Brisbane's impregnable second half defence saved them again as they came from behind to beat Penrith 18-10 at Suncorp Stadium on Friday night and climb to the top of the NRL rugby league table.
For the third week in a row, Brisbane refused to concede a second-half try to their opponents, outscoring Penrith 12-0 after trailing 10-6 at the break.
It was the same story in their previous two wins against Canberra and the Titans, letting in just two points in their last 120 second-half minutes.
Penrith showed considerable more fight than their meek effort against Cronulla last week, but fell short of the upset victory.
