King Combo edged away in the stretch and earned a one-length win in a maiden claiming race on Friday at Calder Race Course to become the first winner for freshman sire Black Mambo.

Trained by Joe Calascibetta, King Combo ran 4 1/2 furlongs in :54 on a fast track.

Black Mambo stands for $5,000 at Bridlewood Farm. The Kingmambo horse out of stakes-placed winner Lassie’s Lady, by Alydar, has 73 two-year-olds in his first crop.

Black Mambo is a half brother Grade 2 winner and sire Bite the Bullet and Group 3-placed winner Love Me True, dam of multiple Group 1 winner Duke of Marmalade. Notable members of the female family include European highweight and sire Wolfhound, 2000 champion older horse Lemon Drop Kid, and 1992 Broodmare of the Year Weekend Surprise, dam of ’92 Horse of the Year and leading sire A.P. Indy and ’90 Preakness Stakes (G1) winner Summer Squall.

Black Mambo concluded his racing career in ’04 with three wins in 21 starts and $100,790 in earnings. A $1.1-million purchase by Irish bloodstock agent Demi O’Byrne at the ’00 Keeneland September yearling sale, Black Mambo finished second in the ’04 Reappeal Stakes at Calder for trainer Frank Gomez and owner William Murphy.
