[citation needed] Soon after this, and hours before the midnight, 1 February 1929 cut-off time for players to be registered for the Rugby League Cup, Askin was transferred to Leeds.
[9][10][11] Although he had recovered from a leg injury,[a] the 12-stone, 22-year-old Askin had not played for Featherstone for a few weeks due to a disagreement with the club's board, and they now felt that they had no option but to list him.
Although signed by Leeds to strengthen their left wing, he returned to his more familiar position in the centre for the 1929–30 season and scored 15 tries before being put on the transfer market with an asking price of £500.
He played on the wing and scored a try in Castleford's 11-8 victory over Huddersfield in the 1935 Challenge Cup final at Wembley Stadium, London, on 4 May 1935, in front of a crowd of 39,000.
[26] In March 1937, an exchange deal between Castleford and Newcastle saw Askin move to North East England while G. L. Taylor travelled in the opposite direction.
[27] Newcastle were at that time attempting to establish the sport in the Tyneside region and the Yorkshire Evening Post commented that his loyalty and experience could be of much benefit in that regard.
[32] In September 1930, he played once more for Yorkshire against Cumberland at Whitehaven when George Whittaker of Swinton was moved from the wing to cover for the injured Castleford international Arthur Atkinson, thus opening up a spot for Askin.
