Watch highlights of Crewe 0 Wolves 2
Watch the match highlights as Wolves' first-team start pre-season with a win at Crewe before heading off on their pre-season tour of Ireland.
First Crewe failed to clear their lines and the ball came back into the box via Joe Mason for Dominic Iorfa to coolly beat goalkeeper Ben Garratt from close range.
Then with just a minute left Mason doubled Wolves' advantage and gave the scoreline a fairer reflection.
Goalkeeper Andy Lonergan's long kick evaded everyone and Mason was clean through, dinking over Garratt with a nice finish that ended the night on a positive note.
