Kyle Edmund has often shown his best form on clay but the 21-year-old Briton enjoyed the finest win of his career when he beat France's Gilles Simon 6-4, 3-6, 6-1 in the first round of the Aegon Championships.
Edmund, who had won only one of his previous eight tour-level matches on grass, was ultimately a convincing winner over the world No 18, who had won their only previous encounter at Eastbourne in 2013.
Edmund, currently just three places off his career-high position of No 82 in the world rankings, broke into the world's top 100 for the first time last summer and gained direct entry into a Grand Slam tournament for the first time at this year's Australian Open.
He will face another Frenchman in the second round after Paul-Henri Mathieu beat Britain's Dan Evans 7-6, 6-7, 6-3.
That result blocked the prospect of another all-British encounter in the second round today after Andy Murray and Aljaz Bedene secured their first meeting with one another after victories on Tuesday.
Murray believes Ivan Lendl can make an instant impact following his return as coach.
"I expect Ivan to have a positive impact on me and my whole team," Murray said.
"Whether that happens in three days or a few months I have no idea, but I trust and believe in what he says and that can obviously help immediately.
"But, ultimately it's up to me to perform on the court."
Murray has never played Bedene before. He will be the only British opponent the world number two has ever faced on home soil at tour level and the first anywhere since he lost to Tim Henman in Bangkok 10 years ago.
"It's amazing really," Murray said. "I think maybe Tim is the only one that I ever played. I never played Greg (Rusedski) in a competitive match.
"I played Tim a few times but it's been a long wait really."
