Matteo Berrettini beat Stan Wawrinka 7-6, 7-6, 6-0 at the US Open, winning two tight tiebreaks before closing out the match with a dominant third set. His serve held up under pressure all the way through.
Berrettini broke for 3-2 in the opener, only for Wawrinka to level at 5-5; Berrettini then took the tiebreak. Wawrinka moved ahead with a break at 1-2 in the second, but Berrettini broke back at 5-5 and won another tiebreak. In the third set, Berrettini broke at 1-0, 3-0 and 5-0 to complete a 6-0 set.
Berrettini finished with 13 aces and won 12 of 14 service games, saving 10 of 12 break points. Wawrinka, by contrast, saved only two of seven break points and was swept away by Berrettini's six-game surge at the end.
