Early in his career in 1960s
New York City, Frankel assisted the prominent trainer
Buddy Jacobson. On his own, Frankel saddled his first winner late in 1966 before struggling somewhat in 1967, when he won with just 9 of 101 starters. During 1968 however, he won 36 of 165 outings with his horses accumulating $167,000 in
purse money. In the next few years, he continued to prosper in New York and during the winter of 1970–71, he enjoyed some success at the West Coast meeting at
Santa Anita. After moving permanently to California in 1972, Frankel scored a series of wins that brought him to the attention of the horse-betting world, winning a record 60 races at
Hollywood Park. Many of those victories came with runners he acquired as low-cost claimers for one of his owners like
Edmund Gann, with whom he had a 30-year working relationship. These horses typically showed dramatic improvement under his care, sometimes winning their next start against higher-priced claiming levels. Frankel was an avid follower of the training techniques of
Charlie Whittingham, trainer of champions such as
Ferdinand and
Sunday Silence. Frankel won several
Eclipse Awards, the year-end thoroughbred racing awards, for best trainer. He set earnings records, Grade I stakes victory records, and many others. Frankel also won the
Pacific Classic Stakes a record six times, including four times in a row, also a record. Some of his best race horses include:
Squirtle Squirt, his first
Breeders' Cup winner;
Skimming, two-time winner of the Grade 1
Pacific Classic Stakes;
Sightseek, winner of the
Humana Distaff Handicap (Gr. I) and
Ogden Phipps Handicap (Gr. I); triple Grade I winner
Empire Maker, winner of the
Belmont Stakes (Gr. I); multiple Grade I winning
Peace Rules; two-time
Santa Anita Handicap (Gr. I) winner
Milwaukee Brew;
Breeders' Cup Filly & Mare Turf (Gr. I) winner
Starine, whom he also owned; and
Ghostzapper, the
Breeders' Cup Classic (Gr. I) winner who was voted the 2004
Eclipse Award for Horse of the Year. Frankel was the
U.S. Champion Trainer by earnings in 2002 and 2003. On June 26, 2005,
Wild Desert, owned by several businesspeople including former
New York Yankees manager
Joe Torre, gave Frankel his first victory in the $1 million
Queen's Plate, the first leg of the
Canadian Triple Crown at
Woodbine Racetrack. ==Personal life and death==
