Berlin: Hamburg SV grabbed a 2-1 victory at bottom-placed Borussia Moenchengladbach on Friday to edge up the table as their opponents sunk deeper into crisis at the start of the Bundesliga's winter break.
Gladbach, who are anchored in last place with ten points from 17 games, twice came close early on with Michael Bradley and a 40-metre Juan Arango lob that sliced just wide of the post.
Hamburg, now in eighth place with 24 points, then took the lead when Eljero Elia slotted in from 12 metres in an explosive start to the second half.
The hosts levelled in the 48th minute when Igor De Camargo met a Bradley cross to head in but Piotr Trochowski fired in a freekick in the 72nd minute to offer Hamburg coach Armin Veh some respite.
The defeat will be a further blow for Gladbach coach Michael Frontzeck.
Leaders Borussia Dortmund, 11 points clear after 16 games, will set a Bundesliga record for most points at the halfway mark if they beat Eintracht Frankfurt.
