Trainer Peter Moody said all week that Black Caviar was in career best form, and she proved just that in her returning to racing, easily winning the Group 1 Lightning Stakes on Saturday and setting a new course record.

In her first race since a narrow victory at Royal Ascot in June 2012, Black Caviar put rest any rumours that she's lost her form, easily accounting for her rivals in the 1000 metre straight race that is now named after her.

The 6 year old mare is now 23 wins from 23 starts, and has earnt a massive $7 million in career prize money.

She comfortably held off stablemates Moment of Change and Golden Archer, who gave Peter Moody a pleasing trifecta.

"It's a little bit emotional for the first time", Moody said after the race.

"Shit it's good to have her back".

Jockey Luke Nolan, who nearly lost in Ascot after easing the super-mare down too far from the finish, took no chances in the comeback race.

"I just gave her a squeeze because I didn't want her getting too complacent and I got too much of a kick in the ass for it at Ascot, so I just shook the reigns out a bit today and made sure she ran through to the line".

It was Black Caviar's 13th Group 1 win, putting her only 1 behind Kingston Town, and on par with turf legends Sunline and Tie The Knot. Her new track record of 55.42 erases a record held by Special which has stood for 25 years.
