Both Betfred Super League sides progressed in the early kick-offs, however, it was far from straightforward.
The opening game of the day saw Castleford travel to Doncaster. Ryan Carr's side kept the Dons scoreless in their 14-0 success.
Joe Stimson opened the scoring just after the 20 minute mark. Tom Weaver added the extras, which was the only other points of the half.
In the second half, Blake Taafe crossed for the Tigers' second with Weaver on target again. Weaver kept his 100% record with a penalty later in the contest.
Brad Arthur's Rhinos survived a scare away at Widnes Vikings.
The visitors took the lead through George Brown, however, Mike Butt hit back to level the scores at 6-6.
Brodie Croft was caught high and Leeds opted to go back ahead through a penalty. This was followed by back to back tries from Danny Levi and Brown, as the Rhinos went in to the break with a 18-6 lead.
Butt gave Widnes hope with his second, however, the try of the match sealed the result for the Rhinos. Riley Lumb skipped past the Widnes defence to put themselves 12 points ahead, before Croft added a drop-goal in the 25-12 win.
