Might And Power resumed in the Show County Quality, over 1,200 metres (6 furlongs) and came from near the tail of the field to defeat the Caulfield Guineas winner Alfa and the stakeswinning sprinter Armidale.
After such an emphatic win, betting markets for the Cox Plate and the Melbourne Cup were hastily rearranged, with Might and Power being installed as a short-priced favourite for both events.
His trainer, Jack Denham, who had Filante set for the Cox Plate, elected to bypass the Valley feature with Might And Power and go into the Melbourne Cup without another run.
At Flemington, Might And Power was to carry 56 kilograms (8 st 11 lb) having received a penalty of three-and-a-half kilos (a modern record) for his win in the Caulfield Cup.
Starting favourite, he led, and withstood three distinct waves of challenges – Crying Game at the 1,600-metre point, Linesman on the home turn, and Doriemus over the final 200 metres.
Back in Sydney, Might And Power ran second to the Australian Guineas winner Gold Guru in the Ranvet Stakes, but connections were unhappy with Jim Cassidy's ride, and Brian York again took over.
Back to full fitness, and well-rated by York, Might And Power recorded fast time and defeated Gold Guru and Doriemus by five lengths in the Mercedes Classic.
At Randwick, three weeks later, Might and Power faced a field of six in the AJC Queen Elizabeth Stakes, which included the multiple Group One winners Juggler, Champagne, Catalan Opening, and Intergaze, but it was a one-act affair as he won by 10+1⁄2 lengths.
Shane Dye led on the multiple Group One winner Tycoon Lil, but Cassidy bided his time on Might And Power, in second place, and surged to the front over the closing stages to win by just over two lengths.
Owner Nick Moraitis was invited to run Might And Power in the Japan Cup but was unable to secure a direct flight, and elected to send the horse for a spell.
