Japan’s Kei Nishikori has ended French interest at the Gerry Weber Open in Halle as he overpowered Gael Monfils 6-1 3-6 6-3.
The number four seed, who dropped to world number 12 following his first round exit at the French Open, will next play American Steve Johnson or Russia’s Teymuraz Gabashvili for a place in the quarter-finals.
Monfils, who has a poor record on grass, blamed his dislike for the surface on the defeat in just under 90 minutes.
“I’m not good on grass. I give it my best and grit my teeth but it’s not natural for me,” said the last Frenchman to be eliminated from the German-hosted tournament.
“I’m going to see how I wake up tomorrow,” he added, when asked about the rest of the grass court season and a potential withdrawal from Wimbledon.
In other second round matches, Germany’s Philipp Kohlschreiber advanced easily with a 6-2 6-4 victory over Frenchman Pierre-Hugues Herbert while Colombian Alejandro Falla knocked out Dutchman Robin Hasse 7-6 (7/1) 6-4.
Kohlschreiber, the 2011 Halle champion who has won four of his five ATP titles in Germany, could play world number one and recently crowned French Open champion Rafael Nadal or Germany’s Dustin Brown in the quarter-finals.
There was an upset when Canadian third seed Milos Raonic was bundled out 6-4 6-4 against German wildcard Peter Gojowczyk, ranked 120 in the world.
Raonic reached the quarter-finals at Roland Garros before losing to Novak Djokovic.
Nadal, who has a 50-13 winning record on grass and won Wimbledon in 2008 and 2010, has never been past the quarter-finals at the Gerry Weber Open as he gears up for his third attempt at a tournament dominated by Roger Federer.
The Swiss 17-time Grand Slam winner, is chasing his seventh title at Halle and reached the doubles’ quarter-finals on Wednesday with compatriot Marco Chiudinelli, courtesy of a walkover over German Martin Emmrich and Italian Andreas Seppi.
He takes on Portugal’s Joao Sousa, ranked world number 47, on Thursday in his first singles’ match.
