Ad Valorem lost a great opportunity to win Australia’s first-season sires’ premiership when his colt Free Wheeling reared at the start of the $252,000 Queensland Sires’ Produce Stakes in June.

Eliza Park sire Written Tycoon ($644,000) will win the freshman title from Ad Valorem ($552,000) but the Darley sire can top the winners’ table after Boston Tea scored on debut at Bathurst on Monday.

Ad Valorem joined his Darley associate Nadeem, All Bar One and Red Dazzler on 8 winners with six days remaining before season’s end.

Boston Tea (2g Ad Valorem – Provokes by Octagonal) is a Darley homebred and he won the Don Ryan Hcp (1200m) by a long head from Jabel (Dubai Destination).

Boston Tea is from Woodlands mare Provokes who won three races in Sydney and was also stakes placed in the G3 AJC Sapphire Stakes and LR Dark Jewel Classic at Scone.

Second dam Excited Angel (Don’t Say Halo) was a G2 winner of the VRC Bloodhorse Breeders’ Plate and G3 MVRC Diamond Jubilee Stakes.
