Effinex, a Grade 1 winner and young New York stallion, died Wednesday in his stall of a pulmonary aneurysm at McMahon of Saratoga Thoroughbreds in Saratoga Springs, N.Y. He was 7.
The son of Mineshaft had recently relocated to McMahon of Saratoga after standing his first season at Questroyal North in Stillwater, N.Y. this spring for an advertised fee of $10,000.
Effinex raced as a homebred for Dr. Russell Cohen of Tri-Bone Stables, and he was trained by Jimmy Jerkens.
"I got a call last night at 10 o'clock that he was dead," Cohen said. "The groom left the barn after feeding him at seven, the secretary’s office is right in the stallion barn and she left at 7:30, and one of the veterinarians from Rood and Riddle lives above the stallion barn. He heard a big noise, he went downstairs to find out what it was, and the horse was dead. Rood and Riddle did a postmortem on him and his lungs and trachea were full of blood. He had a pulmonary aneurysm."
Effinex won nine of 28 starts during his on-track career for earnings of $3,312,950.
The New York-bred's biggest wins came in the Grade 1 Clark Handicap, two editions of the Grade 2 Suburban Handicap, the Grade 2 Oaklawn Handicap, the Grade 3 Excelsior Stakes, and the non-graded Empire Classic Handicap. He finished second to American Pharoah in the 2015 Breeders' Cup Classic at Keeneland, and was also in the money in two runnings of the Grade 1 Jockey Club Gold Cup.
