Emma's next match is scheduled for "not before 3am Wednesday" UK time, 8pm local time. So it looks as if it will be under floodlights.

Emma lost  the 1st set 6-3 against Iga.

Rather predictably, Emma got destroyed in the painfully slow night time conditions in Indian Wells. Her first serve had almost no penetration, one ace and 2 unreturned first serves all match. Very few first serves landed near the lines, while the speed was understandably slower than in her previous two matches. She had marginally more success on 2nd, winning 50%.

When the prediction model gave Emma 11% chance of winning before the match had started, Laura Robson commentating on Amazon Prime seemed surprised it was so low; I thought it should have been 5% (possibly as high as 20% had it been afternoon sunshine with a day off between matches). 

The early stages of the first set were fairly tight. Raducanu saved 2 bps helped by a Swiatek error on the first, then good play, finishing with a forehand winner on the 2nd, a nice drop shot to take her opening service game. An aggressive forehand return off a 2nd got Emma to 15-30, only to make a careless forehand error long for 30-30, Raducanu backhand pass winner brought the score back to 40-40, then a lovely drop shot from Emma to force break point but Swiatek saved it with a forehand winner. A rare error from Iga gave Emma another bp but her return off a 1st was into the net.

Emma held to 30 thanks to several Swiatek errors, despite only landing 2 out of 6 first serves. Iga to 15 for *2-3. Emma looked to punish any 2nd serves, a super backhand return winner for her single point. At other times, Iga managed to get the ball deep despite Raducanu blasting returns near her feet. Swiatek's defensive skills in these conditions are so impressive. 

A poor Raducanu forehand into the net when dominating a rally, then later a df as she was broken to love. Then a drop shot error from Raducanu and a backhand crosscourt error on another point she could have won as Swiatek held to love for *2-5. A pair of forehand winners from Raducanu as she went up 40-0 then lost the next two points before a backhand error wide from Swiatek allowed her to hold for 3-5*. A comfortable hold for Swiatek, including her 5th and 6th unreturned 1st serves, to take the opening set 3-6

Raducanu smash winner on another of those typical Indian Wells points when the ball keeps coming back. An ace T and a super backhand winner after 2nd to hold at the start of the 2nd set. Swiatek landed all six first serves as she held to 30. Despite three 2nd serves, Emma was up 40-15 after a forehand pass winner, a good backhand down the line and a deep 2nd serve, but the lack of penetration on her first serve was evident as she lost the next two points, Swiatek in control both times. A poor error from Emma on a forehand after a 2nd gave Swiatek bp, that she wasted with a forehand error crosscourt, Raducanu poor forehand error long, presented Iga with a 2nd bp, saved by an aggressive backhand crosscourt from Raducanu. A df for bp number 3, Iga's return off a 2nd into the net, Emma saved a 4th bp with a good wide 1st serve, then two horrible forehand errors from Raducanu, the 2nd after impressive defence from Swiatek, cost her the break 1-2*.

The commentary caught coach Sachs telling Emma that her ball was sitting.

From then on it was far too easy for Swiatek, she seemed to have time to hit whatever shot she wanted. Raducanu defended but had no penetration on her shots, so ended up merely extending the rally by an extra shot or two. When Raducanu did have a slight opening to be aggressive, she made awful errors as she collapsed to a 3-6 1-6 defeat, winning just 2 points out of the last 20.
