It's an all-Australian affair at the US Open on Monday when Alex de Minaur and Jordan Thompson face off on Louis Armstrong Stadium with a place in the quarter-finals up for grabs.
World no.10 De Minaur has seen off Marcos Giron, Otto Virtanen and Great Britain's Dan Evans to reach this stage at Flushing Meadows for the fourth time in his career, while Thompson is in the form of his life and is appearing in a Grand Slam fourth-round singles match for only the second time.
The 30-year-old has impressed in New York with wins over Constant Lestienne, Hubert Hurkacz and Matteo Arnaldi and he's 11/4 to progress to the quarter-finals with De Minaur the 2/7 favourite.
Alex de Minaur to win & both players to win a set - 6/5
Alex de Minaur has won four of his five head-to-head meetings with Jordan Thompson and it's no surprise to see that dominance reflected in the match prices with De Minaur odds-on to progress to the New York semi-finals for the second time.
The 25-year-old has been in fine form all year, briefly rising to a career-high sixth in the rankings and reaching at least the fourth round of all four Grand Slams, and he will again be eyeing a deep run after Carlos Alcaraz's shock exit from this quarter of the draw.
Best known as a counter-puncher with tremendous court speed, De Minaur has worked hard to add power to his game and, while that remains an issue when he comes up against the very best, it appears to be paying off and has been reflected in his results.
The Sydneysider has looked solid in his three New York outings, although he did drop sets in his wins over both Marcos Giron and Dan Evans and a similar outcome looks likely in this fourth-round clash.
Thompson has never taken a set off his compatriot on a hard court but he has also never been playing as well as he has over the last month, reaching the Atlanta final and losing out to two high-class rivals in Sebastian Korda in Washington and Alexander Zverev in Montreal, before a rib injury forced him to withdraw in Cincinnati.
The 30-year-old has registered three straight-sets wins in the Big Apple and while his record against his compatriot suggests he's an unlikely winner of this one, he can put up a fight and can claim a set in defeat.
Ace totals - 20+ aces in the match - 9/4
Neither De Minaur or Thompson are renowned as huge servers but the Aussie pair could rack up the aces, particularly if this match goes beyond a third set.
Despite winning all three of his matches in straight sets, Thompson has averaged 11 aces per match at the US Open. He's facing statistically the best returner on the ATP Tour but that shouldn't drastically reduce his ace numbers if he gets his first service in with regularity.
De Minaur, meanwhile, had to lean on his serve in his victory over Evans, thundering in 11 aces to see off the Briton in four sets, so he could also keep the ace count ticking over on the New York courts, which have been relatively fast over the opening week.
Fifteen or more match aces is priced up at 4/5 but, with a long match potentially in the offing, it could pay to take a chance on 20+ aces at 9/4.
