Britain's Andy Murray missed out on a first ATP Tour semi-final in two years after losing to American Tommy Paul in the Stockholm Open quarter-finals.
Murray, 34, beat top seed Jannik Sinner on Wednesday but could not find the same level against an inspired Paul.
The Scot lost 6-2 3-6 6-3 as Paul, ranked 52nd, set up a last-four meeting with fellow American Frances Tiafoe.
British number two Dan Evans led Tiafoe in their quarter-final earlier on Thursday before losing 1-6 6-1 6-1.
Evans' defeat ended the prospect of an all-British semi-final and Murray was unable to continue the nation's interest in the event.
