LOUISVILLE, Ky. - Trainer Ken McPeek said Sunday morning that Kentucky Derby winner Mystik Dan is not definite to run in the $2 million Preakness Stakes on May 18 at Pimlico. After taking the traditional morning-after-the-Derby phone call from Pimlico officials inviting the Derby winner to the Preakness, McPeek told the assembled media outside his Churchill Downs barn Sunday morning that he could wait until entry day - May 13 - to decide whether to run Mystik Dan in the Preakness or train up to the Belmont Stakes on June 8. “We’re not committed to the Preakness, no, not yet,” McPeek said. “I ran him back once in two weeks and it completely backfired on me and we skipped the Rebel because it was back too quick.” Last November, Mystik Dan ran fifth in an allowance race 13 days after he won his maiden at Churchill. On Feb. 3, Mystik Dan won the Southwest Stakes by eight lengths but skipped the Rebel on Feb. 24 and awaited the Arkansas Derby on March 30, when he finished third. McPeek said Mystik Dan “left three quarts of feed” Saturday night. “If he’s not in the feed tub, he won’t run and he ran hard yesterday, but we’ll see,” McPeek said. On Saturday, Mystik Dan got a dream trip under a brilliant ride from Brian Hernandez Jr. and just had enough to hold off the oncoming Sierra Leone and Forever Young to win the 150th Kentucky Derby by a nose over Sierra Leone, who was a nose in front of Forever Young. :: Subscribe to the DRF Post Time Email Newsletter: Get the news you need to play today's races!  “Brian Hernandez, what a ride!” McPeek said. “I mean incredible. He doesn’t win the race without the job Brian did.” McPeek and Hernandez also teamed to win Friday’s Kentucky Oaks aboard Thorpedo Anna. That made them the first jockey-trainer duo to win both races since Eddie Arcaro and Ben Jones did it in 1952. McPeek won his first Oaks and Derby this weekend. Back in 2002, he ran the favorite in the Oaks in Take Charge Lady and the favorite in the Kentucky Derby in Harlan’s Holiday, the two finishing second and seventh, respectively. “That year we had a chance to do this; to actually pull this off was amazing,” McPeek said. “But there’s always work to do, there’s a team of people that depend on me to give them direction so you can’t rest on your laurels too long.” Mystik Dan, a son of Goldencents owned by his breeders Lance and Sharilyn Gasaway, Daniel Hamby and 4G Racing as well as Valley View Farm, earned a 100 Beyer Speed Figure for his Derby victory. McPeek said he has not ruled out the Belmont Stakes for Thorpedo Anna. Though she is not nominated to the Triple Crown, it would cost $50,000 to supplement her to the Belmont compared with $200,000 to supplement to the Preakness, something McPeek has already ruled out. McPeek said he would not run both Mystik Dan and Thorpedo Anna in the Belmont. As of Monday, the only runner from the Kentucky Derby confirmed to run back in the Preakness was Just Steel, who finished 17th after being part of the early Derby pace and fading.  Trainer Chad Brown said runner-up Sierra Leone would ship to Saratoga on Monday to prepare for the Belmont. Brown said Sierra Leone came out of the Derby more tired than he had in his previous races this year, victories in the Risen Star at Fair Grounds and the Blue Grass at Keeneland. Sierra Leone, who under Tyler Gaffalione had to rally from 17th position, and Forever Young, who was also way back early on, exchanged several bumps in the stretch as Sierra Leone continued his habit of lugging in during the stretch of his races. It appeared Gaffalione was trying to move Forever Young off him with his left hand but Brown said Gaffalione was trying to make room to use his left-handed crop. “What Tyler was attempting to do was make room for his left stick which the horse really respects and keeps him straight and [he] was looking for a pathway to use his left stick,” Brown said. “With the bumping and the tight duel between the two horses, it disarmed him with the stick, all he had was a rein to pull on and it really hurt his momentum.” There was no stewards’ inquiry into the bumping incident and jockey Rusei Sakai on Forever Young did not claim foul. “I didn’t feel a foul was committed - to me - and I understand what [Gaffalione] was attempting to do and I understand what the other horse was attempting to do,” Brown said. “In my mind I think they know they don’t want him to use his stick.” Hiroshi Ando, the stable manager for the owners of Forever Young, said Sakai did not think the bumping warranted lodging an objection. “I spoke to the jockey after the race, he didn’t plan to claim [foul] because both horses were fighting together,” Ando said. “We wanted to win, we couldn’t make history, but we’re really proud of our horse.” Forever Young, who suffered his first career defeat from six starts in the Kentucky Derby, was scheduled to ship back to Japan on Tuesday along with T O Password, another Japan-based runner who finished fifth. Catching Freedom, who finished fourth in the Kentucky Derby, has not been ruled out of a Preakness start, trainer Brad Cox communicated. “I’ll know more in a few days,” Cox texted. Trainer Bill Mott said Resilience, the sixth-place Derby finisher, would not run in either of the next two legs of the Triple Crown, saying the distance is too far for him. Stronghold, seventh in the Derby, was to return to California and point to 3-year-old stakes later in the year, trainer Phil D’Amato said. Honor Marie (8th) and Dornoch (10th) are likely to train toward the Belmont Stakes. Endlessly, who finished ninth in the Kentucky Derby, is likely to return to the turf, with the Grade 1, $750,000 Belmont Derby on July 6 at Aqueduct a target. Fierceness, who finished 15th in the Kentucky Derby as the favorite, was expected to ship to Saratoga and train toward a possible start in the Belmont Stakes. As far the Derby was concerned, trainer Todd Pletcher said Fierceness hopped at the start, but he still felt John Velazquez got the horse into the desired spot, albeit a little wide, into the first turn. “I thought he was able to get into his rhythm,” Pletcher said. “Johnny took a peek over his shoulder midway down the backside, which is usually a pretty good sign, but when he hit the go button, he went 20 yards and came off the bridle.” Pletcher said he did not see anything physically amiss with Fierceness. The Bob Baffert-trained pair of Muth, who beat Mystik Dan in the Arkansas Derby, and Imagination, the Santa Anita Derby runner-up, head the list of Preakness runners.  Other possibles include Copper Tax, winner of the Federico Tesio, Seize the Grey, the Pat Day Mile winner, Informed Patriot, the Bathhouse Row Stakes winner, Uncle Heavy, the Withers winner, and Tuscan Gold, third in the Louisiana Derby. Uncle Heavy and Tuscan Gold could both be entered Wednesday in Saturday’s Grade 3 Peter Pan Stakes at Aqueduct, but their connections said they are monitoring the Preakness. :: Want to learn more about handicapping and wagering?
