Where will Unbridled Sidney run?


MIAMI - Turf and 2-year-olds will dominate the early portion of Saturday's $2 million Summit of Speed program at Calder.

Five-furlong turf specialists will get an opportunity to earn a big payday in the $100,000 Bob Umphrey Turf Sprint Handicap and the $100,000 Distaff Turf Sprint Handicap for fillies and mares. Juveniles of both sexes run for the same money in the 5 1/2-furlong Criterium Stakes and its filly counterpart, the 5 1/2-furlong JoJ'sdream.

Trainer Ronny Werner may hold the key to both the Bob Umphrey and Distaff Turf Sprint, depending upon where he decides to run his fleet 6-year-old mare Unbridled Sidney, who is entered in both races.

Unbridled Sidney has won three of her last five starts, all in gate-to-wire fashion, including this track's richest turf race, the $250,000 Distaff Turf Sprint Championship, 11 months ago. She defeated males in the Cherokee Run Breeders' Cup at Churchill Downs to close out her 2006 campaign.

If she runs against her own kind in the Distaff Turf Sprint, Unbridled Sidney will have to deal with the equally swift Smitty's Sunshine, who brings a five-race win streak into the contest. The Louisiana-based Smitty's Sunshine is perfect in three starts this season, her most recent tally an easy 2 1/4-length decision over a yielding surface in Churchill's Mamzelle Stakes on May 3.

Other top contenders in the Distaff Turf include Flying Circle, who finished a troubled third in the Mamzelle, and the former claimer Charlie Papa, who has won her last seven starts dating back to October 2004.

If Werner opts to try Unbridled Sidney against the boys, she will go up against a field that includes locals Lord Robyn, Jet Propulsion, and Nacascolo.

Lord Robyn appears to be cycling back to his peak form while showing more speed than he had throughout most of the 2006 campaign. He was on the pace throughout to capture the Reappeal Stakes here May 12, then finished second as the 3-5 favorite behind Nacascolo after being hung wide throughout in the Heckofaralph Stakes four weeks later.

Jet Propulsion tries five furlongs on the grass for the first time in his career. He has not started since upsetting the Grade 3 Miami Mile BC Handicap in wire-to-wire fashion on April 28.

Most of the better locally based 2-year-olds will be on display in the Criterium and J J'sdream.

The Criterium will be led by stakes winner Brother Joey and the undefeated Honey Honey Honey, who handed Brother Joey his only loss in three starts when both debuted on May 12.

Honey Honey Honey was an easy winner in the pair's first meeting, leading throughout en route to a four-length decision. Brother Joey rebounded from that setback to post a pair of victories, including a game nose decision over Casino Gambler in the B L's Sweep Stakes on June 16.

Casino Gambler, who will race coupled in a Stanley Gold-trained entry along with Honey Honey Honey in the Criterium, will get Lasix for his rematch with Brother Joey.

Other top contenders include Big City Man, an easy maiden winner in his last start, and Kentucky invader High Bridled.

Yonagucci, an impressive winner of her only start, and Excessive Heat are the ones to beat in the J J'sdream.

Yonagucci drew off to an easy 8 3/4-length victory going 4 1/2 furlongs when debuting over a wet track on June 2, and has continued to train splendidly since that outing.

Excessive Heat won her career bow going a quarter-mile at Santa Anita, ran poorly over Hollywood Park's synthetic surface in the Cinderella Stakes, then shipped here to dominate first-level allowance horses by five lengths while winning with speed to spare here on June 22.
