Siem sets up another upset

A day of some spectacular scoring in the Wales Open at Celtic Manor - so different to the second round - ended with German Marcel Siem on track to become the third successive shock winner of the title.

Twelve months after world number 377 Jeppe Huldahl triumphed and two years after it was number 164 Scott Strange, the game's 294th-ranked player had a bogey-free 66 to reach 11-under-par.
