Oxbow’s May 18 Preakness Stakes win was the first classic win for his breeder, Richard Santulli. It also was a welcome payoff for Santulli’s 10-year investment in the broodmare Tizamazing, a $1 million yearling who never made it to the races.

Grade 1 winner Zensational had his first winner on the track with the first-time starter Sensational Nikki at Hollywood Park on Sunday.

Sensational Nikki ran five furlongs in 1:00.19, winning by three-quarters of a length over Wired for Fun in a six-runner race for 2-year-old maiden fillies. Trained by Peter Miller for Rockingham Ranch, Sensational Nikki was purchased for $75,000 at the Barretts March sale of selected 2-year-olds in-training earlier this year.

I’ll Raise You One, a pensioned Ohio stallion and Grade 3-placed winner, was euthanized due to the infirmities of old age at Fair Winds Farm in Waynesville, Ohio. He was 29 years old.

Bred in Kentucky by Three Chimneys Farm Venture II, the son of Far North was bought by owner Al Corrado for $16,000 at the 1985 Keeneland September yearling sale. After his first start, trainer James Morgan described I’ll Raise You One as “the fastest horse I ever trained.”

This year’s Preakness Stakes brought a sense of déjà vu to horse-racing fans when they witnessed the Hall of Fame trainer-jockey combination of D. Wayne Lukas and Gary Stevens return to the winner’s circle in a classic.

Lukas and Stevens first teamed up for classic glory in the 1988 Kentucky Derby with the late, great filly Winning Colors. After an estrangement during the early 1990s, they joined forces again in 1995 with a Michael Tabor-owned colt who would fly under the radar in the week leading up to the Kentucky Derby.

Grade 1 winner and sire Unaccounted For died Wednesday in Turkey after suffering from ethmoid hematoma, an upper respiratory tract anomaly found in horses. The son of Private Account, who had stood abroad since 2002, was 22.

Unaccounted For, trained by Scotty Schulhofer, enjoyed his best season as a 4-year-old in 1995, winning the Grade 1 Whitney Handicap, finishing second to champion Cigar in the Grade 1 Jockey Club Gold Cup, and running third behind that rival in the Breeders' Cup Classic.
