Errors creeping in on SW's serve at 1-2. Ad ND.
But ND overhits it & it's back to deuce. SW's fist serve is a liability but he won the point & game after a mediocre second serve.
It's noteworthy that ND can't capitalise on the poor first serve of SW, and that although he put a lot of pressure on SW in that 4th game, he couldn't convert his break points.
What an exquisite backhand from SW to take it to 30-30 on ND's serve.
EDIT : deuce. Another beautiful backhand from SW to get the ad. But then over hits a shot to go to deuce. This is just wonderful play. Ad to SW. And some exquisite shots to get the break. SW 3-2 & to serve next.
