The four heat winners were: Ringbark Road, Spring Rock, Spring Cedar and Spring Rowan.
Peter Sullivan's Identity Thief was the lone non-Byers winner of the five heats.
At 73 years of age and still training at a high level, Pauline was chuffed to grab four of the heats last week and was surprised with just how prolific a day the team had.
“Four out of five, it was great,” the veteran trainer said.
“We thought Ringbark Road would win and Spring Rock, as that was his first run back for a while and he was jumping out of his skin.
“We thought Spring Rowan would have had some chance but we did not expect we would win four. We were real pleased.”
Rowan and Cedar are from the same Fernando Bale and Spring Fair litter.
Ringbark Road and Storm are litter mates out of a Fernando Bale and Cardwell litter.
Spring Rock posted the fastest time of the four - 16.97 seconds – over the speedy sprint trip.
The red brindle dog is a 39-time career winner and claimed the Ipswich Sprint Final over 431 metres late last year.
