Britain’s Cameron Norrie failed to make the final of the Lyon Open after a 6-1 7-6 (8-6) defeat by experienced Frenchman Gilles Simon.
Norrie, 22, had claimed the biggest win of his career by beating world number 10 John Isner in the quarter-finals.
But the world number 102 was beaten in straight sets on the clay-court by 75th-ranked Simon.
Norrie struggled with his serve in the first, but took the second to a tie-break before blowing two set points.
Simon will face top seed Dominic Thiem in the final after the Austrian defeated Serbia’s Dusan Lajovic 6-4 5-7 6-4 in his semi-final.
British number three Norrie is expected to rise up the rankings after a positive week in France, reach a ranking of 85 as he enters the French Open next week.
He had never played a professional match on red clay until he featured in the Davis Cup in February.
But after a first set in which he lost his serve three times, the left-hander fought his way back into the semi-final.
The second set played out without a single break of serve as Norrie matched home favourite Simon, before the match slipped away in the tie-break.
Elsewhere, James Ward is through to the semi-finals of the ATP Challenger Tour in Loughborough after Russia’s Teymuraz Gabashvili retired in the second set with the Briton leading 7-5 5-4.
