Multiple G1 winner Hartnell returned to racing with a bang on 19 August, producing a brilliant performance at Caulfield to win the G2 P B Lawrence Stakes over seven furlongs.
Authorized's highest rated son was in control throughout, settled just off the early pace before taking the lead a furlong out and eased clear to win by two and a quarter lengths.
Winner of the G1 Turnbull Stakes last year and the 2015 G1 BMW, Hartnell will now head to the G1 Makybe Diva Stakes, run over a mile at Flemington on 16 September.
Hartnell is out of Debonnaire who has three winners from as many runners to her name, and hails from the family of French Champion and three-time G1 winner Suave Dancer.
Authorized is also sire of fellow G1 winners Complacent, Ambivalent and Seal Of Approval.
