Comeback mare Samaready announced she was back to the big time and better than ever with a commanding victory in the Group One Moir Stakes on Friday night.

Last year's Blue Diamond winner spent a year on the sidelines with hindquarter injury but returned as a Group Three winner last month and went to another level in the Moir Stakes (1200m) when she relegated popular Queensland sprinter Buffering to yet another Group One second.

Samaready ($7) moved into the race ominously rounding the home turn and powered past front runner Buffering ($3.50 fav) early in the straight before going on to win by four lengths in heavy rain.

Trainer Mick Price had even more reason to smile as Samaready's stablemate Le Bonsir ($26) filled the minor placing, another 2-1/4 lengths away.

"We love the mare," Price said.

"It's great to see her look so well and hit the line so well.

"It was a really brave, valiant win."

Jockey Craig Newitt labelled the four-year-old a "special" horse after the victory but had a feeling a dominant performance was on the cards after trackwork earlier in the week.

"Wow," Newitt said.

"She just travelled beautifully. I just had to give her clear room and when I asked her, she exploded."

He said he knew after her work on Monday that she was "ready to explode".

"It was the best feeling she's given me in a long time," he said.

"To come away and win with that arrogance, she's something special."

A Group One win still eludes Buffering but trainer Robert Heathcote was gracious in defeat after the sprinter was placed in a Group One for the 10th time.

"I'm getting used to this feeling. That's so many Group One seconds now," Heathcote said.

"He tried his heart out but he was beaten by a better one on the day. Samaready was outstanding."

The sprinters are set for a rematch in the Manikato Stakes.
