Joey Evison’s seven wickets inspired the Seconds to an innings victory to end their Championship on a high.
The 19-year-old conceded just 25 runs from his 17 overs across days two and three as Leicestershire were bowled out for 190 second time around, the Green and Golds winning by an innings and 57 runs.
Resuming on 152-1 on the second morning, trailing by just nine, Matthew Montgomery (59) and Evison (51) both brought up their half-centuries before falling to Gavin Griffiths.
Sol Budinger fell for five shortly after and, with the score on 170-4, a lead of just nine, Leicestershire had an opening.
Calvin Harrison and Dane Schadendorf quickly shut that door, putting on 99 for the fifth wicket before the former fell for 45, bowled by Abi Sakande.
Schadendorf (63) became the third visiting batsman to pass the half-century mark, quickly followed by the free-scoring Matt Carter, whose 68 came from just 47 balls, including five maximums.
Sammy King (40*) capitalised on a weary Leicestershire bowling attack to lift the score beyond 400, Nottinghamshire eventually all out for 408, a first innings lead of 247.
In reply, the home top order fared slightly better than in their first innings, advancing to 40-1 and 70-2 as they looked to see out the second day.
Evison had other ideas however, carving through the Leicestershire middle order in an eight over spell which yielded figures of 5-18.
The young all-rounder wasn’t done there either, continuing where he left off on the third morning as Leicestershire failed to make Notts bat for a second time.
Combining with Pettman (2-60), the pair worked their way through the hosts’ lower order as no batsmen managed more than 30 in their second innings.
Ultimately it was left to Harrison to secure the victory, Alex Evans caught and bowled for 26 as Leicestershire were bowled out for 190.
Most of the accolades however should go the way of Evison, whose match figures of 9-49 and first innings fifty helped Notts end their season on a high.
