A furious Johanna Konta refused to shake hands with umpire Paula Vieira Souza after a narrow loss to Ashleigh Barty in the final of the Nature Valley Open in Nottingham.
The British No 1 had battled back from 4-1 down in the decider and had Barty under pressure on her serve when a shot from the Australian appeared to land long, but neither the line judge nor Souza called it out.
Konta confronted Souza, saying: "It's an absolute joke. You're making decisions that affect our lives. Do you fully understand that?"
She won only one more point and after a final passing shot from Barty clinched a 6-3 3-6 6-4 victory, Konta walked straight past Souza and off the court.
Several minutes passed before she returned for the trophy ceremony, although she would not say whether she was complaining about what had happened.
It is not the first time the 27-year-old has refused to shake an umpire's hand, and she said: "At 4-4 in the third set, that's quite an important time of any match. It's a difficult position to be in.
"I definitely burned through quite a bit of energy at that moment in time. But, except for one loose shot [in the last game], I don't think I did too much wrong. Obviously I'm a little bit sad I could not come through with the win today but I'm also taking a lot of positives from this week in general."
Konta was playing in a final for the first time since doing so here 12 months ago, when she lost to Donna Vekic. It has been a difficult season for a player who was ranked fourth after reaching the semi-finals of Wimbledon last summer and is now down at 22.
She showed impressive resilience here, though, withstanding strong pressure to take the second set and then fighting back in the decider against the top seed and a player regarded as one of the best grass-court exponents.
Konta will hope to build on the positive things in her game in a very tough opening match at the Nature Valley Classic in Birmingham on Tuesday against defending champion Petra Kvitova.
