Adam Shepherd took 11 wickets as Lincolnshire beat Northumberland by 32 runs in the Minor Counties Eastern Division at Swalwell.
Skipper Paul Cook made 90 of Lincs' second innings total of 209 to set Northumberland a target of 155.
Then Shepherd took 7-45 to dismiss the hosts for 122 in their second innings.
Director of cricket Mark Fell told BBC Lincolnshire: "The boys did what we asked and I think we've proved we were the better side over the three days."
Fell added: "Shep's bowled really well and our problem soon will be keeping hold of him, because if he keeps putting in performances like that as a 19-year-old he'll have plenty of counties after him."
Lincs openers Dan Birch (66) and Vikram Atri (47) had put on 115 for the first wicket in their first innings, but a batting collapse then saw seven wickets fall for only 14 runs as they were all out for 160, with Richard Waite taking 5-38 and Michael Craigs 4-42.
In reply, Northumberland made 215 in their first innings with Shepherd taking 4-45, before Craigs took 6-54 in Lincolnshire's second innings to claim a 10-wicket haul for the match.
Lincolnshire drew their opening game of the season with Staffordshire.
