Hammond combined with two Echuca trainers to score during Saturday’s meeting.
The talented hoop produced a copybook ride to guide favourite Got Out The Fence to victory in the J & M Chaser Bins Maiden Plate (1100m).
Trained by Hammond’s boss Gwenda Johnstone, Got Out The Fence justified his $3 favouritism with a dominant two-and-a-quarter-length success.
Got Out The Fence is a four-year-old by All American out of the mare Echuca Jewels, who was trained by Johnstone.
Hammond steered Got Out The Fence to a one-out one-back spot from barrier five and after hitting the front early in the straight, raced away to beat Xtravagant Fire ($15) and Viking Rebel ($4).
The double arrived in the final race.
Hammond combined with trainer Tayne Foster and bonny mare Enamour in the Chicken Supreme Kerang Benchmark 58 Handicap (1400m).
From the inside gate, Hammond was positive aboard the six-year-old, taking her straight to the front — and that is where Enamour stayed.
Backed from $11 into $7, Enamour packed too much punch over the concluding stages, beating home Aoife ($5) by a length, with Sanctimonious a further head away in third.
It was nearly a treble, with Hammond narrowly edged out aboard Echuca galloper Live Life Loud in the Bet365 Maiden Plate (1400m).
The John Thomas-trained Live Life Loud ($12) came with a strong run from midfield, but was lipped out by Saltation, ridden by comeback jockey Stephen Brown Jr.
Hammond now has seven career winners and it was the second double of her career after a now famous brace on Echuca Cup Day.
Hammond and Johnstone travelled to Stawell on Sunday with evergreen sprinter Pravro, who ran a game second to hot favourite Zion in the SM & LJ Reading Transport Benchmark 70 Handicap (1100m).
