At the Threshold, Sire of Derby Winner Lil E. Tee, Dead

At the Threshold, whose son Lil E. Tee won the 1992 Kentucky Derby (gr. I) for W. Cal Partee, died March 23 of an apparent stroke at Purdue University School of Veterinary Medicine in West Lafayette, Ind. The 21-year-old stallion stood at Wayne Houston's Stoney Creek Horse Farm near Mooreland, Ind.

Partee purchased At the Threshold for $150,000 in November of the horse's 2-year-old season in 1983. Bred by Raymond Karlinsky and Arthur Levien, At the Threshold was a two-time grade I winner at three and ran third in the Kentucky Derby. His grade I wins came at Arlington, where he captured the Arlington Classic and American Derby (in a deadheat). He also won that year's Ohio Derby (gr. II) and Jim Beam Stakes (gr. III), and was retired with nine wins from 18 starts and earnings of $695,930.

At the Threshold (Norcliffe--Winver, by Vertex) entered stud for a syndicate at John Franks and John Fernung's Southland Farm near Ocala, Fla. He later stood at farms in Kentucky, Arkansas, Oklahoma, Texas, and Iowa before being moved to Stoney Creek for this year's breeding season. Lil E. Tee was retired with millionaire status and stands at Jim Plemmons' Old Frakfort Stud near Lexington.

At the Threshold has sired eight stakes winners and the earners of $10 million.
