Tiger Woods made the cut by one shot but England's Andy Sullivan was only two off the lead at the halfway stage of the Memorial Tournament in Ohio.
A frustrated Woods bogeyed the 16th and 17th and needed to par the last for a 70 to make the cut at one under.
Sullivan, the 29-year-old world number 58 from Nuneaton, who won twice in South Africa this year, had eight birdies in a 64 and reached 10 under.
Swede David Lingmerth leads by one at 12 under after seven birdies in a 65.
Former US PGA Championship winner Jason Dufner is second after a 67 in which he birdied the 14th, eagled the 15th and then made a hole-in-one with a six-iron at the par-three 16th.
Woods, a five-time winner of the event at the Muirfield Village Golf Club, began his round with three birdies in the opening four holes but some wayward tee shots into thick rough led to a number of dropped shots.
At the last he drove left into more thick rough and was just short of the green in two, but a majestic chip finished three feet from the flag and he calmly holed the putt to maintain his record of never missing the cut in 15 Memorial appearances.
Former US Open champion Justin Rose, winner of this title in 2010, is three shots off the pace in a share of fifth after seven birdies in a 67, recovering from a double bogey at the 12th when he found the water at the par three.
Masters champion Jordan Spieth was five under for his first eight holes but finished with a 70 and is six strokes adrift at six under.
Scotsman Russell Knox, who had seven birdies in a first round 64, had only one in a 74 on day two and is eight back on four under.
