Golf: Adam Scott and Matt Jones in contention after third round of the Memorial

Jones shot a 2-under-par 70 to be sharing fourth place at 5-under for the tournament, three shots off leader Matt Kuchar.

Scott is a stroke behind Jones, having posted a 3-under 69 in his third round.

Kuchar produced a 2-under 70 to seize a two-stroke lead over fellow Americans Kevin Chappell and Kyle Stanley.

In a round where world number one Tiger Woods struggled to a 79 to stand 16 strokes off the pace and second-ranked Rory McIlroy settled for a 75 and stood 14 strokes back, Kuchar offset back-nine stumbles with long birdie putts.

Kuchar birdied the par-three fourth hole and the par-five seventh but closed the front nine with a bogey.

He responded with a 19-foot birdie putt at the par-four 10th hole, then sandwiched two birdies between bogeys at the par-three 12th and par-five 15th.

Kuchar dropped an 11-foot birdie at the par-4 13th hole and followed by sinking a 17-foot birdie putt at the par-four 14th at the Muirfield Village lay-out where 18-time major winner Jack Nicklaus is the tournament host.
