MIAMI - Marty Wolfson and Joe Calascibetta have been saddling winners here this spring at a 33 percent clip, and leading trainer Kirk Ziadie is maintaining a near 30 percent success rate for the meet. But they all pale in comparison to the 60 percent mark trainer Myra Mora has posted, with 6 victories from just 10 starters during the first 29 days of the current session.

Mora, who won only seven races in all of 2007, admitted she is as surprised as anyone about the success she's had since her arrival here from Tampa Bay Downs early in the meet.

BOSSIER CITY, La. - While jockey Patrick Valenzuela's latest comeback has garnered considerable attention at the Louisiana Downs meet, fellow rider Francisco Torres also has battled back from drug abuse. While Valenzuela had won 1 race from 19 mounts at the meet entering Thursday's card, Torres found himself on top of the rider standings with 12 wins from 61 mounts.

LOUISVILLE, Ky. - This week, it's Curlin's turn.

Everybody knows what happened last week when Big Brown took his turn in the Belmont Stakes.

"Big Brown's Belmont is a very good indication that nothing is a foregone conclusion in this game," said Steve Asmussen, who on Saturday will saddle the reigning Horse of the Year, Curlin, for the Grade 1 Stephen Foster Handicap at Churchill Downs.

Model's Memo stormed from last through the final turn and closed down the middle of the track in the stretch to take Monday's $50,000 Indiana First Lady Stakes by a widening 2 1/4 lengths at Indiana Downs.

The race was switched from a mile on turf to a mile and 70 yards on the main track at after rain earlier in the card. Model's Memo, a 3-year-old ridden by Orlando Mojica for trainer Tom Drury, covered the distance in 1:45.42 over the sloppy going and returned $6.60 as the 2-1 favorite in the field of 12 Indiana-bred fillies.

All-sources wagering on races at the Pimlico Race Course meet that ended Sunday plummeted 17.9 percent compared with last year, according to figures provided by Pimlico on Tuesday.

Average daily all-sources wagering on the track's races for the 31-day meet was $4,380,645, compared with $5,338,710 during the 31-day meet last year. Total wagering fell from $165.5 million to $135.8 million.

Churchill Downs planned to offer an experimental betting format using fractional pricing to ontrack customers beginning Wednesday in what is being described as a test, the company said Monday.

The bet, called the Matrix, will allow patrons to select three horses for a minimum of $9. The bet will pay off if one of the selections wins, if two of the selections fill out the exacta, and if the three selections fill out the trifecta, in any order.

INGLEWOOD, Calif. - When a good horse runs as badly as Champs Elysees ran Saturday in the Grade 1 Charles Whittingham Handicap, usually there is an explanation. Favored at 4-5 in the 1 1/4-mile turf race at Hollywood Park, Champs Elysees failed to reach contention and finished sixth of seven runners. It did not take long to discover the reason why.

"I hate to make excuses, but he was sick," trainer Bobby Frankel said. A

postrace endoscopic exam revealed excessive mucus. Blood tests revealed a high white count. Frankel was both disappointed and relieved.

ARLINGTON HEIGHTS, Ill. - With a victory on Saturday at Arlington Park, Earlie Fires became the ninth-leading rider in racing history in terms of wins. More surprising is the fact that through Sunday's racing, Fires was tied for fourth in the jockey standings at the current Arlington Park meet.

AUBURN, Wash. - Victorina was very much as advertised in Sunday's $50,000 Washington State Legislators Handicap, which is to say she was classy and fast.

Though trainer Greg Gilchrist, watching via simulcast at Golden Gate, professed to be concerned when Victorina fell 3 1/2 lengths behind pacesetters She's All Silk and Private Dreams after a quarter-mile in 22 seconds, there was little doubt that Victorina would win once rider Kevin Radke asked her to run on the turn. And win she did, scoring by more than a length over the fast-finishing Beaulena in 1:15.40 for 6 1/2 furlongs.

Trainer Eric Heitzmann has come to Louisiana Downs by way of Dubai, and in his first season at the Bossier City, La., track he is sitting second in the standings to Jerry Cart. Heitzmann is 5 for 11 with his starters this meet and had a double Sunday with Exciting Empress ($4.20) and Autobeacat ($19.60).

"We had a good day," he said.

Heitzmann, 39, is a Louisiana native who has spent a good deal of his racing career in Dubai. He returned to North America in late 2006 after spending seven years working as an assistant to French trainer Erwan Charpy in Dubai.
