South Australian Derby 2021

Saturday May 8, 2021

Ladbrokes Tip: Locally trained 3YOs have the best record in the SA Derby

The South Australian Derby is a Group 1 race for three-year-old staying types held at Morphettville Racecourse in mid-May during the Adelaide Autumn Racing Carnival. Contested a week after the Group 1 Schweppes Australasian Oaks (2000m) for the fillies, the set weights clash takes place over 2500m and offers $500,000 in prize money. For 2020 the SA Derby prize money was cut to $400,000 due to the global Coronavirus crisis.

It is one of the major Morphettville races during the season and locally-trained horses have a top record in the event.

The latest edition of the South Australian Derby took place on Saturday May 8, 2021 and was won by the ATC Derby champion Explosive Jack.

South Australian Derby Odds

South Australian Derby odds are usually led by the best performing three-year-olds coming off 2000m runs at the track in either the Chairman’s Stakes or the Schweppes Oaks.

Favourites tend to have an outstanding recent record in the race with nine winning 2006 – 2021. The latest favourites in SA Derby betting to salute were: Explosive Jack ($4 in 2021), Russian Camelot ($2.90 in 2020), Leicester ($4 in 2018) and the odds-on top elect Delicacy ($1.90 2015).

Previous experience at Morphettville often helps determine the South Australian Derby betting markets, as do those tested in previous Group 1 races either in Adelaide or interstate like the Group 1 Australian Derby (2400m) in Sydney the month before. Explosive Jack (2021) was the last horse to do the ATC Derby – SA Derby double.

South Australian Derby Form Guide

The South Australian Derby form guide provides all the must know information before punters place a bet including the jockeys, trainers, barriers and lead-up form of the three-year-olds in the mix.

Wide barriers are not something to shy away from with plenty of good horses getting the job done from barrier 10 or wider including Explosive Jack (10 of 16 in 2021), Volatile Mix (barrier 11 in 2017), Kidnapped who saluted from the outside barrier 16 of 16 in 2010, as did both Tails Of Triomphe (2005) and Testafiable (2006).

Over the years the South Australian Derby form has stacked up in better staying races in Melbourne during the spring including in 2003 when Mummify won the SA Derby – Caulfield Cup double before running third in the following year’s Sydney Cup and the 2005 Caulfield Cup.

Count Chivas (1995) and Shivas Revenge (1991) both won the SA Derby before placing second in the iconic Melbourne Cup in their respective years, while Subzero (1992) completed the double winning that spring’s ‘race that stops a nation’.

More recently the 2020 SA Derby champion Russian Camelot went on to run top three in his next four Group 1 starts in Melbourne including winning the Underwood Stakes and finishing third in the Cox Plate to Sir Dragonet that spring.

South Australian Derby Tips

The favourites have a strong record in the race so taking the top fancy in betting is a good South Australian Derby tip.

Fillies have only won three times since 1999, so taking the colts and geldings that are high up the markets coming out of a run in the Chairman’s Stakes in Adelaide is a great SA Derby betting tip.

  • To Win: #1 Explosive Jack ($3.50 at time of publish) 

Sticking with the Group 1 winner last time out in Sydney, Ciaron Maher & David Eustace’s Explosive Jack, who is going from strength to strength this campaign. He’s at much shorter odds here, but is proven at the distance (or close to) and has plenty of class. Only a narrow win in the ATC Derby, but he beat some nice types and barrier 10 here with John Allen aboard suits.
