Wallenda, a Grade 1 winner, sire, and resident of Old Friends Equine Retirement in Georgetown, Ky., was euthanized Monday afternoon after long-running hoof and suspensory issues rapidly worsened.

The 26-year-old was the most successful runner from the first crop of his sire Gulch, who was himself a longtime Old Friends pensioner and died in January. Wallenda had resided at Old Friends since April 2007.

The small-scale but quality operation Hinkle Farms pulled off a Grade 1 double Saturday at Churchill Downs, with Nyquist taking the Kentucky Derby and Divisidero winning the Woodford Reserve Turf Classic. The dams of both horses reside in the farm’s broodmare band of about 30.

Two-time Horse of the Year Curlin, who had already established himself as a prominent source of classic stamina, put another feather in his cap last Saturday with Kentucky Derby runner-up Exaggerator.

Nyquist, the Kentucky Derby winner and 2015 champion juvenile male, could have been had by anyone willing to be the highest bidder on three separate occasions.

Uncle Mo was already the hottest young sire on the planet before the first Saturday in May, but just how much hotter will he get after Nyquist’s victory in the 142nd Kentucky Derby? Does any doubt remain that Uncle Mo is the real deal?

One of the biggest winners of the Kentucky Derby and Oaks weekend didn’t run a horse in either of the marquee races.

Sheikh Mohammed al-Maktoum’s Darley America picked up another big win for its stallion roster Friday when Cathryn Sophia, a daughter of Street Boss, drew away to win the Kentucky Oaks. The following day, future Darley resident Nyquist took home the roses as the favorite in the Kentucky Derby.

One of the earliest and best racehorses based in the United States for the sprawling international operation of Sheikh Mohammed bin Rashid al Maktoum was Street Cry. The Irish-bred son of Machiavellian (by Mr. Prospector) started his career in California with Eoin Harty, running third in the 2000 Breeders’ Cup Juvenile before being turned over to Saeed bin Suroor and developing into one of the best older horses in the world, taking the Dubai World Cup in 2002 and following with a tour-de-force win in the Grade 1 Stephen Foster Handicap.

Nyquist was an unbeaten juvenile champion, just like his sire, and was made the morning-line favorite for the Kentucky Derby, just like his sire. The question was, could he go the classic distance, something his sire had never done?

The answer was a resounding yes. Nyquist remained undefeated in eight starts with an emphatic victory in the Kentucky Derby last Saturday at Churchill Downs, giving the outstanding young sire Uncle Mo a classic winner from his first crop.

Gold Rush Dancer may turn out to be something when he grows up.

On May 1 at Golden Gate Fields, Gold Rush Dancer won his second stakes – and his first in California – in the $100,000 Silky Sullivan Stakes for California-bred 3-year-olds at a mile on turf. Owner and breeder John Parker, of Washington state, said Gold Rush Dancer won despite showing signs of immaturity.

“I guess he’s green, and the jockey said he likes to look around,” he said on Friday.
