Ferguson steered home four winners, including the Wyndham Cup winner, The Wrath Of Robyn, from seven drives at Young Quinn Raceway.
Christian Grey started Ferguson's run, winning race 2 for Ferguson's employer, Wayne Adams, before Ferguson rekindled his partnership with My Guy Mac, recording his fourth win with the Ross Wilson trained 4yr old.
Ferguson capped off the day when he guided home Rory to win the last on the card. His previous best tally for a meeting was three, recorded at Forbury Park in June.
The Wrath Of Robyn has not always been the safest away from a standing start, but his manners were impeccable on Saturday as Ferguson went straight to the lead and was never headed on the Washington VC 5yr old.
Backup was a brave second after facing the breeze for most of the 3200m.
Backup's stablemate Waikiki Beach debuted in style, winning the group 3 Kindergarten Stakes by 2 lengths over fellow All Stars runner Motu Premier in 1.58.9 on an easy track.
