Ireland's Paul Dunne remained the leading amateur at the 144th Open after the second round finally drew to a close at St Andrews.
The 22-year-old from Greystones shot 69 on Friday to reach six under at the halfway stage, two ahead of American Jordan Niebrugge in the race for the Silver Medal, and - impressively - tied for 10th overall.
Dunne's lead might have been cut by Frenchman Romaine Langasque, who was four under with five holes remaining when play was suspended on Friday, but he dropped back to three under after carding a 72.
The only other amateur still to finish his second round on Saturday was former Tranmere Rovers trainee Paul Kinnear, but he failed to make the cut.
The 21-year-old, who had been six under after 11 holes on Thursday, fell away further from his overnight position of level par to finish two over and sign for a 76.
Two other amateurs in with a chance of winning the Silver Medal over the final two days were Shrewsbury's Ashley Chesters and American Oliver Schniederjans, one under and two under respectively.
