Ernests Gulbis followed up his victory over Roger Federer by dumping out Tomas Berdych to set up a French Open semi-final against Novak Djokovic.
Far from suffering a let down after the biggest win of his career, Gulbis came out and played even better, thumping sixth seed Berdych 6-3 6-2 6-4.
The Latvian was playing in his first grand slam quarter-final for six years and will now meet second seed Djokovic in his maiden semi-final.
Even if he loses that, Gulbis will be close to a top-10 spot in the rankings when they are updated on Monday.
The 25-year-old, whose love of a good time had looked like it would stop him reaching his potential, joked he would go out and celebrate given he has two days until he plays the semi-final.
Djokovic was also a straight-sets winner, although he had to work hard in the first two sets to break down big-serving Canadian Milos Raonic.
The pair had played a very close match in Rome just before the French Open, with Raonic winning the first set before losing in three.
This time Djokovic, who is chasing a first French Open title, had the edge in the tight moments and came through to win 7-5 7-6 (7/5) 6-4.
Raonic saved a set point at 4-5 in the first but could not save a second two games later, a dipping backhand pass forcing the Canadian to volley wide.
There were no break points at all in the second set but the tie-break went the way of Djokovic, who claimed the crucial mini-break to lead 6-4.
With that the Canadian's hopes appeared to have gone and Djokovic raced into a 5-1 lead in the third.
Raonic mounted a mini comeback with a first break of the Djokovic serve in the match but the Serbian snuffed it out to book his spot in a fourth consecutive French Open semi-final.
