Wingatui trainer Terry Kennedy found immediate success with the horse who was having her first start from his stable.
The 4yr-old worked to an early lead for rider Shankar Muniandy and extended her advantage as the race progressed.
Muniandy eventually eased the horse up at the finish as Diamond Courtz recorded an impressive maiden win by more than five lengths.
Although some winners of an 800m dash may not go on with it, Kennedy does not think yesterday’s win will be Diamond Courtz’s last.
"She can gallop; that was not just a one-off," the trainer said.
The eye-catching win came after the mare had spent more than 10 months away from the races.
Early last year, the horse was restricted to a one-start campaign for trainers John and Karen Parsons due to soreness issues.
Owner Peter Lyon spelled her before giving Kennedy a turn with the galloper.
"She ran as a 2yr-old and they rated her but she kept going lame, so Peter put her in the paddock," Kennedy said.
Because the horse went such a big race at her first start in almost a year it is unlikely Diamond Courtz will back up and race on Champions Day.
If the horse found wetter track conditions than the dead4 rated Wingatui track in her next start then Diamond Courtz could be even more competitive, Kennedy said.
The trainer also claimed race 7 when the consistent Aboli scored a deserved maiden win.
The horse is raced by Eric Parr’s Parr Bloodstock and came on a good day for the Parr family.
Parr’s brother, Lindsay, also scored success as an owner with Plowshare in race 5.
The victory came three years after Lindsay Parr purchased the horse at the Karaka yearling sales.
Parr described Plowshare as a galloper who has his share of ability but one who could be field-shy.
Rider Jillian Morris angled Plowshare wide on the track to make sure that was not a problem in the run home and the horse came with a booming finish to win.
Majic El also put in a big finish to get himself back in winning form in his first try over a middle distance in race 4.
The Claire Anderton-trained galloper had raced without luck in six runs this season without threatening to win a race.
The step up in distance to 2200m changed that yesterday as the galloper bounded away from his rating 65 rivals.
All Black Magic scored a gritty win in yesterday’s feature race for trainer Amanda Schwarz and rider Chris Johnson.
Johnson landed the horse outside leader Tomm Jones in a race totally devoid of pace before All Black Magic wore him down in the straight to win the rating 80 opening race.
All Black Magic could back up and race at Champions Day on February 3 or at Ascot Park Park on February 8.
