Nathan Buck took five wickets, and Academy duo Aadil Ali and Ben Collins shared a spirited ninth wicket stand worth 65, but Lancashire Second XI recorded a ten-wicket Championship win at Grace Road.
Ali made 53 to go with his first innings score of 43* and Collins chipped in with 13 to ensure an experienced Lancashire side had to bat again.
Day three commenced under relentless sunshine that had been present for the previous two days. Resuming from their overnight 508-7, Lancs were dismissed for 519, adding just 11 runs in four overs this morning for the loss of three wickets.
Alex Davies (35) was first to go, caught smartly by Angus Robson at point off Rob Taylor, who was operating from the Pavilion End. Buck then scattered Wayne White's stumps with the first ball of his second over of the morning having made 164 (199b,15x4,5x6).
County then took the new ball and Buck uprooted Adnan Ghaus's middle stump with the third delivery, Lancashire being dismissed for 519 in 114 overs. That represented a lead of 170 and the only changes to the overnight bowling figures were: Buck 22-5-55-5, Taylor 14-2-63-1.
Leicestershire commenced their second innings at 11.30am, in the hope, no doubt, of keeping all wickets intact at lunch. However, at the interval they had slipped to 65-4.
Karl Turner (0) was bowled by Tom Smith, Angus Robson (17) fell caught at slip by Steven Croft off Gavin Griffiths, Taylor (13) was caught spectacularly at slip by Croft off White, and Tom Wells (20) was trapped leg-before by Oliver Newby. Ben Raine (4) and Ali (13) were the not out batsmen at lunchtime.
Wicket tumbled rapidly after lunch, the next three being taken by leg-spinner McKiernan. Raine (22) was next to go, caught and bowled, Oliver Steele (0) fell lbw and Rob Sayer was was caught at short leg by Liam Livingstone. Buck (0) was then bowled by Ghaus.
County were now 105-8 still needing a further 65 to avoid an innings defeat. Then came a splendid ninth wicket stand between Ali and Collins, their good work ensuring Lancs would have to bat again.
Ali was playing the seamers with confidence, and then dispatched McKiernan for three towering sixes into the Bennett End seats in the space of two overs. The maximums were intermingled with a couple of fours, and Ali reached his 50 from 53 balls (6x4,3x6).
Meanwhile, Collins was swaying and ducking a number of short pitched balls delivered by White, Ghaus, and Newby. Ali was finally dismissed, bowled by Newby, for a battling 58 made from 91 balls, the total now being 170-9.
Grant Hodnett, who opened in the first innings, batted at number 11 because of an injury picked up when taking a slip catch. Hodnett's stay at the crease was brief as Collins (13, 39b) soon followed Ali, this time caught behind by keeper Davies off Newby.
County were dismissed for 171 which meant Lancs needed 2 to win and they knocked off the runs from the second ball of the innings. Ali and Collins, both young players, deserve much credit for the way they batted. Bowling figures returned by Lancs today: Tom Smith 8-1-22-1, Gavin Griffiths 6-0-33-1, White 9-4-11-1, Newby 7.1-3-15-3, Croft 1-0-4-0, Ghaus 10-2-34-1, McKiernan 6-2-41-3.
