There are wins built on control and there are wins built on resistance. This appears to have been the second type.
For promotion-chasing sides, that matters. The Championship is relentless, and teams that stay in the race usually collect points in different ways.
The headline moment belonged to Heggebo, whose goal reportedly settled the contest.
It may not have been a polished attacking display, but decisive finishing counts just as much as style.
For Derby, the frustration will be obvious. Playing against 10 men for so long and still coming away empty-handed is the kind of setback that can linger. For West Brom, though, this reportedly felt like a result built on resilience as much as quality.
The next question is whether they can carry that edge into the next fixture. In the Championship, momentum can swing quickly - and wins like this are often the ones teams look back on when the table starts to take shape.
