|LV= County Championship Division One, Aigburth|
|Close, day two: Lancashire 225 & 55-2 v Nottinghamshire 261|
|Lancashire 4 pts, Nottinghamshire 5 pts|
Veteran bowler Glen Chapple's 4-73 limited Nottinghamshire's reply on day two against Lancashire at Aigburth.
Opener Steven Mullaney (82) helped Notts build after dominating the first day, resuming 156 behind on 69-1.
But he was trapped lbw by Tom Smith (3-44), who also got the key wickets of James Taylor and Samit Patel before Chapple mopped up the tail for 261.
Lancashire lost both openers to Peter Siddle (2-25), but recovered to 55-2 at the close, a lead of just 19.
The hosts owe much to the exploits of player-coach Chapple and Smith, who have brought the game back into the balance after experienced seamer Andre Adams's 4-45 helped Nottinghamshire control day one.
It began brightly for Lancashire, when 40-year-old Chapple had Michael Lumb caught behind off just the fifth ball of the morning for eight.
After getting Mullaney, who was dropped four times, lbw for 133-3, Smith then had Taylor when he played onto his own stumps, before seeing Patel caught by Andre Agathangelou at second slip.
Riki Wessels's aggressive 46 off 67 - disrupted by an early tea because of bad light - kept the visitors ticking over, however after he went at 235-6, they crumbled for just another 26 runs.
And despite losing openers Paul Horton and Agathangelou to Siddle, playing his last match before heading back to Australia, Usman Khuwaja (29) and Ashwell Prince helped Lancashire to the close.
Lancashire player-coach Glenn Chapple:
"I think at the moment, 19 in front, two down, with them having to bat last on the pitch, I think we'd say we're right in the game.
"The pitch has shown that when the sun's out it plays really well and when there's some cloud around, it's a bit more difficult for batting.
"It's going to be an exciting game, there's no doubt about that."
Nottinghamshire's Steven Mullaney:
"It wasn't my most fluent innings by any means, but it's not my fault I got dropped.
"I just tried to make the most of it and luckily today I made them pay and got 82. It would have been nice to get a hundred but coming back and doing well against your former county is always nice.
"I've done alright here and it's a ground I've always enjoyed playing at. You get rewarded if you play well and there's rewards for you as a bowler.
"I was open and said it when I left in 2010 that I only left for opportunity. I loved it when I played at Lancashire but there was an opportunity at Notts that I couldn't really turn down."
BBC Radio Lancashire's Scott Read:
"Lancashire have bowled themselves back into the game thanks to a blistering spell from Glen Chapple.
"He took 4-9 from 22 balls after tea, restricting Notts to a lead of 36 when something nearer 100 might have been possible.
"Batting last at Aigburth will not be easy and a target of anything above 200 could be tricky."
BBC Radio Nottingham's Robin Chipperfield:
"Notts will hope they do not regret a first-innings collapse at the end of this game. Being level with Lancashire, and only having five wickets down, it looked as though Chris Read's side might establish a three-figure lead, especially as the captain and Riki Wessels looked in little trouble.
"But the new ball, and a superb spell of bowling from Glenn Chapple, hustled them out.
"It was vital that Notts struck early with the ball, and Peter Siddle - who opened from the River End, rather than the Pavilion End as he had in the first innings - removed both openers in a brilliant spell.
"A chase of 250 might prove tricky at Aigburth, but this is the sort of game that separates title challengers from the rest."
