Group One winning sprinter Snitzerland has been retired from racing and has a possible date with Black Caviar's half brother All Too Hard in the spring.

The four-year-old was pulled up in an exercise gallop on the eve of the BTC Cup in April. Although cleared of serious injury, she suffered ligament damage which meant a lengthy spell.

Her owners Neil Werrett and Steve McCann decided on Sunday to send her to the breeding barn this spring.

Werrett, a part-owner of Black Caviar, is also a shareholder in Vinery Stud where All Too Hard stands.

Snitzerland's highlight in a career of many stellar performances was her win in the Group One Lightning Stakes at Flemington in February.

The mare's trainer Gerald Ryan earmarked her as a Group One performer from the day she came to his Rosehill stable.

"She was a good two-year-old, a good three-year-old and a good four-year-old," Ryan said.

"She raced at the top level in Sydney and Melbourne for three seasons.

"I will miss her. She has taken up a lot of my time over the last 2-1/2 years and has been a great mare."

"From the first day she galloped I knew how good she was.

Others realised how good she was when they watched as champion colt Pierro had to fight to run her down in the 2012 Golden Slipper.

Last spring she suffered a respiratory ailment but made a late carnival appearance at Flemington where she was nosed out of victory by Lankan Rupee in a Listed sprint at Flemington.

Lankan Rupee has gone on to win three Group One races and is now the world's highest ranked sprinter.

Ryan is also a breeding buff and says All Too Hard is the logical stallion for Snitzerland.

Snitzerland goes to stud with eight wins from 20 starts and prize money of almost $2 million.
