Emma Raducanu calls for a medical timeout and receives some assistance to stretch out the hip, groin and back regions.

I think we’re going to be playing each other many more times in the future. This is the first time. And it’s gonna be a good match. I think she’s a tough opponent. She took some time out, obviously, off the tour, for sort of mental health reasons and just to find herself again.

The Australian contingent has seen better days at their home grand slam, with Jordan Thompson and Ajla Tomljanović among the locals to exit the tournament along with Thanasi Kokkinakis.

Tumaini Carayol was at Melbourne Park to cover the match of the tournament thus far.

While Jack Snape sat in an at times emotional press conference with Kokkinakis, who was one game away from progressing to the third round but in the end succumbed to injury and an equally determined opponent in Draper.

I know I don’t have forever left, so I don’t know how long I’m going to be out [injured], or what the future holds, even if I can get back to this point if I get [surgery] done. So I’m just [in] a lot of doubt and pretty upset. One thing’s for sure I can’t keep doing what I’m doing, it’s mental torture and physical torture.

Now for the weather. The clouds have returned after rain interrupted day four – at least on the outside courts – on a confusingly wintery summers day. The forecast is only slightly better for today but the eye-test tells us that we should get a lot more tennis in.
