Matteo Berrettini vs Stan Wawrinka — R128 — US Open

Only one of them cashed his chances on return. Wawrinka built 13 break points and took two, 1 of 8 in the second set alone, while Berrettini converted five of seven — the one that counted in game 10 for 5-5, off a serve one game from levelling. Their only meeting on record, a June opener at Wimbledon, needed a tiebreak in all four sets, and this held the same shape until Wawrinka's final set came apart at 12 unforced errors to four winners. Berrettini won 91% of his first-serve points from there and had it closed inside 2 hours 53 minutes. He moves on 4-4 on hard courts this season, beaten in two of his last three coming in.
