Stallion favorites look tough

Coming off a dominant 7 1/4-length win in the Desert Vixen (above), Running Lass will be odds-on against many of the same rivals.

MIAMI - Can anybody beat In Summation and Running Lass, or are both youngsters on the path to an unprecedented double sweep in this year's Florida Stallion Stakes?

Those questions will be answered along with many others on Saturday's Juvenile Showcase Card at Calder, a unique 14-race program consisting entirely of 2-year-old races. The card is highlighted by the $125,000 Affirmed and Susan's Girl divisions of the Florida Stallion Stakes, both at seven furlongs.

In Summation and Running Lass dominated their respective divisions in the opening round of the Stallion Stakes three weeks earlier and will be heavily favored to win again on Saturday.

won for the fourth time in as many tries when he cruised to a six-length victory over B L's a Runner in the six-furlong Dr. Fager Stakes on Aug. 13. A son of Put It Back, In Summation's only real test came in his previous start, when he was extended by The Pharaoh before posting a 1 1/4-length decision in the Birdonthewire Stakes. In Summation earned a 100 Beyer Speed Figure for his performance over a sloppy track in the Dr. Fager.

About the only question mark hovering over In Summation as the stallion series continues is the added distance. But trainer Frank Gomez remains unfazed by the prospect of stretching out his undefeated colt.

"He's been winning so easy, I think he'll go further," said Gomez. "He proved he could rate when he won the Birdonthewire - not that anybody has more speed than he does."

In Summation figures to again be on or with the pace in the Affirmed, especially since he drew the outside post in a field of nine 2-year-olds. Regular rider Manoel Cruz retains the mount.

In Summation will face several new and potentially dangerous foes in the Affirmed, among them recent maiden winners Lucky Chief, Blazing Rate, Thanks Dubya, and D J Best. The remainder of the lineup is Saint Jules, Old Town Pond, and Forever Fear.

, a $220,000 purchase at this winter's Ocala Breeders' Sales Co. auction at Calder, bounced back from a third-place finish in his debut to register a two-length victory on Aug. 20 while easily handling seven furlongs, the same distance as the Affirmed. A son of Delaware Township, Lucky Chief received an 88 Beyer for the effort.

"He had a rough trip the first time after breaking slow from the rail," said trainer Eddie Plesa Jr. "Frank's horse figures to be pretty salty on Saturday, and I'd much prefer to have another week between races, but this is the logical spot and he'll have plenty of time until the last race in the series after this one."

The last leg of the Florida Stallion Stakes is the $400,000 In Reality on Oct. 15.

also received an 88 Beyer when posting a 5 3/4-length maiden special weight victory in his career debut on Aug. 13. But trainer Richard Root cautions that that race was at five furlongs, and going seven furlongs on Saturday is a different ballgame.

"In Summation has already won four races, Eddie's horse has already won going seven furlongs, and we're going from five-eighths to seven-eighths," said Root. "But he's training aggressively and I think he'll handle the extra distance, so we'll give it a shot and see what happens."

When goes postward as the odds-on favorite in the seven-furlong Susan's Girl, she will face much of the same competition that she dominated by 7 1/4 lengths in the Desert Vixen on Aug. 13. Three of her six rivals on Saturday exit that race, including runner-up Siren Cove, who figures to relish the added distance and improve off just the second start of her career.

The most interesting of the new faces is , a speedy daughter of Formal Dinner who led throughout to win her maiden at first asking by 4 1/4 lengths over the heavily favored Lake Alice on the Desert Vixen undercard.
