unforced

By the end of the first set, Anisimova had hit 15 unforced errors to 13 winners and won less than 50% of points on her own serve.

His frustration came to a head in the seventh game of the third set when he received a time violation and committed three unforced errors to hand Vacherot the break.

But she failed to convert two break points in the next game and a series of sluggish unforced errors then helped Li break for a 2-1 lead.

Anisimova, who hit 17 unforced errors in the second set after just four in the first, improved in the decider and broke Noskova in the sixth game before going on to claim victory.

She is seeking to head off a challenge from rival Lucy Powell, who has attacked "unforced errors" on welfare since being sacked from the cabinet this month.
