Notts closed on 127-5, a lead of 231 so it looks like a first defeat of the season on the way for a weakened Lancs.
It was a good effort, though, by the medium pacers Bailey (2-46), Lamb (1-46), and Balderson (2-29), and it's the performances of Balderson and the other youngster, Lavelle, that will give Lancs something positive to take from the game even if they lose.
Elsewhere, Yorkshire gave hapless Somerset their second consecutive thrashing, winning by an innings and 33 runs with 9 wickets in the game for Matt Fisher, who I'm sure would have been an England regular by now if not for a terrible succession of injuries. Amazingly, he's still only 23, so there's still hope.
At Edgbaston, Hampshire have a lead of 233 over Warwickshire with 2 wickets left including Lancy lad Keith Barker, 49no, to add to the 5 wickets he took in the Warwick innings.
