 A pair of first-half tries from Jonny May made it two Six Nations wins from two for England as they stretched their unbeaten home run to 15 games.In wintry conditions at Twickenham May's predatory finishing combined with resolute defence and a canny kicking game held Wales at arm's length despite a tense finale.Wales kept Eddie Jones' men scoreless in the second half as they clawed their way back into the game and Gareth Anscombe's late penalty put them within a converted try of the hosts, but handling errors and debatable decisions at key moments hurt their chances.
