Motherwell gained their first away win in the league for a year thanks to two goals from teenage striker David Clarkson.
Clarkson struck once in each half to ease the pain Motherwell fans have been feeling since the sale of James McFadden.
Hibs threatened first and a short free-kick from Grant Brebner set up Garry O'Connor but his low 25-yard shot was beaten out by Gordon Marshall.
But Motherwell took control after this and, but for some careless finishing and inspired goalkeeping from Daniel Andersson, would have been well ahead by half-time.
Andersson touched a 16-yard shot from Alex Burns past his post before he had to react smartly to turn a Derek Adams free-kick for a corner.
The goalkeeper made an instinctive save to keep out a Stephen Craigan header before Keith Lasley should have done better than shoot straight at Andersson when he was left unmarked at the far post.
Burns came closest in the 29th minute when a poor header from Colin Murdock gave him a chance but his volley struck the post.
Hibs looked uncomfortable at the back and Adams blasted another effort over from just ten yards with the goal at his mercy.
The goal finally came a minute from the break when Lasley headed a Burns cross against the post before Clarkson bundled the ball home from just a yard out.
Hibs tried to turn the tide in the second half but Motherwell always looked the tidier side.
Stephen Pearson was tame with a finish after a fine run into the area and Clarkson headed over from good position.
The second goal arrived with 15 minutes left when a lazy passback from Yannick Zambernardi let in Clarkson and he prodded the ball past Andersson.
