Joost Luiten lost his lead at the Gran Canaria Open on Friday.
The South Hollander was unable to continue his excellent opening round.
Wil Besseling, on the other hand, climbed to second place.
The 35-year-old Luiten made an impression on Thursday by hitting a hole-in-one, but needed 68 strokes (2 under par) for his second round.
He recorded three birdies and one bogey.
With a total score of 131 (9 under par), Luiten dropped to a place outside the top ten.
It is not yet known exactly where he will land, as not all golfers have completed their second round yet.
Besseling started the tournament on the Spanish island well and went round in 63 strokes on the second day.
With a total score of 127 he climbed to the provisional second place.
Only the Dane Thorbjørn Olesen did better with 126 strokes.
Darius van Driel and Lars van Meijel were also in the top twenty of the rankings after the opening day.
They are still working on their second round.
