Andrey Rublev and Felix Auger-Aliassime each have demons to contend with when they step onto the court at the Billie Jean King National Tennis Center on Monday.

A win for Rublev on Monday would send him to a 10th Grand Slam quarterfinal, where he’ll look to snap an 0-for-9 streak that has haunted his career.

Rublev has spent years as a top 10 player, and he’s won two Masters 1000 titles, but he’s never had his breakthrough moment at a major.

The Russian likely won’t get a better chance than this to get off the schneid, as his potential opponents in the quarters would be Alex de Minaur or Leandro Riedi.

Auger-Aliassime, meanwhile, went to the semifinals at the 2021 U.S. Open as a 21-year-old, a performance that got tongues wagging that the Montreal native was going to be a part of the contingent of players that would carry the torch after the Big 3 retired.

Auger-Aliassime’s career has been stop and start since then, plagued by injuries and inconsistent tennis.

The Canadian’s attacking tools, notably his serve, are elite, but his all-around game never caught up.

That’s turned him into a high-ceiling, low-floor player who can beat anybody on his day — as we saw in his win over No. 3 Alexander Zverev last round — but also loses matches to inferior opponents.

Rublev can spiral during a match, too, but his multifaceted skill set seems to be a good match for Auger-Aliassime’s aggressive style.

Rublev and Auger-Aliassime have met eight times in their careers, with the Russian taking seven wins.

We’ll back the more consistent player as a slight favorite on Monday.
