Louis Oosthuizen and Brian Davis share the halfway lead at the Houston Open.
The Englishman shot a seven-under 65 to go level with the 2010 British Open champion on 11-under for the tournament.
Play was suspended due to bad light, with Houston resident Jeff Maggert on 10-under par and eight holes of his second round left to play.
Behind him is a group of five, including Phil Mickelson, on nine-under.
Ernie Else, who must win if he is to qualify for the Masters next week, is currently tied for 28th on five-under.
