L Da Vinci fits potent pattern

EmailMIAMI - Remarkable is a word that may not do justice to describe the success Kirk Ziadie has had over the last couple of seasons with horses making their first start off a claim. On Friday, Calder's leading trainer will attempt to add to his already imposing statistics in that category when he sends out L Da Vinci in the featured ninth race, a $16,000 optional claimer at a mile and 70 yards.

Of the last 30 horses Ziadie has claimed, 14 - an astounding 47 percent - have won their next start. His prowess at the claim box includes Paradise Dancer and Blue Pepsi Lodge, both of whom won stakes races here this past weekend.

Ziadie haltered L Da Vinci in the name of the Acclaimed Racing Stable for $10,000 on Nov. 24. The 4-year-old L Da Vinci finished second, beaten 1o1/4 lengths, going a mile that day. In his previous start, L Da Vinci won a $6,250 claimer, earning a 94 Beyer Speed Figure that was 16 points higher than his previous career best in 2006.

He will return for a $16,000 price tag under the optional claiming conditions of Friday's race, which is also open to first-level allowance horses, and figures to stand some catching if he breaks alertly from his inside post under leading rider Manoel Cruz.

L Da Vinci should receive his sternest challenges from Marnesia's Big Boy and New York invader Comprise.

Marnesia's Big Boy has not started since being outgamed by a nose following a stretch-long battle under straight entry-level allowance conditions on June 7. He has worked forwardly for his return over the past six weeks.

Comprise receives a little class relief after knocking heads with much more expensive optional claiming foes for much of the summer and fall in New York. Trained by Nick Zito, Comprise seeks his first win since he scored in a maiden race at Gulfstream Park on March 24.

* Nominations for the first two stakes of the Gulfstream Park meet, the $75,000 South Beach and $100,000 Canadian Turf Handicap, close on Friday. The South Beach will be decided opening day, Jan. 3, while the Grade 3 Canadian goes the following afternoon. Both races are 1 1/16 miles on turf.
