My pick: Alex Michelsen to advance · locked 2026-09-05 01:40 UTCPrediction
Neither of these two had reached the fourth round of the US Open before this week, and they have never played each other, so this is a match with no history on either axis — which leaves the surface. Etcheverry is a clay-court player who has arrived in the second week of a hard-court major: his career record on hard is 53-58, a losing one, against Michelsen's 74-54, and he came to New York without winning a match in Washington, Montreal or Cincinnati. Michelsen's hard-court Elo is 114 points higher, which is about two-to-one. The counterweight is that Etcheverry has been the better player of the two for a fortnight rather than a season. He beat Vít Kopřiva, then Jacob Fearnley across a rain interruption, then his compatriot Mariano Navone — who had put out Novak Djokovic — in straight sets, dropping serve once in three matches on Friday's evidence. At 6'5" he serves a heavy ball and he won 66% of his second-serve points in that match. Michelsen's week is the more impressive on paper: he beat the 16th seed Brandon Nakashima in straight sets in the second round and then made fourteen unforced errors in three sets against Daniel Merida, which is a remarkable number for a 22-year-old in a Grand Slam third round. That control is the thing most likely to decide it. This is the section Djokovic vacated in the first round, so a quarter-final is genuinely on offer to whoever wins. Michelsen.
The case for Tomas Martin Etcheverry
32% to winEtcheverry has won three matches in New York without looking like the man whose season record is 25-22, and one of them was against the player who beat Novak Djokovic. He is 6'5", served eight aces to four against Navone and won 66% of his second-serve points, and at 27 he has five more years of tour matches behind him than Michelsen. His route here included a match interrupted for hours by rain, so he has already proved he can hold a week together. He has never lost to Michelsen because they have never played, and a 27th seed who has just reached the fourth round of a major is not the same player as the one who lost his opener in three straight hard-court events in August.
The case for Alex Michelsen
68% to winMichelsen is the better hard-court player by every available measure: 74-54 on the surface for his career against a losing 53-58, and a hard-court Elo 114 points higher. He beat the 16th seed Brandon Nakashima in straight sets and then made only fourteen unforced errors in three sets against Daniel Merida while winning twenty-five of thirty-six approaches — control and net play, on the surface that rewards both. He is 22, 6'4", and this is the first time he has been past the second round here, which means everything about the week is upside. He is also the fresher of the two by a set.
Both cases written 2026-09-05, 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.

At this Stage
The Round of 16 is the fourth round, and the point at which a Grand Slam stops being a draw and becomes a tournament you can hold in your head: eight matches, played across Sunday and Monday, and the eight who come through are the quarter-finalists. Everyone still here has won three matches on these courts, so the seedings have stopped being a guide and the form of the fortnight has taken over.
