Rhinos went 22-0 down in the opening 31 minutes and, though they improved after that, there was no way back.
It was a tough evening for Leeds who were without captain Kruise Leeming because of illness, but Harry Newman's return from long-term injury was one positive.
Here's how the players rated in Rhinos' 30-16 defeat.
