Mansfield Town have completed the signing of Ollie Palmer from non-league outfit Havant & Waterlooville for an undisclosed fee.
The 21-year-old finished as the top scorer in the Conference South last season after netting 25 goals for the Hawks.
"I'll run myself into the ground," Palmer told Mansfield's official website.
"Mansfield have given me the opportunity to perform in the league, which is something I have always dreamt about."
The Nottinghamshire club begin their League Two campaign against Scunthorpe United on Saturday.
