Ridden by Rafael Bejarano, the gray or roan Theonewewaitedfor made or pressed the pace from the start of the 5 1/2-furlong race and drew clear in the stretch to win by 2 3/4 lengths over 7-10 favorite Miss Southern Miss in the final time of 1:03.82. Demigoddess finished third. Theonewewaitedfor was the 3-1 second choice in the six-horse field.

On July 3, Live Oak Stud’s homebred World Approval won the Grade 1 United Nations Handicap at Monmouth Park, and while it was not his first stakes win – so there was nothing new there – his victory in the $300,000 event pushed him closer to the $1 million mark in earnings. With that victory, World Approval (by Northern Afleet) increased his earnings to $853,450 – and he’s just 4, and just getting started by most measures when looking at his siblings.

Zenyatta, the 2010 Horse of the Year, was confirmed by her connections on Thursday to be in foal to Medaglia d’Oro for 2017.

LEXINGTON, Ky. – Kentucky Derby winner Animal Kingdom, whose first foals born in the Southern Hemisphere will race in the 2016-2017 season, will not be standing at stud in Australia this year in order to rest from dual hemisphere shuttle duties the past three years.

Animal Kingdom will remain at Darley in Lexington after he completes the current breeding season. The son of Leroidesanimaux had stood at Arrowfield in Scone, Australia, the past three years and will return to that farm for the 2017 breeding season.

The American experiment with synthetic surfaces did not end well. While it is arguable that the synthetic alternative was oversold and adopted in some venues without much aforethought, it is pretty much inarguable that those surfaces achieved their stated objective of reducing catastrophic front leg injuries, though they may have increased less catastrophic injuries in other parts of the equine anatomy.

Champion sprinter Cherokee Run, who went on to sire a pair of champions, has been euthanized due to declining health in his advanced age. Cherokee Run, a son of Runaway Groom, was 26.

Cherokee Run entered stud at Jonabell Farm, which was then owned by the Bell family, in 1996, and became a Darley stallion after the facility was purchased by Sheikh Mohammed in 2001. The stallion continued to call the Darley stallion barn home after being pensioned in the fall of 2009, residing alongside fellow pensioners Holy Bull (25) and Quiet American (30).
