Things at the US Open are starting to heat up, and by the close of play on Monday the quarter-finalists will all be known.
Defending men’s champion Carlos Alcaraz is one player expected to be in the mix and the Spanish sensation should have few concerns against fourth-round opponent Matteo Arnaldi.
Elsewhere, Daniil Medvedev takes on Alex De Minaur in a cracker while in the women’s draw world number two Aryna Sabalenka meets Daria Kasatkina.
To embrace the action, we’ve picked out three selections for punters to enjoy.
Alexander Zverev to beat Jannik Sinner @ 5/4
This is one of the clashes of the day as world number six Jannik Sinner meets 2020 US Open runner-up Alexander Zverev and the Italian could be vulnerable.
After a few injury scares, Zverev is back playing some good stuff and he comes into this encounter having lost only two of his last 15 matches.
Zverev warmed up for the US Open with a run to the semi-finals in Cincinnati and at the end of July he claimed his 20th career title when winning on home soil in Hamburg.
Interestingly, Zverev has won his last three meetings with Sinner and he could confirm that form against the Italian, who needed four sets to come past Swiss veteran Stan Wawrinka in the last round.
Madison Keys to beat Jessica Pegula @ 6/4
There may be a surprise in this all-American encounter with Madison Keys a lively outsider to cause a stir against compatriot Jessica Pegula.
Keys finished runner-up to Sloane Stephens at the US Open in 2017 and she is back performing as well as ever, highlighted by her run to the quarter-final at Wimbledon last month.
The 28-year-old impressed in coming from behind to upset Liudmila Samsonova in the last round and she could back that up against Pegula, who was pushed hard by Elina Svitolina most recently.
World number three Pegula needed three sets to see off the Ukrainian and she has never gone beyond the quarter-final of a Grand Slam, which suggests her world ranking may flatter her.
Marketa Vondrousova to win 2-0 vs Peyton Stearns @ 1/2
Marketa Vondrousova is going quietly about her business and the Czech world number nine should have too many gears for American youngster Peyton Stearns.
Vondrousova has won her opening three assignments at the US Open in straight sets and that includes downing the talented Ekaterina Alexandrova last time out.
And the 24-year-old can repeat the trick against Stearns, who has profited from a generous draw and is appearing in the fourth round of a Grand Slam for the first time.
Vondrousova has lost only two of her last 17 matches and she can prevail 2-0 against the American, a player she defeated 6-2 7-5 at Wimbledon in July.
