When he was an assistant to Bobby Frankel, trainer Chad Brown was around Leroidesanimaux, the turf star now better known as the sire of Animal Kingdom, the Kentucky Derby winner.\r\n&ldquo;He was a real tough horse,&rdquo; Brown recalled Wednesday. &ldquo;That horse, he always trained well on dirt, but he was on such a roll on the turf that we kept him on it. So it didn&rsquo;t surprise me that Animal Kingdom liked it.&rdquo;\r\nBrown has a closer rooting interest regarding Leroidesanimaux here at Pimlico on Friday. He will send out Ms Silver Oak, a daughter of Leroidesanimaux, in the $75,000 Hilltop Stakes for 3-year-old fillies. The 1 1/16-mile grass race is the last of 13 on the card.\r\nMs Silver Oak is returning to the turf after a good third-place finish on Polytrack at Keeneland. In her race before that, she defeated maidens at Gulfstream Park.\r\n&ldquo;I thought her race on Polytrack wasn&rsquo;t too bad, but she&rsquo;s better on turf,&rdquo; Brown said. &ldquo;She&rsquo;s been consistent. She&rsquo;s steadily gotten better for us.&rdquo;\r\nBrown also entered Celestial Kitten, but she landed the outside post of the 14 entered. Brown said she would &ldquo;most likely&rdquo; be scratched and instead run in the Sands Point at Belmont Park.\r\nAnandi, a powerful winner of her lone outing at Tampa despite a poor start, is among the other top candidates in the Hilltop.\r\nSubpoena had a tough trip in the Edgewood Stakes at Churchill Downs two weeks ago and finished in front of Ms Silver Oak in a Gulfstream allowance in her prior start.\r\nFrontside comes off a front-running win against maidens at Gulfstream and will be making her first start since moving to trainer Mark Shuman&rsquo;s barn.
