Veteran stayer Caton will have to successfully lug 61kgs to make it back-to-back success in town on Wednesday for Gwenda Markwell.
The eight-year-old is nominated for the Schweppes Benchmark 67 Handicap (2400m) at Warwick Farm and will be ridden by in-form jockey Tye Angland.
Angland rode Caton to a gritty last start victory in stronger grade when carrying 56.5kgs but will have to care 4.5kgs more to repeat the result.
He will jump from barrier six on the afternoon.
Markwell also had Bolord running at the Farm and the five-year-old is also top weight at 60.5kgs.
The gelding has appreciated rain-affected tracks in recent starts but should improve in dry conditions in the TAB Rewards Benchmark 70 Handicap (1400m).
Chad Lever will take back the ride.
Lever rode Bolord to his first victory in town back in April.
Meanwhile, soon-to-be Kembla trainer Luke Price is also preparing to make the trip north with Lani Girl.
The mare finished off well to finish fourth first-up at Nowra fearlier this month before this week’s tilt at the TAB.com.au Benchmark 67 Handicap (1200m). Shoalhaven Heads trainer Terry Robinson has Andsoitiswritten in the same event.
