Siena remained just two points above the Serie A relegation zone after a 1-0 defeat at home to Catania today. Francesco Lodi scored the only goal of the game from the penalty spot midway through the first period after a handball by Alessandro Gazzi, who also gave away a spot-kick in Sunday\'s 4-1 defeat at Lecce. Catania, who were 16th at kick-off, just one place above Siena, moved up into mid-table and are now nine points above the drop zone.
