Arjun Atwal's poor run continued as he carded a five-over 77 in the second round of the Valero Texas Open to miss the cut, his 10th in the last 11 starts, here.
His two-round aggregate read nine-over 153.
Atwal had five bogeys and no birdies and through the two rounds he had just one birdie in the first round.
Ben Curtis, the 2003 British Open champion, who has not won on the PGA Tour since 2006, leads the field after 36 holes. His second round of 67 put him at 10-under and two clear of David Mathis and three ahead of Cameron Tringale (65) and Matt Every, who is yet to complete his second round.
Curtis finished his second round just before a two-hour storm delay. A lot of players were yet to complete the second round, which will be completed on Saturday.
