YORK'S Simon Dyson fired a scintillating third round 65 to shoot up the Wales Open leaderboard into fourth place.

The 32-year-old ended the day six under par for the round and seven under par for the tournament at Celtic Manor.

He heads into Sunday's final round four shots behind the leader, Germany's Marcel Siem.

Dyson bagged seven birdies and his only blemish was a dropped shot on the par four 12th hole.
