I cant see any juniors getting a MDWC. Mimi is doing well and results may warrant it in the run up. Argument for Mika having won the US Open Juniors but Hannah is now Junior WR3 and got to the FQR of the main Wimbledon qualies last year, so it is both or neither??
Historically, there have been a fair few MDWC given to people outside of GB players and I would expect more than 4 or 5 for our players (in men too).
