You shouldn't be, Boulter struggles with the expectation at Wimbledon. Further we had 21 in the MD this year, that is a massive improvement over the last 10 years.The LTA have to answer for the situation of British tennis. Our most promising players are constantly injured or under-performing. I am really surprised by Boulter.
With the exception of Norrie, every single one of our players yesterday was the underdog but most of them competed well, not looking out of place.
There are plenty of players from other Countries that suffer constant injuries, Andreescu has had a horrible time (and also lost yesterday) since she won the US Open.
