(CNN) She was trying to process an agonizing quarterfinal defeat at Wimbledon, but British No.1 Johanna Konta labeled a reporter "patronizing" and "disrespectful" after he questioned her big-match mentality.

The 28-year-old Konta had led 4-1 in the first set but succumbed 7-6 (7-5) 6-1 to unseeded Czech 33-year-old Barbora Strycova, prompting some probing questions.

Konta explained how difficult her opponent was, but one reporter pointed to her 33 unforced errors among a number of other issues and wondered whether she could have done better at key times.

"Is that in your professional tennis opinion?" she fired back.
