MARY Slack has yet another good broodmare prospect for Wilgerbosdrift Stud in Headstrong. The five-year-old mare by Pivotal produced a powerful finish under a confident Anthony Delpech to collar Herman Brown’s runner Norbury a stride short of the line in a 1400m Handicap sponsored by Brown himself at Scottsville on Wednesday, 11 August.

Headstrong is a good racing prospect for the new season too. With the turn of foot she showed over the last 200m, and lightly raced to boot, she can be watched in forthcoming fillies features.
