Underwood Stakes Tips

Underwood Stakes betting tips are usually headed by the top four-year-olds in the race as every Underwood winner from 2008 – 2013 won as a 4YO before Foreteller broke the streak winning as an eight-year-old in 2014.

Since then, the older horses have prevailed with Mourinho (8yo in 2015) and Black Heart Bart (6yo in 2016), but Bonneval (4YO in 2017) returned the younger gallopers to winning form in 2017. The 2018 Underwood Stakes winner was European expat Homesman who saluted as a five-year-old.

Black Heart Bart won his second Underwood Stakes as a veteran nine-year-old in 2019, while the four-year-olds were back in winning form in 2020 with Russian Camelot.

In 2021 European expat Zaaki won the Underwood Stakes as a lightly raced seven-year-old.

Alligator Blood then went back-to-back in 2022 and 2023 as a six and then seven-year-old respectively.

Buckaroo won the 2024 Underwood Stakes as a six-year-old before his second to five-year-old import Sir Delius in 2025.

Underwood Stakes tipping also favours horses drawn in a single digit barrier with only three of the winners from 2008- 2025 saluting from a wide barrier with the latest being Buckaroo (barrier 10 in 2024) and Sir Delius (barrier 10 in 2025). 

Any Kiwi-trained horses could also feature prominently in the Underwood tips as New Zealand horses have a strong record in the race with four wins since 2011 with Lion Tamer (2011), Ocean Park (2012), It’s A Dundeel (2013), and the mare Bonneval (2017). In 2021 the Kiwi-trained mare Probabeel was brave running second to the standout champion Zaaki.

2025 Underwood Stakes Tips

Our Ladbrokes’ insider Underwood Stakes 2025 betting tips and Melbourne racing selections will be detailed below the week of the race so stay tuned for the horses to back and sack in the Caulfield Cup lead-up race.

2025 Underwood Stakes Same Race Multi Selections ($8 at time of publish)

  • Top 3 – No. 2 Buckaroo
  • Top 3 – No. 9 Sir Delius
  • Top 3 – No. 10 Moira

BUCKAROO (8) is the reigning Underwood Stakes champion, and he shapes as a genuine contender to become just the 15th horse in history to win multiple editions of the race — the last being Alligator Blood in 2022-23. The imported seven-year-old son of Fastnet Rock has truly hit his stride over the past season, consistently holding his own against elite company. Buckaroo claimed last year’s Underwood in emphatic fashion, storming home by 3.5 lengths over Huetor third-up, with Joao Moreira delivering a masterful ride. He backed that up with a narrow second in the Turnbull Stakes — just a neck behind the stable’s future Cox Plate winner — before producing a gutsy runner-up finish in the Caulfield Cup. Even his ninth-place effort in the Melbourne Cup, where he jumped from barrier 20 and finished within 3.5 lengths of the winner, was full of merit. His autumn campaign was best forgotten, but he’s returned this prep looking sharper and more composed. Fresh in the Group 1 Memsie Stakes, Buckaroo was overlooked by punters but impressed over 1400m, finishing third behind the exciting mare Treasurethe Moment. That form was strongly validated last Saturday when Memsie runner-up Mr Brightside made history by winning the Makybe Diva Stakes for a third time. It all points to Buckaroo being primed for another big performance this Saturday. He’ll relish the step up to 1800m, benefits from a small field, and has drawn ideally in gate eight for Blake Shinn. Peaking at the right time — expect him to be right in the mix for a Top 3 finish.

SIR DELIUS (11) is an exciting import from the Waterhouse & Bott saddle and clear favourite for this year’s Underwood Stakes. This impeccably bred entire by Frankel is a rising staying star, lining up for just his ninth career start with an already impressive record of four wins and three placings. He showed serious promise in France, highlighted by a third-place finish behind Sosie in the Group 1 Grand Prix de Paris (2400m) last July, following a hat-trick of wins to kick off his career. Sir Delius made a strong impression on Australian debut, saluting as the odds-on favourite in Doomben’s Group 3 Chairman’s Handicap (2000m) under 60kg on a Heavy track — a gritty win that showcased his determination. The stable has taken a patient approach, keeping him lightly raced, and he returned in style with a strong performance fresh in the Chelmsford Stakes at Randwick. Despite the 1600m trip being short of his best, he was excellent — charging home from midfield to just miss behind Lindermann in a tight finish. Sir Delius oozes untapped potential and looks every bit a top-class stayer in the making. With natural improvement to come and conditions to suit, he shapes as a major player in the Underwood — and could well deliver for punters this weekend.

MOIRA (4) is a dual Group 1-winning Canadian import for Waller and is another well-supported runner in the Underwood markets. The classy seven-year-old Ghostzapper mare racing in the Yu Long Investments colours. She stamped herself as world-class last November with a commanding win in the prestigious Group 1 Breeders’ Cup Fillies & Mares Turf (2213m) at Del Mar. Her Australian debut didn’t go to plan, drawing the car park (barrier 18 of 20) and finishing 14th — beaten 4.9 lengths by Stefi Magnetica in the Doncaster. But she’s been steadily improving since. Moira showed encouraging signs when fourth in the PB Lawrence, hitting the line strongly, and backed that up with a close second in the So You Think Stakes — just a long neck off Desert Lightning. Both races look solid form references heading into the spring Group 1s. She’s proven over the trip and beyond, is clearly adapting well to Australian conditions, and has drawn perfectly in gate four with Damian Lane sticking. Now fitter and ready to peak, Moira shapes as a genuine each-way threat in the Underwood.

