Allowance sprint tough to figure

EmailMIAMI - Friday's $28,000 main event figures to pose an intriguing test for handicappers, who will be hard pressed to toss any of the six 3-year-old fillies who make up the starting lineup for the six-furlong second-level allowance dash.

Four of them - Lucky Too, High Altitude, Sweet Yamila, and Silver Envoy - are coming off a victory, while both Mountain Tiger and Secret Girlfriend are a single start removed from a first-level allowance win.

Silver Envoy will be in new hands Friday, having been claimed by trainer Kirk Ziadie for $40,000 off a 10 3/4-length triumph Sept. 9. Ziadie is sporting a sensational 50 percent success rate with his new acquisitions, and Silver Envoy is perfect in two starts since putting blinkers on and beating older optional claiming foes in wire-to-wire fashion on Aug. 12.

High Altitude, Silver Envoy's former stablemate under the shed of trainer Steve DiMauro, will also shorten up after winning going a mile in her last start on Aug. 30. High Altitude, a daughter of Mount McKinley, has been in front in each of her last three outings but does not figure to see the lead turning back to six furlongs.

Lucky Too and Secret Girlfriend may vie for the early advantage. Lucky Too returned from an 11-month layoff earlier this month to run the best race of her career, rushing to command following a slow start and drawing out to a six-length decision over older first-level optional claiming foes.

Secret Girlfriend will benefit from a switch to the outside post after being victimized by tardy beginnings from the rail in each of her last two appearances. Despite breaking last, Secret Girlfriend recovered to post a win and a second in those races for owner-breeder Maurice Miller and trainer Bill White.

Mountain Tiger and Sweet Yamila will be the major beneficiaries if a speed duel develops. They both rallied from near the rear of the pack to finish first and second in a first-level allowance on Aug. 27. Mountain Tiger stepped up off the win to finish fourth against older rivals 18 days later, while Sweet Yamila rebounded with a last-to-first allowance win on Sept. 13.

$2.3 million yearling to debut

Friday's seventh race will mark the career debut of A.P. Magic, a 3-year-old daughter of A.P. Indy who was purchased for $2.3 million out of the 2005 Keeneland yearling sale by Sheikh Mohammed al-Maktoum's chief bloodstock adviser, John Ferguson. A.P. Magic, who is out of the two-time Grade 2-winning mare Magicalmysterycat, is owned by Bethsheba and Alphonso Bowe and trained by Jorge Romero.

A.P. Magic will enter Friday's contest, a six-furlong maiden special weight dash, showing just two works: a half-mile in 53 seconds and three furlongs in 38.20 at the Starting Point Training Center in Ocala, Fla.

Gulfstream simulcast wagering up

Gulfstream Park has shown a marked increase in simulcast wagering since being allowed to simulcast races during the day for the first time last Saturday. Gulfstream handled $115,594 last Saturday compared to $33,585 the previous Saturday, and $84,646 on Sunday compared to $19,018 the previous Sunday.
