Street Boss

Pedigree notes

Street Boss is a consistent sire of stakes winners who is capable of siring the “big horse” all breeders strive for.

Last year we suggested there would be fireworks to come and they have arrived with all the way G2 VRC Sires' winner Traffic Warden and the prodigiously talented rising star Another Wil.

Street Boss sired G1 Newmarket winner The Quarterback in his first Australian crop and it’s fair to say that if he had returned for a second successive season and sired another G1 winner he would have been “hot property”.

His stats are impressive, eight G1 winners including Champion Anamoe, 70 Stakes winners from 1,299 runners worldwide. That’s over 5.3% Stakes winners to runners from relatively modest opportunity.

On the shuttle, he has left 521 runners, 24 Stakes winners, and THREE G1 winners which is over 4.6% Stakes winners to runners off low fees. But more significantly his best horses are an elite group including not just the G1 winners Anamoe, The Quarterback and Elite Street, but also one of this season’s top juveniles G2 VRC Sires' winner Traffic Warden, G2 winning G1 Blue Diamond runner-up Hanseatic, Arcaded (2nd Blue Diamond Prelude), Pericles (2nd Rosehill Guineas), as well as his rising star Another Wil.

That’s a wonderful rate of elite production off a low fee and with an interrupted career. The next Anamoe could well be in the pipeline.

G1 Statistics

Street Boss has three Australian sired G1 winners who are out of mares by Australia’s three leading broodmare sires: Redoute’s Choice, Encosta de Lago and Exceed And Excel. These are all Northern Dancer lines, two being Danehill/Danzig line and it is worth mentioning that emerging talent Another Wil is also out of a Danzig line mare who carries two lines of Northern Dancer.

Overall, he has EIGHT G1 winners, all out of mares by different broodmare sires indicating his versatility.

• 5/8 G1 winners have a return of Mr Prospector in the mare
• 2/8 G1 winners plus G1 2nd Hanseatic have a return of Danehill in the mare.

Best Nicks
Street Boss has the most Australian Stakes winners out of mares by Exceed And Excel and Lonhro. 
His best percentages of Stakes winners to runners with 10 named foals or more are with mares by Lonhro, Testa Rossa, Exceed And Excel, Fastnet Rock, Danehill Dancer and Encosta de Lago among sires whose daughters can easily be found in Australia. They all have at least 10% Stakes winners to runners with Street Boss as sire.
Street Boss definitely has a nick with Exceed And Excel, the cross has 10% Stakes winners to runners including G1 winner Elite Street and Gr1 Blue Diamond runnerup Hanseatic.
Street Boss has a very strong nick with returns of his own great grandsire Mr Prospector. An astounding 75% of his Stakes winners have a return of Mr Prospector in the mare including five of his eight G1 winners.

Inbreeding / Linebreeding options
The most obvious candidate for inbreeding to the pedigree of Street Boss is the mare Helen Street who is the dam of Street Cry. Helen Street is proving to be an influential mare, the results of inbreeding to her include include the multiple G1 winner Victor Ludorum, G2 winner and G1-placed Lucida, G3 winner Shocking Luck, G1 Victoria Derby runner-up Southern Moon, the talented Stakes-placed Spirit Of Gaylard and first two starts Caulfield Saturday winner, rising star Cute As, who is by Thronum out of a Street Cry mare.

These early results are encouraging, this is a pattern worth repeating and can be achieved using mares by Shamardal or his sons which include Lope de Vega, Puissance de Lune, Gingerbread Man and Crackerjack King. Or daughters of G1-placed Thronum who is by Snitzel out of a daughter of Helen Street.

Strategy One
Send mares by Exceed And Excel or with him in the pedigree as this is the best nick for Street Boss. Mares by other sons of Danehill such as Redoute’s Choice, Fastnet Rock or Danehill Dancer and his son Choisir would be another worthwhile part of this strategy.

Strategy Two
Inbreeding to Helen Street the dam of Street Boss’ sire can be achieved using mares by Shamardal and sons, or Lope de Vega and sons, or Thronum. The desired effect can occur with those sires anywhere in the mare’s pedigree.

Strategy Three
Returning Mr Prospector has been highly effective for Street Boss. A quick way to find stallions with a presence of Mr Prospector in their makeup is to refer to the five-generation index at the back of STALLIONS 2023 and 2024. There is also a quick ancestor search on the home page of stallions.com.au.

Strategy Four
Street Boss and his sire Street Cry have both had considerable success with returns of the great sires Zabeel and Seattle Slew in the mare. Sources of Zabeel are readily available via Lonhro and sons. Sources of Seattle Slew are harder to find but include Better Than Ready, Rebel Dane, Super One and Justify whose oldest daughters are just turning three.
