McCoull has won the feature race for two year olds for the past five years in a row and his overall record is nine wins in the past 20 years.

Few jockeys anywhere could boast such dominance of a single event.

His winners have been Vetyvere (1997), Our Missouri (1998), Rory Mor (2008), Capone (2009), Western Hero (2012), Inner Warrior (2013), Admiral (2014), Siorca (2015) and Hard Empire (2016).

Four of those horses have been trained by Barry Campbell who will supply McCoull’s mount again this year in the lightly-raced Hinchinbrook gelding Pennstock.

So far Pennstock doesn’t have much race form to recommend him, finishing a well beaten ninth in Hobart a fortnight ago at his only start.

However his breeding alone suggests he might be an improver.

He is out of the Hennessy mare Penn, a half sister to group 1 winner Alfa.

Penn is the dam of seven winners including the promising Treasury Bond.

Smart filly Gee Gee Lanett is an odds-on favourite in early betting and could give owners Paul and Elizabeth Geard their first win in the race.

The Stuart Gandy-trained youngster has won four of her past five starts and is drawn to get a good run from barrier 1.

Trainer Scott Brunton will be chasing his third consecutive win in another of Sunday’s feature races, the $30,000 Tasmanian St Leger.

He scored in 2015 with Rose Of Innocence and again last year with Demons Run, while his father David won in 2006 with Seranita.

Demons Run is one of three stable runners this year and the likely favourite.

Class mare Geegees Goldengirl is topweight and will be trying to emulate her illustrious half-brother Geegees Blackflash who won the St Leger in 2014.

Brunton also has strong chances in two other $30,000 races.

Angel Of The Abyss shares early favouritism with Chillout in the 3YO Classic and Step The Pedal is favourite for the Open Handicap.

Step The Pedal is the highest-rated horse in the field but under the set weights and penalties conditions she has only 0.5 kilograms over the minimum.

In contrast, Blaze Forth is the second lowest-rated runner but has to carry 58kg because he’s won a race worth $20,000 or more to the winner.

Blaze Forth’s trainer John Blacker believes the conditions are unfair and should be changed.

Tasracing has said it will review them if other trainers agree.
