The first round of the U.S. Open is underway, and I have a parlay to share for Monday’s matches.
The latest: Canadian Gabriel Diallo will compete in his second U.S. Open and looks to build on last year’s success. He plays Damir Dzumhur in his opening match. On Court 5, Andrey Rublev will welcome Dino Prizmic in his debut at the event.
Check out my top US Open picks for the first round of action, featuring a pick on Karen Khachanov vs. Nishesh Basavareddy.
US Open parlay picks: First round
Parlay: Diallo -1.5 sets | Rublev -1.5 sets | Basavareddy over 17.5 games won (+403)
Diallo -1.5 sets (-180): The Canadian is finding his footing at the ATP Tour level, and there’s definitely been some mixed results.
His 13-12 hardcourt record is nothing special, but it’s not bad either. Plus, I believe he has the momentum on his side in this matchup.
- Diallo’s results need to be taken with a grain of salt. Four of his last five losses have come against Taylor Fritz x2, Ben Shelton and Jannik Sinner. All of which rank inside the top six.
- On the other side, Dzumhur is 20-20 on this surface since the start of last season, and he’s been struggling regardless of his opponent. He’s lost eight of his past 13 matches.
The 33-year-old has been eliminated in the first round at 10 events this season, including two of the three Grand Slam majors.
With one set to work with, I expect Diallo to cover this line.
Tennis parlay picks
Rublev -1.5 sets (-148): Rublev is having a down year by his standards, but he’s still a very consistent player.
Of the 20 events he’s competed in, he’s only been eliminated in the first round twice.
As the 15th-ranked player on Tour, he often has the benefit of playing a lower-quality opponent, and that’ll be the case again at the U.S. Open.
He draws Prizmic in the opening round. The 124th-ranked 20-year-old has spent most of his career on the Challengers Tour.
Prizmic has already played three games at Flushing Meadows, as he needed to qualify.
He is 35-8 in his career on outdoor hardcourts, so he’s certainly a promising talent. But I believe it is still too early for him on the grand stage.
Prizmic has played just two top 100-ranked opponents in his last 11 matches, and he’s 0-2 in those matches, losing four of the five sets.
Rublev is 204-106 on hardcourts in his career and should be able to advance comfortably through the first round.
Basavareddy over 17.5 games won (-109): I’m officially placing this match on upset watch.
When Basavareddy made his Grand Slam debut at the Australian Open this year, he took the first set off Novak Djokovic before ultimately losing.
He’s a beast on hardcourts, going 16-9 on the surface this season, with a 61-26 career record.
Khachanov is no slouch, but he’s played a ton of tennis lately, thanks to a deep run at the National Bank Open.
Because of that, he needed to retire from his last match with Alexander Zverev due to a “physical issue” he could no longer deal with.
That doesn’t give me confidence in the 29-year-old moving into the final part of the season.
Basavareddy is 4-1 in his last five matches played. This line doesn’t require him to win but just to keep it close in a three-set match against a fading competitor.
