Kyle Edmund suffered a straight-sets defeat to Roger Federer in their last-16 match at the Indian Wells Masters.
Federer, who was playing the British number one for the first time, won 6-1 6-4 in one hour and four minutes.
Edmund's nervousness against the 20-times grand slam champion was evident when he started his first service game with two double faults.
He was 5-0 down in the first set before he won a game, but Federer comfortably closed the set out.
The second set was a closer affair, but Federer broke in the fifth game after a forehand winner down the line set up two break points.
The 37-year-old Swiss was tested in the final game as Edmund had three break points.
But Federer saved them all and booked his place in a 13th Indian Wells quarter-final when Edmund sent a forehand into the net.
