Redfearn's last season with Oldham constituted a career highlight as he was an ever-present in the team that won the Second Division title and returned the Latics to the top-flight of English football after a gap of 68 years. Redfearn converted the injury time penalty kick in the final game of the season against Sheffield Wednesday that completed a 3–2 victory (after Oldham had trailed 2–0), and snatched the championship from West Ham United, who had prematurely been handed the trophy some 15 minutes earlier. Despite his contribution to Oldham's promotion, he became surplus to requirements with the re-signing of former club captain Mike Milligan from Everton in the off-season and Redfearn was transferred without playing for Oldham in the top flight.
