Peterson came up with some big second serves to recover from 30-0* to game point, but Heather kept her under pressure and drew 3 errors to get over the line. The whipped backhand crosscourt was doing real damage, both as a low tight angle and also hard and deep into the corner.
Another really clean, solid performance. The sort we've missed seeing regularly. Well done, thought the third could get messy given recent times but she kept to a high level and served well.
There was only one lower ranked qualifier so Heather's draw couldn't have got much better. Mind you Sasnovich probably also thinks she has a pretty good draw.
