Bjorn Sigurdarson's first goal of the season has put Wolverhampton Wanderers on course to record a third consecutive win in League One.
The Icelandic international's strike is all that separates Wolves and visitors Crawley Town at half time.
Sigurdarson, who had been denied by a strong save from Paul Jones moments earlier, broke the deadlock on seven minutes with a placed header from Kevin Doyle's left-footed cross.
More Doyle industry down the left almost created a second goal on the quarter-hour, but Bakary Sako nodded wide.
Wolves, who had started so brightly, then went off the boil as Crawley began to dominate.
The Sussex outfit should have levelled the scores on 23 minutes, when Gary Alexander set up Joe Walsh, who missed an absolute sitter from six yards.
Wolves goalkeeper Carl Ikeme was then called upon to make an impressive save to deny Nicky Adams.
