themselves on the dirt. But they're different horses."

Maker remains hopeful that DERBY KITTEN (Kitten's Joy) can draw into the Derby 137 lineup. Owned by Ken and Sarah Ramsey, Derby Kitten ranks No. 21 on the current graded stakes earnings list that determines the starting lineup. Maker said a rider for Derby Kitten remains in limbo.

"If Derby Kitten draws into the race, it's because someone unfortunately had to come out," Maker said. "So we'd obviously look at the rider that became available if something were to happen as one consideration."

Derby Kitten also galloped 1 1/2 miles on Monday at Trackside Training Center.

The three Derby contenders not yet in Kentucky -- TOBY'S CORNER (Bellamy Road), COMMA TO THE TOP (Bwana Charlie) and MASTER OF HOUNDS (Kingmambo) -- are all due to arrive Tuesday.

Dianne D. Cotter's Wood Memorial (G1) winner Toby's Corner jogged at the Fair Hill Training Center in Elkton, Maryland, one day worked six furlongs in 1:15 on the Tapeta surface. He is scheduled to van to Churchill Downs on Tuesday.

Trainer Peter Miller reported that his CashCall Futurity (G1) winner Comma to the Top looked "super" Monday morning at Hollywood Park following his five-furlong drill Sunday that he accomplished in 1:00 2/5.

"He's doing great," Miller said. "We just walked him today and he's got his plane at 4 tomorrow morning (PDT)."

Miller indicated that he'd be flying Monday afternoon from Los Angeles and planned to be on board at Churchill when Comma to the Top makes the scene, probably early Tuesday afternoon.

California-based Patrick Valenzuela – one of four of this year's Derby riders who has won the race previously – has the call on Comma to the Top.

Mrs. John Magnier's Master of Hounds is scheduled to arrive in Louisville between 8 and 8:30 a.m. (EDT) Tuesday and van to Churchill Downs with an arrival time at the quarantine section of Barn 45 between 9 and 9:30 a.m.

The Irish-based colt, trained by Aidan O'Brien, finished second in Dubai's $2 million U.A.E. Derby (UAE-G2) on March 26, in his only start of 2011. Master of Hounds visited Churchill Downs last fall for the Breeders' Cup World Championships, where he finished sixth in the Breeders' Cup Juvenile Turf (G2).

Master of Hounds will be ridden by Garrett Gomez.
