British wildcard Ryan Peniston stunned top-seed Casper Ruud with a 7-6 (4), 7-6 (2) victory on Tuesday to advance to the Queen’s Club Championship round of 16.
Peniston, 26, received his call-up to the grass tournament after reaching the quarterfinal of the Nottingham Open last week, and will face the victor of the clash between Francisco Cerunolo and Pedro Martinez in the next round.
Ruud reached the final of the French Open earlier this month but was defeated by 22-time Grand Slam winner Rafael Nadal.
At the end of two grueling sets, Peniston beat Ruud with his first match point.
“It feels like a dream and its mad, I can’t believe it,” he said.
“I knew it would be a tough ask but you have to think you have a chance to win when you step onto the court. The crowd here are incredible.
“Four or five years ago I was sat watching so it’s incredible.”
Fellow Brit Andy Murray withdrew from Queen’s on Monday due to an abdominal injury.
