Britain's Dan Evans was unable to follow up his maiden French Open victory with another win as he was knocked out in the second round.
Evans, seeded 29th, lost 6-3 3-6 6-2 6-3 against Sweden's world number 95 Mikael Ymer on the Paris clay.
Evans trailed 5-1 on the way to losing the first set and, after improving in the second, faded in the final two.
His exit means British men's number one Cameron Norrie is the only player from the nation left in the singles.
US Open champion Emma Raducanu was knocked out in the second round on Wednesday, joining Heather Watson and Harriet Dart in being eliminated at Roland Garros.
