Frenchman Sebastien Grosjean reached the quarter-finals of the men's singles at Wimbledon on Tuesday, beating Spain's French Open champion Juan Carlos Ferrero 6-2, 4-6, 7-6 (7/2), 7-6 (7/3).
The 25-year-old 13th seed, into the last eight here for the first time in five visits, now meets British tenth seed Tim Henman, whom he beat in a warm-up event at Queen's, in Wednesday's quarters.
Henman has won three of their five meetings to date, including a third-round encounter here four years ago but the Queen's semi-final reverse will give the home favourite plenty of food for thought.
Grosjean, twice a Grand Slam semi-finalist, aced his way to victory after 3hr 07min on the first of three match points in the fourth set tiebreak to deny Ferrero, who was seeded three here.
Claycourt specialist Ferrero, only just coming to terms with playing on grass, missed his chance when, having been two sets to one down on Monday night and the match was halted for fading light, he broke for a 3-1 lead in the fourth only swiftly to drop his own serve.
Grosjean had two break points on the Ferrero serve at 4-4 but two Spanish forehands saved the 23-year-old wiry Iberian nicknamed Mosquito.
The Frenchman, who missed last year's svent with a thigh injury, then held for 5-5 and a break in the 11th game left him serving for the match.
That proved beyond him, however, as Grosjean netted to hand Ferrero a break point before a poor attempt at a drop shot handed the latter a rebreak to force the tiebreaker.
A two-handed backhand and then two serves put Grosjean into the driving seat at 5-2 and a powerful forehand gave him three match points at 6-3.
An ace was a swift coup de grace.
Grosjean, nine wins in his last 11 outings and with three Tour titles to his credit, now hopes to reach his third Grand Slam semi-final after the 2001 Australian and French Opens.
This season he was a quarter-finalist at the Australian Open.
