He won consecutive stakes at six furlongs in August and September, a minor stakes at 1 1/8 miles on April 4, and the Group 3 Chairman’s Stakes at 1 1/4 miles on April 25. Saturday, Dalasan starts in the longest race of his career, the Group 1 South Australian Derby at 1 9/16 miles for Southern Hemisphere 3-year-olds at Morphettville Racecourse in Adelaide. As of Wednesday, Dalasan was the 2-1 favorite in future-book betting against 13 rivals in the $257,200 race.

In his two stakes wins in April, Dalasan closed with interest, particularly when he rallied from sixth to win the Group 3 Chairman’s Stakes on April 25 at Morphettville as the 1-2 favorite. Trained by Leon Macdonald and his son-in-law Andrew Gluyas, Dalasan has won 7 of 14 starts. He was fifth in the $3.26 million All-Star Mile against older horses at Caulfield in March.
