You think of that, not a sweat . Weve been asking the question of journalists following her through the year, is tree as good as 2016 when she won the Australian Open, the us open and even pigs and people saying she is better. And 0lympics. She has changed her coaching setup. She is enjoying herself, she is smiling too on court. Its a good matchup with madison keys, madison keys, big hitter, us open finalist, but in terms of ahead to head it is skewed towards the german, she uses the pace of keys, she counterpunch to perfection. You mentioned the scoreline and the time, seven u nforced scoreline and the time, seven unforced errors. What this win will also do, not only put her in the australian semi finals, but it will put her into the top ten because she went to the mid 20s last year. Having been a former world number one. She is sensational, unbeaten so far this year and shes only dropped one set this year and that was in the fourth round. Incredible tennis, really good to watch, warming us up with chungs defeat of Novak Djokovic and also sandgren on now on the replay, are we looking forward toa the replay, are we looking forward to a big showdown between these two youngsters .

Then you have sandgren, a bit ofan to watch. Then you have sandgren, a bit of an unknown, 97 in the world. His debut in australia, never won a grand slam match before this year and then hes in the quarter finals and then hes in the quarter finals and hes done it the hard way, he defeated number nine seed wawrinka, not fully fit, though, after knee surgery, not fully fit, though, after knee surgery, then dominic thiem, you cant say hes not fully fit, he a lwa ys cant say hes not fully fit, he always is. He came through that one in five hours. Hes looking relaxed, hes playing his tennis, enjoying his tennis and would you believe the 58th ranked chung or the 97th ranked sandgren will be in the australian 0pen semifinals, its incredible to think we moments away from them walking out to rod laver and im excited to see how they get on and how they perform on this court, will the nerves get to them . They both have big games so it will be exciting. Both came in believing and one dream is going to come true. Thanks for talking to us from melbourne park. The worlds number one tennis player has hit out at the atp tours gruelling schedule, saying organisers need to think about the health of the players. Rafa nadal retired hurt from the Australian Open in the fifth and deciding set against marin cilic. Somebody who is running the tour should think a little bit about whats going on, you know . Too many people getting injured. I dont know if they have to think a little bit about the health of the players not for now, when we are playing, but there is life after tennis. I dont know if we can keep playing in these very harsh ways what will happen in the future with our lives. I am a positive person. I can be positive. But today its an opportunity lost for me to be in the semifinals of a grand slam to fight for an important title for me. In this tournament its already happened a couple of times in my life. So really, i dont wa nt to times in my life. So really, i dont want to say frustration, but its really tough to accept. Hes pretty riled up.

Wednesday is going to bring some fairly disturbed weather across the country, courtesy of what the Irish Weather Service have named storm georgina. Across the uk it will bring gales and heavy rain, which could cause travel disruption. Your local bbc Radio Station will keep you up to date with that. Heres the storm drifting across the north west of scotland. Notice all the white lines, the isobars on the chart. That shows we will have pretty strong and gusty wind, showers feeding in around the low across scotland during the first part of the morning and these, to give you an idea of the wind gusts were expecting, 50, 60, 70 miles an hour in exposed spots. Gusty winds and showers into northern ireland. As we drift down across england and wales, a band of heavy rain, and intense downpour accompanying particularly squally and gusty winds. That rain band with the gusty winds will only track slowly eastwards as we head on through the day. Lets run wednesdays weather through. Windy wherever you are, a band of rain sinking south and east across england and wales with gusty wind. Behind the rain band, bright skies. Spells of sunshine. Showers chasing along into western areas, they could be wintry showers over high ground in the north because you will get into some slightly chilly air. 6 10 degrees by the end of the afternoon, actually one of those days where the temperature drops away as the day goes on. Into wednesday night, it will be a cooler night generally, a f e h thursday itself, actually not a bad day for many. Spells of sunshine around. Still some showers drifting in from the west. A little area of low pressure drifting across the country, acting as a focus for those showers moving eastwards. As far as the temperatures go on thursday, still that slightly fresher feel, 5 9 degrees. Although actually for the time of year, thats not too bad. That area of low pressure responsible for showers should drift away on thursday night and then we try to bring in this bulge of high pressure, this little ridge toppling in from the west. If the timing is right it could give some frost to start friday morning, but it should bring a decent day. Some spells of sunshine. Rain into the far north west later perhaps temperatures of 4 9 degrees. What about the weekend . After a slightly chilly couple of days to end the week, the temperature should start to climb again. Cloud and rain in the north west but hopefully some sunshine too. Welcome to bbc news, broadcasting to viewers in north america and around the globe. My names mike embley.
