Del Potro’s title tilt looks set to gather pace against Thiem
Austrian not sure to find more against towering Argentinian
Eurosport 1 & 2, from 4pm Monday
Del Potro v Thiem
Dominic Thiem has not been starring on hardcourts this season and the Austrian could be there for the taking when he meets Juan Martin del Potro on Labor Day.
It was difficult to know quite where Del Potro's game was after an easy couple of opening rounds but his third-round opponent, Winston-Salem champion Roberto Bautista Agut, was seen off 6-3 6-3 6-4 in fine style.
A repeat of that form should help the towering Argentinian, winner of the US Open in 2009, to frank his two previous victories over Thiem, who failed to convince when silencing Taylor Fritz in round two.
One swallow does not make a summer, as they say, but Delpo's latest display will at least give heart to his backers that he can again challenge for another New York Grand Slam crown.

Kasatkina v Kanepi
Daria Kasatkina won her only previous clash with Kaia Kanepi but the young Russian looks too short in the betting to add to that triumph.
Kasatkina defeated the Estonian 2-6 6-1 6-1 on clay in St Malo in 2015, but there is a lot more at stake in their second meeting and Kanepi's greater experience could be a big factor.
Kanepi found it difficult in her main-draw opener against Francesca Schiavone, who was trying to put on a decent show in her final singles outing at Flushing Meadows, but Yanina Wickmayer proved less of a problem for the qualifier before the useful Naomi Osaka was ousted in three sets.
Kasatkina has dropped only one set in the tournament, against Qiang Wang in round one, but Kanepi could prove a redoubtable rival and she can win at least a set.

1pt 4-6 Betway
David Goffin could be the one to end Andrey Rublev's run in New York but a price of 1-2 hardly screams value against one of the best youngsters in the game, while top seed Rafael Nadal may have to toil to see off Alexandr Dolgopolov.
Karolina Pliskova, who has come from a set down to win her last two singles outings, will fancy her chances of progressing against Jennifer Brady, although the American is a bright prospect.
