London Blitz dropped their first points of the campaign after failing to hang on to an early lead against city rivals London Warriors as they went down 37-10.

The two London rivals provided the anticipated slugfest for the first 30 minutes of Sunday’s league clash – but it was the Warriors who eased clear in the second half and ran out comfortable winners.

A drive that was aided by a series of personal foul penalties on the Warriors enabled Blitz quarterback Josh Adamson to put his side on the scoreboard first with a short touchdown run.

The home side kicked a field goal, only for Luke Naughton to respond in kind for Blitz, but a touchdown pass to Luc Benjamin just before half-time brought Warriors level at 10-10.

That gave the Warriors momentum as they found the end zone twice in the first five minutes of the third quarter to take a decisive 24-10 lead – and there was no way back for the Finsbury Park side.

They failed to fire in the remainder of the game and the home side took advantage, increasing their margin of victory to 27 points.

Blitz will be on the road again on Saturday, when they face South Wales Warriors (2.30pm).
