The end of round one of the Lyoness Open has left Englishman Tom Lewis at the top of the leaderboard with a nine-under-par 63.

Lewis had a steady start on the first three holes by scoring par, but he was able to clinch four birdies by the end of the front nine, which was followed by a further four birdies before the round was up.

Joost Luiten sits two shots off the lead by carding 65, while Graeme Storm, Alexander Levy, Richard McEvoy and Simon Dyson all sit in joint-third with a six-under-par round.

Miguel Jimenez finished the opening round on five-under 67.
