MTF is your friend(I used MTF to find 3 answers). For that one I went to the challenger forum, and used the search function and searched "3 matches in 1 day" and found the Nottingham thread as the 5th or 6th thread returned. It took some time having to go through the first few and realize they were not right, but when I got to Nottingham I saw a post about people talking about 3 matches in 1 day by Matosevic. Took maybe 20 minutes.
I remembered that happening this year but couldn't remember the player but remembered it was talked about on MTF so that's why I searched here
