Mulaazem, a Group Two winning half brother to Sepoy, has been retired to Emirates Park Stud.

The three-year-old suffered an injury during the Hobartville Stakes earlier this month and he will go to Emirates' Digger's Rest property in Victoria.

Trainer by Peter Moody for the owner of Emirates Park, Dubai's Nasser Lootah, Mulaazem won three of his seven starts, the highlight being his all-the-way triumph in the Group Two Autumn Stakes in February.

The Victoria Derby quinella of Fiveandahalfstar and Super Cool filled the placings and reinforced the form on Saturday when Super Cool beat Fiveandahalfstar in the Australian Cup.

An Emirates Park statement said although the timing of his stud career had been determined earlier than expected, stallion duties had always been at the forefront of the colt's future plans as a Group Two winning half-brother to a multiple champion sprinter and member of the Mr Prospector sire line.

Sepoy, the champion two-year-old of the 2010/11 season, was rated the world's best three-year-old sprinter the following year.

He began stud duties for Darley last season.

"This current crop of three-year-olds is outstanding at all levels, possibly the best seen for a decade, and we were very much looking forward to campaigning him through the autumn and beyond following his brilliant victory over Fiveandahalfstar and Super Cool," Emirates Park chief executive Trevor Lobb said.

"The injury has brought a premature end to his exciting racing career and everyone involved is very disappointed."

Mulaazem will stand his first season for $7700 (inc GST).
