Castleford Tigers maintained their unbeaten start to the Super League season with a 30-22 victory over Warrington Wolves on Friday, a win that sees them sit top of the table.
A 10-minute period midway through the first half proved crucial for Castleford as Jesse-Sene Lefao, Greg Eden, Zak Hardaker and Luke Gale all touched down.
Those 22 points in quick succession proved too much for Warrington as they slipped to a second successive defeat, a far cry from last season when they won their opening seven matches.
Tom Lineham and Andrew Savelio tried to get the Wolves back into contention but further scores from Greg Minikin and Eden ensured another win for the impressive Tigers.
Hot on their heels are Wigan Warriors after a narrow victory over Widnes Vikings in a hastily rearranged clash after bad weather had postponed Thursday's meeting.
That match at the DW Stadium never went ahead and Friday's took place in Widnes, but it was Wigan who came away with a 28-26 win thanks to four tries in the final 20 minutes.
Joe Burgess played a crucial role for the newly crowned world champions, the winger scoring twice and playing in Oliver Gildart as the Warriors finished in style.
Huddersfield Giants also have two wins to their name this season - albeit from three games - after they put a disappointing first 40 minutes behind them to beat Wakefield Trinity 24-16.
Sixteen unanswered second-half points proved decisive for the Giants, while Leeds Rhinos matched that early season record with a second win of their own - Brian McDermott's side easing to a 20-14 triumph over Salford Red Devils.
Meanwhile, newly promoted Leigh Centurions got themselves off the mark in style with a 24-16 win over neighbours St Helens.
Leigh flew out of the blocks and found themselves 18-0 ahead just after the half hour, and they were able to hold on to record a memorable victory over Saints.
