An unbeaten 88 from skipper Matthew Montgomery and a half-century from Freddie McCann guided the Seconds to a six-wicket victory over Lancashire at Lady Bay.
The pair combined for an unbeaten 102-run third wicket stand which broke the back of a tricky chase, after James Hayes had earlier added a five-wicket haul to his first innings three-fer.
At the start of the day, Lancashire resumed on 144/6, a lead of 158.
They had added just six to their overnight total when Hayes struck, before removing the Red Roses’ eighth batter just four runs later.
Harry Singh and Charlie Barnard steadied the ship for the visitors with a 39-run ninth-wicket stand before Hayes returned to remove the latter for 20 his fifth wicket in innings analysis of 5-40.
Singh would progress his score to 60*, and Lancashire total to 209, before the innings was wrapped up, the Green and Golds set 224 for victory.
In pursuit of the highest score in the match, Notts lost Sol Budinger early on, one of three wickets for George Balderson.
Ben Martindale made a brisk 31 before succumbing to the Lancashire seamer, paving the way for Montgomery and McCann’s match-defining partnership to take shape.
Across a 32-over period the duo thwarted the best efforts of the visiting attack, McCann providing a promising display in his first Championship outing for the side.
The left-hander would eventually fall for 51, caught behind off Balderson, before Barnard, who’s lower order runs were crucial earlier on in the day, bowled Dane Schadendorf without scoring.
Despite that late afternoon wobble, the Green and Golds were unperturbed, expertly marshalled to their total by Montgomery and Sammy King (30*), for the loss of just four wickets.
