My pick: Arthur Rinderknech to advance · locked 2026-08-31 03:00 UTCPrediction
Rinderknech, on recovery time as much as anything. These two are a genuine coin-flip on paper — 1–1 lifetime, both meetings on hard courts, career records within a few matches of each other — so the tiebreaker is what each of them spent to get here. Munar came from two sets down to beat Terence Atmane 6-7(5) 3-6 6-1 7-6(4) 7-5; Rinderknech dropped the opening tiebreak to Sho Shimabukuro and then closed it out in four. The seeded Frenchman is also the bigger server by five inches of height, which is the shot that travels best on this surface and the one that costs least to hit. Munar's counter is that he owns the more recent meeting, in Miami last year, and that both men reached the fourth round here in 2025 — this is familiar ground for each of them. It should be close. It should also be shorter for the man who has spent less.
The case for Arthur Rinderknech
53% to winThe Frenchman is the seed, the higher-ranked player at No. 29, and the one with the better career hard-court record — 87–90 against Munar's 68–91. Thin margins, but they point the same way, and they sit on top of a serve delivered from 6′5″ on the fastest surface either man plays. Most of all he is fresher: four sets against Shimabukuro, against five from two down for Munar. Their one meeting on Rinderknech's terms, Metz in 2022, he won 6-2 2-6 7-5.
The case for Jaume Munar
47% to winMunar has the more recent win — 6-3 7-6(5) at the Miami Masters in March 2025, on a hard court, in straight sets — and he has just proved he can survive a bad start at this tournament: two sets down to Atmane, and through in five anyway. He matches Rinderknech's fourth round here last year, so neither man is out of his depth at this stage of this event. A five-setter cuts both ways, too: the legs are heavier, but the timing is grooved, and Munar has now spent the better part of four hours reading this court's bounce while his opponent spent rather less.
Both cases written 2026-08-31, before the first ball — frozen into the record exactly as written, whatever the result. The percentages are mine — opinions with a percent sign on. They add to 100 because tennis has no draw to hide the rounding in.

Weather: Rain shapes the opening days. Showers and thunderstorms stay possible through Sunday night under a low near 72°F. Monday is the driest day of the window — partly sunny, high near 77°F, a 20% shower chance before 5 p.m. — before showers return after 8 p.m. Tuesday is warmer and wetter: mostly cloudy near 82°F with a 50% chance of showers and thunderstorms, mainly mid-afternoon and again overnight. Wednesday holds near 79°F on the same 50% odds, and Thursday is warmer still — partly sunny, 83°F, storms possible either side of the day. Ashe and Armstrong close their roofs; the field courts wait.

At this Stage
The Round of 64 is where a Grand Slam draw stops being a lottery and becomes a tournament. Sixty-four men's matches opened the bracket; thirty-two across Wednesday and Thursday halve what is left, and everyone still here has already won on these courts. Seeds who came through the first round now meet opponents carrying form rather than a ranking.
