4. In his country he is only active player, who reached the quarterfinal on Wimbledon. He was №90 at that time and lost to player who was world №5.
I didn't understand the question correctly. I was looking for someone who is the only current active player for his country. The comma in between "active player" and "who" got me wrong.
You are no the only one here
I went to Wikipedia for the QF results from Wimbledon for the last years and I thought, well there are always more players from this country.
Then I decided to read the question again
I feel kind of bad for those who lost with more than 5 times of my score
