(CNN) -- Belgian Nicolas Colsaerts holds a two-stroke lead after the opening round of the Dutch KLM Open in Hilversum.
The 27-year-old birdied the final three holes to post an eight-under-par round of 62, his best-ever on the European Tour.
Englishman Kenneth Ferrie and India's Shiv Kapur head the chasing pack after rounds of 64.
Colsaerts, who has yet to win on the European Tour and has spent the last three years on the second-level Challenge Tour, told the official European Tour website: "I am realising again that I can compete at the highest level.
"I am still not happy with the level of my chipping and putting but I am always working on that."
European Ryder Cup player Ross Fisher is among seven players tied for fourth place on 65 (-5).
Fellow Celtic Manor debutant Martin Kaymer -- the US PGA champion -- is also in touch after carding a 67.
