Arjun Atwal, the first round co-leader, dropped further down the leaderboard to tied 20th at the end of the third round of the AT&T National golf. The Indian carded a one-over 71, which saw him at one-under for the three days.
Justin Rose, winner of the Memorial last month, had run up a four-shot lead at the top after his third round three-under 67 on Saturday.
He was at 10-under 200 - the only player to reach double digits under par all week on an Aronimink course that is among the toughest PGA TOUR layouts. Rose was four shots ahead of Carl Pettersson, who had a 65, and Charlie Wi, who had a 70. Atwal was one-under 209.
Atwal's fall was largely due to his inability to find the greens as often as he did on the first day, when he shot a 66. From hitting 78 per cent of greens Thursday he dropped to 56 per cent the last two days.
Atwal had just one birdie and two bogeys in his third round.
He birdied the seventh, but dropped after that on eighth. Another bogey came his way on 11th. Tiger Woods shot an even-par 70. He is three-over 213.
Randhawa tied fourth at French Open
Versailles: Jyoti Randhawa stayed in contention at the Open De France with a one-under 70 for a tied fourth place and two shots off the lead at the end of the third round on Saturday.
Of the other Indians, Jeev Milkha Singh shot 68 as he moved up to tied 26th at two-under 211. Shiv Kapur shot a third round 75 and was tied 72nd at five-over 218. SSP Chowrasia had missed the cut.
