A quartet of winners by resident sires in Sydney and Melbourne made for a great 24 hours for Emirates Park Stud on Saturday.

Al Maher supplied a trio of winners while the stud's veteran sire Danewin had a black type winner at Rosehill in Sydney.

Al Maher 's treble was made up of Lady Mahler and Amaethon at Caulfield and King Lionheart at Rosehill.

King Lionheart, bred and sold by Emirates Park, earned a start in next Saturday's G1 Epsom Handicap was a determined victory in the Group 2 Shannon Stakes to register the first black-type success of his career.

Already a stakes placegetter, Amaethon posted his maiden black-type victory in the Listed Testa Rossa Stakes at Caulfield.

Lady Mahler, a $70,000 Magic Millions Gold Coast sale graduate, completed Al Maher's Caulfield double.

Emirates Park also bred and sold Danewin's promising son Big Time, winner of the Listed Dulcify Quality at Rosehill,

Big Time is a most pleasing product as he from the Emirates Park-owned Group winner Salameh, a homebred Secret Savings half-sister to Al Maher.

The successful run for the stud started at Canterbury on Friday night where Al Maher was represented by the unbeaten three-year-old winner Ying La.

King Lionheart and Amatheon took Al Maher's tally of stakes winner to 10 from his first three crops.

Big Time, sold at the 2010 Australian Easter Yearling Sale for $220,to prominent bloodstock agent Steve Brem, emulated his sire Danewin, who won the Dulcify Quality at the beginning of his 3YO season.

Danewin also won the G1 Spring Champion Stakes, the race Big Time may target at Randwick next Saturday.
