METZ, March 1 (Ligue 1) - A Babacar Gueye penalty gave bottom-club Metz their second home win in a row, while Caen remain winless in 2008.
Pape Malick Diop gave the home side the lead after 35 minutes, though Caen substitute Issam Jomaa grabbed the equaliser with his first goal for the club 11 minutes from time.
Just four minutes later Gueye was fouled in the area and slotted-in the penalty, but despite the win Metz sit a distant 16 points from Ligue 1 safety.
Gueye forced a good save from Caen goalkeeper Vicent Plante with the game's first chance after 28 minutes, receiving a cross back from Miaralem Pjanic on the left but his header from 12 yards was punched away.
Metz did take the lead seven minutes later, Diop pouncing on the rebound after fellow-Senegalese Gueye hit the post.
Daniel Gygax hit the target after 38 minutes, Cedric Barbosa releasing him at the penalty spot, but the Swiss midfielder's powerful shot was parried well by Plante.
Caen had their first chance with half-time approaching, Yoan Gouffran's header blocked by goalkeeper Christophe Marichez.
Two minutes after the break Pjanic played a clever one-two with Barbosa but the 17-year-old Luxembourger's quickfire shot was well saved by Plante.
Jomaa came off the substitutes' bench with 15 minutes left and within a minute superbly headed a Gouffran cross, but Marichez made the save.
The 33-year-old goalkeeper could not stop Jomaa's similar effort a minute later, receiving the ball from Gouffran 18 yards out and controlling well before scoring left-footed.
Metz managed to regain the lead within five minutes, Gueye sending Plante the wrong way with the penalty, won after a bad tackle from Caen defender Nicolas Seube.
