Unheralded Daniel Brooks overcame a dreadful start and the toughest conditions of the week to keep his unlikely lead at the Scottish Open on Saturday, after a third round in which Rickie Fowler surged up the leaderboard and Justin Rose fell away.

The 528th-ranked Brooks, who surprisingly took a three-shot lead after the second round, recovered from a double bogey on his first hole to shoot a 1-under 69 and maintain a one-stroke lead on 12-under 198.

Raphael Jacquelin, a Frenchman ranked No. 335, shot 64 for the lowest round of the day and was alone in second place, ahead of Joost Luiten (66), Tommy Fleetwood (67) and Fowler, who eagled the par-5 16th in a 66.

Rose, the defending champion, shot 72 to drop from second to 18th.
