Jeev Milkha Singh fired an improved three-under 67 to rise to tied 44th but Arjun Atwal slipped to tied 59th after returning a one-over 71 in the second round of the Byron Nelson Golf Championship.
Jeev's two-day total stands at one-under 139 with Atwal a stroke adrift at a total of 140.
Jeev struck a couple of birdies against a lone bogey in the front nine to make the turn one-under. His backward journey turned out be better as he picked up birdies on the 13th, 15th and 16th holes before dropping a shot on the 17th hole.
Atwal, on the other hand, was left to rue a late slump. The Orlando-based golfer found a lone birdie in the front nine to be one-under at the turn.
On his way back, Atwal picked up back-to-back strokes in the 10th and 11th holes before stumbling to a double bogey on the 14th. Successive bogeys on the 17th and 18th only compounded his woes. At the top of the leader-board, American Cameron Backman (61) and Blake Adams (64) shared the lead at 10-under 130. Australian Jason day (65) followed them a stroke behind at the third spot.
Chowrasia makes cut
Wentworth, England: SSP Chowrasia, down nine rungs to tied 12th with a two-over 73 in the second round, was the lone Indian left in fray after Shiv Kapur and Jyoti Randhawa missed the cut at the BMW PGA Championship here.
Kapur finished with a total of five-over 147 despite turning in an improved three-under 68 in the second round. At the top, England's Luke Donald (68) took the sole lead with a total of six-under 136.
