Power seven shots off Byron Nelson leader Munoz

Seamus Power carded a third round 69 at the AT&T Byron Nelson in Texas that sees the Waterford man seven shots adrift of leader Sebastian Munoz.

Power managed to hit just seven of 14 fairways, and a bogey at the fourth was followed by successive birdies.

Level par on the back nine coming into the last, he saved his best at the par-5 18th where a 304-yard drive and a sublime approach shot led to an eagle to move to 14-under par.

Munoz remains out in front after a 6-under round of 66 and leads the field by one stroke, with Jordan Spieth his closest pursuer after the American shot an 8-under round of 64 to finish on 20-under thru 54 holes.

Joaquin Niemann is a shot further back after a 65, but the round of the day belonged to America's James Hahn who had an 11-under round of 61.
