The 4-6, 5-7 defeat at the Dubai Duty Free Tennis Stadium means the 27-year-old Greek, who left the court with his head bowed, will drop outside the world top 40 for the first time in almost eight years.

The first-round meeting between the two unseeded Dubai champions caught the eye as soon as the main draw took place on Saturday for this week’s ATP 500 tournament. Only seven world ranking places separated the pair and the lower-ranked Humbert, at No. 37, edged the pre-match head-to-head record at 3-1. Tsitsipas has not yet progressed beyond the quarterfinals across five events since the start of the year.

“It was a funny first round — the two last winners of the tournament,” said Humbert, who beat Alexander Bublik in the final here two years ago. “It’s so good to be back where I won the tournament. I have such good memories, and it was a tough battle tonight.”
