Iain Bates was watching Harriet's match. Not sure who was with Harriet this week, if anyone.
Some big ''Eastern European looking'' guy was talking[in perfect English] to Harriet and Katy Dunne after their doubles win over the number two seeds earlier in the week. During her match against Emma Raducanu whichever day that was,the same guy was watching and making copious notes as the match progressed .I would guess it was him.
