With a bevy of stakes races for juveniles around the country over the weekend, three prominent sires each recorded a milestone victory.

Two-time Eclipse Award champion Monomoy Girl will be bred to two-time reigning leading sire Into Mischief in her first season as a broodmare, Spendthrift Farm confirmed Monday.

Appropriately, a deeply rooted Illinois-bred captured what is expected to be the final race in the storied history of Arlington Park on Saturday evening. Sister Ruler, who is stakes-placed at Arlington, captured an allowance turf sprint for fillies and mares to close out the program.

Richard L. Golden, one of the founders of nationally prominent Northview Stallion Station in Maryland, died of natural causes in West Palm Beach, Fla., on Sept. 18. He was 82.

Golden, a native of the Bronx, purchased an undeveloped property in Chesapeake City in 1986 and created Sycamore Hall Farm, which was successful in turning out dozens of Maryland-bred stakes winners. Just two years later, he was part of the team that stepped in to create Northview Stallion Station, located just a mile down the road from Sycamore Hall.

LEXINGTON, Ky. – Consignor James M. Herbener Jr., whose operation is active at the Keeneland September yearling sale, died Sunday morning at his home in Georgetown, Ky., from a suspected heart attack. He was 69.

Herbener’s agency sold a pair of horses at Keeneland September’s Sunday session, an $80,000 Arrogate filly and a $70,000 Nyquist filly. His consignment has five horses remaining to offer this week, and Herbener’s daughter, Heather, along with longtime friend John Williams will handle those duties.

Grade 1 winner Basin has been retired and will enter stud at Spendthrift Farm in 2022.

Shadwell Stud announced Thursday that it will disperse some of its stock following the death in March of its founder, Sheikh Hamdan bin Rashid al-Maktoum.

Shadwell, founded in 1980, released a statement on Thursday saying it is “undertaking a full review of all its activities that will result in important changes for the business.”

“As a result,” the statement said, “its operations in the UK, Ireland and the USA will contract, with a focus on quality and competition at the highest level of the sport.”

The all-turf meet at Kentucky Downs in September offers lucrative opportunities, and next year it will offer even more for horses who pass through the upcoming Keeneland September yearling sale.

Graduates of this year's sale, which runs Sept. 13-24 in Lexington, Ky., will be eligible to run in two $250,000 allowance races at the 2022 Kentucky Downs meet - one for males, one for fillies. Yearlings sold, as well as those who do not meet their reserve in their trip through the ring, will be eligible.

Malibu Moon, a foundation sire for Spendthrift Farm, left a legacy behind after his death in May. Not only does the late stallion have two sons among the top 10 freshman sires in Gormley and Stanford, his son Prospective has the distinction of siring one of the top Beyer Speed Figure earners of this season.

Baby Yoda posted a Beyer of 114 in a 6 1/2-furlong allowance win Saturday at Saratoga. The 3-year-old gelding’s figure was matched by fellow 3-year-old Flightline in an allowance win the following day at Del Mar.
