George Fenwick was one of a number of players signed by Leeds City from the North East. He was recruited by Peacocks manager Herbert Chapman from Shildon Athletic in January 1913 as cover for Fred Croot when the reliable left winger suffered an injury against Bradford Park Avenue. At the time, Fenwick's season had yielded a notable 17 goals for Shildon in the North Eastern League.

The new man was swiftly given his debut, against Chapman's old club Northampton at Elland Road on 1 February. The friendly gave City fans the opportunity to check out the Cobblers' legendary midget, Fanny Walden, but Fenwick stole the honours, scoring twice in a solid victory.

JRB in the Leeds Mercury: 'The fact that Fenwick scored a couple of goals shows that he has strengthened the City left wing. True, the goals were not those which are termed beauties, but the prompt way in which he put the ball into the net when an opportunity presented itself indicates that he is a fine opportunist. He also dribbles well and should make a useful partner for Speirs.'

The display was enough to earn Fenwick his League debut the following week against Leicester Fosse, and again he scored. His display in a 5-1 victory prompted this in the Yorkshire Post: 'Mr Chapman, the manager, is slowly but surely evolving a set of players from whom much may be expected in the future. His latest acquisition is a youth named Fenwick, from Shildon, and although his methods are rather crude at present, he evidently possesses talent capable of being turned to good account under skilful training.'

This enterprising start was followed by a depressing 6-0 defeat at Stockport, but then Fenwick was back, netting a brace in a 5-1 victory at eventual champions Preston.

When Croot returned to fitness, he was recalled and Fenwick dropped down to the reserves. It was a real surprise, however, when Herbert Chapman decided against retaining the youngster's services at the end of the campaign and the winger drifted out of the professional game despite a promising return of three goals from five League appearances.
