LOUISVILLE, Ky. &ndash; Funny how that works. Purses at Churchill Downs have undergone a couple of double-digit increases in recent weeks, and now a second-level allowance worth $67,500 has attracted an oversubscribed field of extremely well matched horses, exemplifying how such a formula can work to the advantage of horseplayers.\r\nLet&rsquo;s Do It, one of a small string of horses that Graham Motion left here after he won the May 7 Kentucky Derby with Animal Kingdom, is one of the logical favorites in the ninth of 10 Sunday races, a 1 1/16-mile turf race for 3-year-olds and up. A 4-year-old El Prado colt, Let&rsquo;s Do It most recently was a stretch-running second for this identical condition May 20, when the purse was $52,267 and only eight started.\r\nJulien Leparoux will take the mount on Let&rsquo;s Do It when the colt breaks from post 5. Twelve others are entered, although also-eligible Screen Play will make the race only in the case of a scratch.\r\nSeveral horses scheduled to break near Let&rsquo;s Do It are among his main rivals: King&rsquo;s Command (post 4, Robby Albarado), Joes Blazing Aaron (post 6, Jesus Castanon), and Almoradi (post 8, Miguel Mena).\r\nKing&rsquo;s Command, trained by Neil Howard, showed real grit in getting through his first allowance condition in his last start, the third in his form cycle. The 4-year-old son of Empire Maker owns the tactical speed that could serve him well in a race that shouldn&rsquo;t lack for pace.\r\nJoes Blazing Aaron is the main reason a quick tempo appears likely. Since Florida-based breeder-owner Joseph Witek sent the speedy colt to Kentucky and trainer Mike Maker, Joes Blazing Aaron has set the pace before fading in a pair of contentious stakes and now figures to stay longer out front, given the drop back into allowance company.\r\nAlmoradi, trained and co-owned by Eddie Kenneally, appreciated the wakeup call that a $50,000-claiming berth on June 3 afforded him as he did everything perfectly in asserting his class. The 5-year-old son of Barathea sports a number of Beyer Speed Figures that would make him very competitive here.\r\nOne other allowance (race 4) also is carded for Sunday. It&rsquo;s a $62,100, first-level, seven-furlong race that drew six 3-year-old fillies, led by Henny&rsquo;s Hurricane, who scratched from the Dogwood Stakes two weeks ago to run fifth instead in a small Prairie Meadows stakes. Leparoux rides for trainer Ken McPeek.\r\nAfter Sunday, Churchill goes dark for three days before live action resumes Thursday. First post both days is 12:45 p.m. Eastern.\r\nChurchill purses underwent a 10 percent increase June 3 and another 15 percent hike Thursday. The 39-day spring meet ends July 4.
