Italy held Dirk Nowitzki in check but couldn't have expected Johannes Herber to score 10 of his 15 points in the third quarter and lead Germany to a 67-58 victory as the 2005 silver medallists advanced to the 2007 EuroBasket quarter-finals.
Nowitzki had just 15 points - well under his average of 26 points - and 10 rebounds, but Germany received plenty of support from their bench players, who tallied 29 points.
A place in the quarter-finals of EuroBasket 2007 - and possible qualification for the 2008 Olympics - rests in the balance today as Germany and Italy face off in Group F.
The winners will reach the last eight while the losers are left to contemplate what happened along the way, meaning that either the 2005 silver medallists Germany or 2003 bronze medallists Italy will book their flights home.
Hedo Turkoglu poured in a game-high 34 points for Turkey but it wasn't enough to upset Marco Belinelli and Italy on Monday.
Belinelli scored all 17 of his points after half-time as the Italians won 84-75 in overtime.
Italy and Turkey go into their EuroBasket clash today knowing a win is the only result that will stave off elimination for both sides.
The Italians have been reeling ever since they lost to Slovenia on a last-second three-pointer from Slovenia.
