Comignaghi did not give her rivals a look in when controlling the pace in front with the John and Karen Parsons-trained 7yr-old, who won the group 3, 1600m feature by two and a-half lengths.
The victory meant the Argentinian born rider completed a fine Champions Day hat-trick after she rode Sitarist to win the listed Dunedin Gold Cup and El Gladiador to win the Dunedin Guineas.
About two years ago, following a frustrating run of injuries,
Comignaghi had considered quitting riding. However Karen Parsons did not want Comignaghi’s talent to go to waste, so she talked her out of the idea.
Comignaghi repaid the Parsons’ faith in her with three faultless rides in Saturday’s stakes races.
"We’re thrilled for Tina, who rode really well in all of those black-type wins," Parsons said.
"She did such a great job for us today."
Comignaghi won her first two listed races aboard Courte Zarindi in fillies races two seasons ago.
"Getting a listed [win] was a big goal. Getting more than one in a day is a dream come true."
Comignaghi turned the White Robe Lodge Weight For Age into a one-horse affair as she urged the 7yr-old to the front early in the 1600m race. Killarney got into such a comfortable rhythm in the lead that nothing was going to catch him.
"He likes going at his own pace in front, so I let him do that from his wide gate,’’ the jockey said.
"We always knew he had the ability, it’s just [a matter of] getting things right with him.
"He could have gone around again."
Killarney pulled away from runner-up Shirley Maude in the home straight to win by two and a-half lengths.
Belle Fascino ran in to third, a further neck away.
The favourite, Who Dares Wins, received an economical run and disappointed in battling to seventh.
Comignaghi used contrasting tactics to win the listed Dunedin Gold Cup aboard Sitarist.
The Road To Rock mare got in the deciding stride to nail West Otago up-and-comer Mr Intelligence on the line in a thrilling finish to the 2400m listed feature.
Comignaghi admitted she did not have high hopes when Sitarist was stuck in traffic before the home turn.
"I thought she was gone, but maybe I would get second, but she fought really hard."
Parsons revealed that Sitarist was lucky to to have made the race.
"She’d been battling a foot infection, and it was only on Thursday that the blacksmith gave her the green light to run."
Mr Intelligence was a nose away from Sitarist on the line in an impressive effort in the toughest test of his short career.
Riviera Rock went a big race in finishing third, a further two and a quarter-lengths away. The Graham and Michael Eade-trained galloper was slow to begin, which forced rider Leah Hemi to loop the field in search of the lead.
