Wrona takes over race-calling


Turf Paradise fans can always tell when the Kentucky Derby is getting close. That's because track announcer Luke Kruytbosch is also the regular voice of Churchill Downs and the Kentucky Derby. So Kruytbosch is off to Churchill Downs, after a three-day fill-in stint for Vic Stauffer at Gulfstream Park. And Michael Wrona is set to take over as track announcer at Turf Paradise on Friday. Wrona, from Australia, previously was the racecaller at Lone Star Park and has also called the races at Santa Anita.

Meanwhile, just seven months after winning his first race, on September 2004 at Kentucky Downs, apprentice rider Kyle Kaenel, son of "Cowboy" Jack Kaenel, rode his 100th winner on Sunday here.

"I'm hoping for a couple hundred more," he said.

After riding two winners Monday, Kaenel, 17, was seven behind jockey standings leader Wilson Dieguez, who had 103 wins. Kaenel will stay at Turf Paradise until Arlington Park opens this summer.

Desert Prospector's stakes double

Desert Prospector's 3 1/2-length win in the Arizona Stallion Stakes Saturday gave the son of Big Sky Chester back-to-back stakes wins.

"We'll head next to the [Arizona] Breeders' Derby," said Desert Prospector's trainer, Bart Hone. The 1 1/16-mile derby is held on Arizona Thoroughbred Breeders' Day, April 30. Hone, who trained Desert Prospector's sire, added, "We have a batch of 'Big Sky' babies in the barn looking to debut in the fall."
