Mark Casse has become arguably the preeminent trainer at Woodbine in Canada, where the main racing surface has been Polytrack since August 2006. With more than 400 wins at Woodbine since 2007, Casse clearly knows how to prepare a horse to win over a synthetic track, and that’s just what he has been busy doing lately with a colt named Stealcase.

Lucky Chappy will add to his gaudy number of frequent-flier miles when he starts in the Group 2, $2 million UAE Derby at 1 3/16 miles over the Tapeta surface at Meydan on March 31. An Irish-bred colt raced by the Animal Kingdom connections of Team Valor International and trainer Graham Motion, Lucky Chappy began his career in Italy, competed on both coasts in his four-race North American campaign, and, if all goes right in Dubai, will return to Churchill Downs on the first Saturday in May for a run in the Kentucky Derby.

HOT SPRINGS, Ark. – Secret Circle will attempt to complete a sweep of Oaklawn Park’s series for 3-year-olds next month, when he runs in the Grade 1, $1 million Arkansas Derby.

Earlier in the meet, Secret Circle captured the second and faster division of the Grade 3, $250,000 Southwest Stakes.

LOUISVILLE, Ky. – Juvenile champion Hansen breezed an easy half-mile in 50.40 seconds at Churchill Downs Trackside on Sunday in preparation for the Grade 1 Wood Memorial on April 7 at Aqueduct. The work marked his first breeze since taking the March. 3 Gotham Stakes at Aqueduct.

With exercise rider Joel Barrientos aboard, Hansen breezed comfortably while never being asked for speed over a fast but drying-out racetrack. He went evenly, with Daily Racing Form timing him galloping out five furlongs in 1:06.20.

HOT SPRINGS, Ark. - Secret Circle handled the latest distance test in his escalating career Saturday at Oaklawn Park, when he beat a fast-closing Optimizer by three-quarters of a length in the Grade 2, $500,000 Rebel Stakes.

OZONE PARK, N.Y. – Street Life likely earned himself a spot in the $1 million Wood Memorial by overcoming a slow pace to run down pacesetting Copy My Swagger to win Saturday’s $75,000 Broad Brush Stakes by one-half length at Aqueduct.

The win was the second straight for Street Life, a son of 2007 Kentucky Derby winner Street Sense, after he finished eighth in his debut at Gulfstream on Jan. 5.

Under Junior Alvarado, Street Life raced in fourth position about 3 1/2 lengths off the pace of Copy My Swagger, who ran a half-mile uncontested in 48.76 seconds.
