Pyke started commentating on sports back in 1984, when he joined Piccadilly Radio in Manchester, after a four-year grounding on local newspapers. He commentated on Oldham Athletic's football matches during their most successful era, when they reached the League Cup Final and won promotion to the Premier League. During his time at Piccadilly Radio Stuart also commentated on Rugby League matches often combining commentary with programme presentation from the ground he was at.
He then moved on to become the Cricket Correspondent for Independent Radio News, covering England tours to Australia, New Zealand, South Africa and the West Indies. He also covered Rugby League and was the first man to cover a Great Britain Lions Tour for the Independent Radio network in 1988, when Great Britain were in Australia and New Zealand.
In 1998, Pyke moved into television sport and for five years he covered the North West region for Sky Sports News.
