The addition of Cowtown Cat to Ohio’s stallion roster near the end of 2014 automatically put him at the top of the state’s general sire list by progeny earnings, and he stands a strong chance of remaining in that spot until he can defend the title with his own Ohio-sired runners in 2018.

Cowtown Cat, an 11-year-old son of Distorted Humor, will make his Buckeye State debut in 2015 at Mapleton Thoroughbred Farm in Polk, Ohio, for an advertised fee of $2,500. He previously had stood his entire career at Journeyman Stud in Florida, where he retired for the 2009 breeding season.

The performance of a stallion’s progeny on the racetrack is ultimately the biggest testament to that horse’s success or failure at stud. However, the truly transcendent stallions leave pieces of their legacy through the generations as sires of sires.

One only needs to look at the myriad sons of all-time greats Mr. Prospector, Northern Dancer, and Storm Cat that were successful at stud to verify the trio’s status that they helped shape the breed.

Grade 2 winner My Best Brother has been retired from racing and will stand the 2015 breeding season at Stonewall’s Prestige Stallions in Ocala, Fla.

In the 30 years from 1955 through 1984, either Nasrullah or one of his male-line descendants led the American general sire list 18 times. However, in the 30 years since Seattle Slew led the list for the only time in 1984, only two Nasrullah-line horses have led the same list.

Those two are the great A.P. Indy and his grandson, Tapit, who climbed to the top of the list in 2014. After a gap of 20 years dominated by Northern Dancer and Mr. Prospector, the male line of A.P. Indy has scored three championships in the past 12 years.

Law Enforcement, a multiple stakes-winning son of Posse, has been purchased by David O. Hansen’s Quintana Farm, and will remain standing at Dove Hill Farm in New Prague, Minn., for the 2015 breeding season.
