I'm very happy with him.&quot;\r\nSantiva is one of at least 13 3-year-olds expected when entries for the 1 1/8-mile Polytrack race are taken Wednesday. As many as 14 can start.\r\nKENTUCKY DERBY NEWS: Track all the 3-year-olds on the Triple Crown trail\r\nTwo other Blue Grass hopefuls also tuned up Saturday: Willcox Inn, with Rosie Napravnik up, went six furlongs, handily, in 1:12.40 in company over the Keeneland Poly, while Joes Blazing Aaron breezed five furlongs in 59.80 seconds over the dirt surface at the Trackside training center in Louisville.\r\nOther tentatively scheduled Blue Grass works include the Todd Pletcher trio of Queen&rsquo;splatekitten, Sensational Slam, and Praetereo at Churchill Downs on Sunday, and King Congie at Keeneland on Monday with Rajiv Maragh aboard.\r\nThe Blue Grass anchors by far the busiest week of stakes at the 15-day spring meet. Thursday brings the Grade 1 Vinery Madison; Friday is the Grade 1 Maker&rsquo;s Mark Mile; the Blue Grass undercard also includes the Grade 2 Commonwealth, Grade 2 Jenny Wiley, and Grade 3 Shakertown; and Sunday wraps it up with the Grade 2 Beaumont.\r\n◗ Casper&rsquo;s Touch earned a Beyer Speed Figure of 78 in winning a first-level allowance Friday, opening day, by three lengths. Trainer Ken McPeek said the colt could run back in 15 days in the April 23 Coolmore Lexington Stakes or wait an extra week for the Derby Trial on opening night at Churchill. Both are Grade 3 races worth $200,000.\r\n◗ The first pick five wager ever offered at Keeneland drew a handle of $82,593 on opening day, a solid amount in consideration of its newness.

All-sources handle was $8,117,921.\r\n◗ The start of the last race Friday was delayed by about eight minutes after a would-be first-time starter named Miss Reve, who was 77-1 at the time, disrupted things by acting up badly in the gate, necessitating her being a late scratch.
