Al Riffa has stormed into Melbourne Cup calculations with a commanding victory in the Group 1 Irish St Leger (2816m) at the Curragh, run in the early hours of Monday morning (Australian time). The Joseph O’Brien-trained entire was making his debut for Australian Bloodstock, who secured the six-year-old earlier this year, and wasted no time stamping himself as a genuine contender for Australia’s richest staying prize.
The performance was emphatic. Al Riffa coasted home four lengths clear of his rivals, showing both class and stamina in a display that has seen bookmakers shorten him to as little as $6 for the $10 million Melbourne Cup on November 4.
For O’Brien, who already has two Melbourne Cups on his CV courtesy of Rekindling (2017) and Twilight Payment (2020), the win provided further evidence of his stable’s ability to target and prepare European stayers for Flemington’s famous two miles.
“He’s a multiple Group 1 winner, so he’s going to carry a lot more weight, but he’s going to carry it because he’s a very high-class horse,” O’Brien said post-race. “Whether he can win carrying the weight, we’ll find out, but he is a classy horse and he does have some of the right attributes that we think you need for the race. We’re excited to hopefully get a smooth passage down there.”
Rising in the Betting Market
Al Riffa’s decisive win immediately reshaped Melbourne Cup markets. Prior to the Irish St Leger, the stallion was considered a strong chance, but his price has since firmed sharply, reflecting punters’ growing confidence in his credentials.
The timing of the victory could hardly be better. Racing Victoria’s chief handicapper David Hegan is set to release Melbourne Cup weights on Tuesday, a critical moment in determining the scale of Al Riffa’s challenge. As a proven Group 1 performer with elite staying form, the horse is expected to be allotted a hefty impost, but that has not deterred either connections or punters.
A Proven Group 1 Star
The Irish St Leger was not just another win for Al Riffa — it was his third Group 1 triumph. He first announced himself as a star juvenile with victory in the National Stakes (1408m) at two, before capturing the Grosser Preis von Berlin (2414m) last season.
His consistency at the elite level is undeniable. Leading into the Irish St Leger, Al Riffa had won the Curragh Cup (2816m) and finished a gallant runner-up in the Hardwicke Stakes (2414m) at Royal Ascot. With form lines through some of Europe’s best middle-distance and staying contests, he now shapes as one of the most accomplished international raiders preparing for a tilt at the Melbourne Cup.
Dylan Browne-McMonagle’s Key Role
Integral to Al Riffa’s success has been the partnership with Dylan Browne-McMonagle, who has been aboard for all of the horse’s recent starts. The young Irish jockey is no stranger to Australian racing fans, having spent time riding for Ciaron Maher, and his growing international reputation only strengthens Al Riffa’s Melbourne Cup credentials.
Browne-McMonagle was also booked to ride Asfoora in the Group 1 Flying Five Stakes (1005m) at the same Curragh meeting. However, the Henry Dwyer-trained sprinter could not reproduce her sparkling Nunthorpe Stakes win at York, finishing seventh in a disappointing effort. For Al Riffa, though, it was the perfect showcase, reaffirming the strength of the O’Brien-Browne-McMonagle partnership.
The Road to Flemington
Connections are under no illusions about the task ahead. The Melbourne Cup is renowned for its unpredictability, demanding both stamina and tactical adaptability, and Al Riffa will need to overcome the added burden of weight. Still, his proven versatility across distances from 1400m to 2800m, combined with his established Group 1 class, places him firmly among the top tier of contenders.
Australian Bloodstock, who have a strong history of targeting European imports for the Cup, will take immense confidence from his latest performance. The syndicate has long believed in sourcing proven European stayers and transitioning them to Australian conditions, and Al Riffa now looms as one of their most promising recruits yet.
O’Brien’s Melbourne Cup Legacy
For Joseph O’Brien, still only in his early forties, the Melbourne Cup has already become a defining race. His 2017 victory with Rekindling made him the youngest trainer in history to win the race, while Twilight Payment’s bold frontrunning triumph in 2020 confirmed his status as a master conditioner of stayers.
With Al Riffa, O’Brien now has the chance to join an elite group of international trainers to win the Cup three times. His comments reflect both excitement and respect for the challenge: “Whether he can win carrying the weight, we’ll find out, but he is a classy horse and he does have some of the right attributes that we think you need for the race.”
The Australian public has often embraced international challengers, particularly those carrying the O’Brien name, and anticipation will only grow as the countdown to November continues.
Looking Ahead
The release of weights on Tuesday will provide the next major talking point in Al Riffa’s Cup journey. With bookmakers already positioning him at the top of the market, his allocation could dictate how the narrative unfolds in the coming weeks.
If the six-year-old can maintain his form and adapt seamlessly to Australian conditions, he will arrive at Flemington as one of the most credentialed and exciting international contenders in recent memory. For now, his Irish St Leger demolition has set the scene for a fascinating spring, with Al Riffa looming as the horse to beat.
