New York-bred Disco Partner had his brightest performances on the racetrack in his home state, and, fittingly, retires to stud there for 2020. A millionaire and North American track-record setter, Disco Partner will begin a stallion career at Rockridge Stud in Hudson, N.Y., in 2020. He keys a strong incoming hand for the farm, which also welcomes Grade 1 winner Leofric to the roster.

Disco Partner, a 7-year-old son of the late Disco Rico, raced as a homebred for Patricia Generazio and retired with a career record of 33-11-6-8 for earnings of more than $1.4 million.

Force the Pass will enter stud in Maryland in 2020, becoming a rare Grade 1 winner to stand in the state. He is the latest newcomer at Louis and Grace Merryman’s Anchor and Hope Farm in Port Deposit, Md., which is continuing to build an exciting roster of young stallions even while rebuilding from a destructive barn fire in August.

It’s college basketball season, and everything in Lexington, Ky., is wallpapered in Wildcat blue. But students from the University of Kentucky could be forgiven for having fond thoughts about an adopted Oklahoma Sooner. Multiple Grade 3 winner Fear the Cowboy, bred and raised by the University of Kentucky’s Maine Chance Farm, which employs students as part of the curriculum, enters stud this season at Glasses Creek Ranch near Madill, Okla.

At age 25, Tale of the Cat has shown no signs of slowing down. Over the last decade, the Coolmore stallion is responsible for multiple Eclipse Award champion Gio Ponti and Breeders’ Cup Distaff winner Stopchargingmaria, and in 2019 continued to light the board with several stakes-performing juveniles who will eye bigger things.

Journeyman Stud has found great success this year with freshman sire Khozan, a lightly raced half-brother to a champion. The Ocala, Fla., farm hopes to continue that winning formula as it adds St Patrick’s Day to its roster for 2020.

St Patrick’s Day is a Group 3-placed full brother to Triple Crown winner and leading freshman sire American Pharoah. He will stand as the property of a syndicate that includes Journeyman, Climax Stallions, and Stonehedge Farm.

Dixieland Band, one of the original three stallions at Lane’s End Farm, died at age 30 in 2010. A decade later, his great-grandson Catalina Cruiser will enter stud at the farm for the 2020 season as Lane’s End continues to invest in this sire line.

His name was Halo, with all that it implies. But the nearly black stallion was anything but angelic. As a yearling, he objected so strenuously to the scenario in the walking ring that he flipped outside the sale pavilion. During his racing career, he would eject his exercise rider and take solo turns around the training track in Aiken, S.C., and occasionally take unscheduled trips to romance the fillies at neighboring barns. As a stallion, he had a reputation for being aggressive and territorial, and required a muzzle to be handled.

Over its storied history since being founded in 1937 by Leslie Combs II – who named the property after the 1879 Belmont Stakes winner bred by his great-grandfather – Spendthrift Farm has been an industry leader as a stallion operation. The farm syndicated back-to-back Triple Crown winners Seattle Slew and Affirmed in the 1970s and also has been home to such standouts as Raise a Native, Nashua, Swaps, Gallant Man, Foolish Pleasure, Majestic Prince, and more.

Uncle Mo shattered records as he led the freshman sire list in 2015, and is now reaping some of the results of that early success. Uncle Mo's current juveniles are those conceived in spring 2016 following the success of his first runners, and he has ridden that wave to a solid third on the North American juvenile sire list, illustrated when his daughters Bast and Donna Veloce swept the exacta in the Grade 1 Starlet Stakes on Saturday at Los Alamitos.

Unaided, the dam of Breeders' Cup Mile winner Uni, was purchased by Peter Brant's White Birch Farm for $1,382,661 in U.S. funds over the weekend at the Arqana December breeding stock sale in France.

British-born Unaided, a 10-year-old Dansili mare, was unplaced in eight starts while racing for Japanese connections. She was shipped to the U.S. to be bred to internationally-successful sire More Than Ready, then sold for $230,000 at the 2013 Keeneland November breeding stock sale. Her resulting first foal, Uni, was born in Great Britain for Haras D'Etreham.
