Fresh from siring a Group II double at Randwick on Saturday with fast juveniles Tempted and Tentyris, Street Boss (USA) kept the ball rolling with another stakes-winner on Monday at Morphettville when four year-old mare Elphinstone landed the Listed SAJC Colin Hayes Memorial Cup (1600m).

There were five heats for juveniles at Randwick on Monday morning with Golden Slipper contenders West of Swindon and Bellazaine both in action, plus some well bred unraced heat winners including the brother to G1 winner Captivant and the Farnan first foal of Champion NZ 3YO Filly Jennifer Eccles.
