Williams' shortest-priced ride of the day comes up in the first race, the $150,000 Next Generation Sprinters Series Final (1200m), in which he rides Stars Of Dom.
It will be his first ride on the Lindsay Park-trained daughter of Exceedance, who has metro seconds to her name from her only two starts to date, and Williams was buoyed by a trackwork report from fellow rider Blake Shinn.
"Blake actually worked her on Monday or Tuesday and said that she's going really well," Williams said of the $2 favourite.
"She's had two starts, really good form references and been beaten by nice horses when she was beaten both times."
Williams' other favourite is Losesomewinmore, who he will reunite with for the first time since partnering the Richard and Chantelle Jolly-trained gelding to victory in July last year.
"He's won five times down the straight, so he's a great straight horse," Williams said.
"If he produces the acceleration that he did two starts ago they'll have to beat him and, his run the other day, they felt there were excuses for him the way the track conditions were."
