unforced

In a performance well below his high standards, Djokovic made 37 unforced errors and only hit 16 winners to mitigate the damage.

With the sides in such contrasting form, Ireland's unforced changes may lead to more in Wales thinking that their visitors have not arrived with full focus.

The pair traded breaks in the second set but Gauff's game broke down, with the 20-year-old committing 25 unforced errors and six double faults.

“We were moving the rock really well the last two drives and just a couple unforced errors here and there.”

More double faults and a flurry of unforced errors indicated Alcaraz's tension, allowing Draper to break back in the ninth game and hold more confidently to level the set.
