ABOUT THE NAME M375
M375 is a tribute to Murphy's favorite horse, the 1977 Triple Crown winner Seattle Slew.
While attending the University of Florida, Murphy majored in computer science and created a handicapping program. These were the days before personal computers and when programs were printed on cards and yards of data were produced from a printer that took up a whole room. Murphy named his program after his hero, but the machine insisted on printing ‘SLEW’ upside down, which reads "M375." (See the animation in the header of this website.)
​
As Murphy developed his extensive pedigree program, his breeding and racing business became M375 Thoroughbreds, Inc.
M375 OVER THE YEARS
Since making its first purchases in the 1980s, M375 partnerships have bought or bred 35 horses with impressive results that far exceed industry averages (data through Nov. 2024):
Of these horses, 13 were homebreds, including the stakes-winning filly Platinum Tiara, who finished a close-up second in the 2000 Breeders' Cup Juvenile Fillies.
Golden Spikes was a 2006 Keeneland September yearling purchase who went on to be a Graded stakes winner at age three.
​
Other notable runners include Strike Three, Astra Ridge, Diamond Studs, Swing and Miss, Z. Flash Gun, Compuquine, and Artillerist.
​
Whether through well-thought-out mating plans or by selecting horses out of a sales catalog, M375 uses its proprietary computerized data, along with physical analysis, to efficiently identify Thoroughbreds that will become successful racehorses and M375 "approved” producers.