The Underwood Stakes is a weight-for-age race for staying types held at Caulfield Racecourse* in late September or early October each Melbourne Spring Racing Carnival. Held over 1800m under weight-for-age conditions the classic is open to horses aged three and over and is currently worth $1 million.

*In 2021 and 2022 the Underwood Stakes ran at Sandown Hillside.

In 2023 the Underwood Stakes Day card returned to Caulfield Racecourse having run at Sandown the past two years. 

First run in 1924 the opening two editions of the Underwood were both won by Whittier (1924 & 1925).

Other notable Underwood Stakes winners over the years include Phar Lap (1931), triple champion Ajax (1938, 1939, 1940), Rain Lover (1969), Bonecrusher (1986), Jeune (1994), Octagonal (1996), Northerly (2001 & 2002), So You Think (2010), It’s A Dundeel (2013), and Zaaki (2021).

It has been run as a Group 1 major since 1979 and often attracts graduates of the Memsie Stakes.

The Underwood Stakes is the feature race at the meeting in Melbourne with racing in Sydney on the same day dominated by the $1 million 7 Stakes at Randwick. 

In a calendar adjustment, the Group 1 Sir Rupert Clarke Stakes (1400m), a significant spring handicap, will move back from mid-November to its former position on Underwood Day in September. This relocation will once again make the September meeting a feature Group 1 double-header with the Underwood Stakes and renew its established link with the Group 1 Toorak Handicap (1600m), which takes place three weeks later on Caulfield Guineas Day.

The other key races on the Underwood Stakes Day card are the Group 1 Caulfield Guineas Prelude (1400m) and the Group 3 Naturalism Stakes (2000m).

In 2020 the Underwood Stakes ran on a Saturday and was won by odds-on favourite Russian Camelot who went on to frank the form with a next-up Caulfield Stakes second and third in that year’s Cox Plate trifecta.

In 2023 Alligator Blood successfully defended his title to become the 13th multiple Underwood Stakes winner in history and the first to go back-to-back since Northerly (2001-02).

Underwood Stakes Betting

Underwood Stakes betting markets really heat up the week of the race and are led by horses that ran top four in their final lead-up. Only two Underwood Stakes winner has finished worse than fourth in their previous run since 1997, the latest being Black Heart Bart (2019).

Plenty have won their lead-up race including Kiwi raider Ocean Park who took out the Group 1 Challenge Stakes back home and Bonneval (2017) who backed-up from a win in the Group 2 Dato’ Tan Chin Nam Stakes (1600m) – now run as the Feehan Stakes and most recently Zaaki who won the Tramway Stakes first-up ahead of his win as the $1.18 favourite in the Underwood Stakes in 2021.

In 2024 Buckaroo backed-up for a Group 2 Chelmsford Stakes win over the mile at Randwick in Sydney to win the Underwood. 

The Memsie Stakes meanwhile has produced a number or recent Underwood Stakes winners with the last to do the double being So You Think (2010). Black Heart Bart (2016) was the first favourite Underwood Stakes betting to salute for the punters since So You Think six years earlier. He also won again three years later in 2019 at $101!

Russian Camelot ($1.55 in 2020) followed by Zaaki ($1.18 in 2021) and then Alligator Blood ($3.60 in 2023) for his second victory in the event are the latest Underwood Stakes favourites to win.

Underwood Stakes Field

The Underwood Stakes race field traditionally attracts 10 or more starters including a full 16 in 2004 when Elvstroem saluted as a four-year-old, but in 2017 ran under that with just eight starters. The following spring the 2018 Underwood Stakes field also drew a small line-up of only nine hopefuls, before Zaaki scared off the bulk of the rivals with just five horses in the 2021 Underwood Stakes field.

There was another small six-horse Underwood Stakes field in 2022 with Zaaki returning only to run third behind Alligator Blood, while in 2023 Alligator Blood defended his title against a near capacity field of 14 rivals.

The 2024 Underwood Stakes field ran with 12 horses, while 11 lined up in 2025 when Buckaroo ran second in a failed title defence behind Sir Delius.

The field for the Underwood Stakes race is released on the Wednesday before the race runs as the marquee of that weekend’s Melbourne race meeting and features the season’s top weight-for-age hopes, many heading towards the Ladbrokes Cox Plate in a month’s time at Moonee Valley.

Horses traditionally come into the Underwood Stakes field via an earlier Melbourne lead-up run in a race like the Group 2 Feehan Stakes (1600m) or the Group 1 Makybe Diva Stakes (1600m) run at Moonee Valley and Flemington respectively.

Alligator Blood (2nd in 2022 and 2023) was the last Makybe Diva Stakes graduate to win the Underwood Stakes.

The 2022 Underwood Stakes form was further franked with the winner Alligator Blood also saluting at headquarters that November in the Group 1 Champions Mile (1600m).

Alligator Blood would go on to frank the Underwood form in 2023 with thirds in the Cox Plate and Champions Mile that spring. 

The 2024 Underwood Stakes form was franked by the winner Buckaroo who went on to run second in both the Turnbull Stakes and Caulfield Cup that spring.
