Notts reclaim pole position
Nottinghamshire missed out on their fifth win of the season but still returned to the top of Division One after drawing with Lancashire.
After the two sides had agreed to forfeit an innings to open up the possibility of victory, Lancashire declared their first innings closed on 350 for nine, with Kyle Hogg unbeaten on 61.
That left the hosts to chase 351 from 90 overs and after recovering from the loss of two early wickets with half-centuries from James Taylor (67) and Adam Voges (55), a home win looked a possibility.
But the loss of Taylor and Andre Adams in successive balls from Ajmal Shahzad left the tail exposed and Notts captain Chris Read (56 not out) decided to bat out for the draw, with the hosts finishing on 293 for seven.
The result leaves them top of Division One after eight games, a point ahead of Warwickshire, who have a game in hand.
Lancashire began the day on 321 for nine but it quickly became apparent that Read and his opposite number Glen Chapple had agreed to manufacture a run chase as Notts asked Taylor and Michael Lumb to bowl.
Hogg duly passed 50 in the 4.1 overs needed for the visitors to reach 350 and secure a further batting point.
Lancashire immediately declared and Chapple was quickly celebrating his first wicket as Alex Hales edged the fourth ball of the innings to wicketkeeper Gareth Cross.
Chapple found considerable movement through the air in a testing opening spell and when Hogg trapped Riki Wessels lbw in the 12th over, Lancashire had taken an early advantage.
A poor first spell from Shahzad relieved the pressure as Michael Lumb and Samit Patel added 64 in 13 overs before the left-arm spin of Kerrigan had Patel back in the pavilion just before lunch, caught at slip by Paul Horton for 24.
Chapple's second spell after the break accounted for Lumb, lbw for 35, but Taylor and Voges dug in to reach tea on 177 for four, with a further 174 required for victory.
Sensing the possibility of a notable win, Notts showed more attacking intent, with Voges stumped off Kerrigan to end a 99-run fifth wicket partnership.
Read helped Taylor to his first Championship half-century for Notts as the pair brought the target down to double-figures.
However, when Taylor was lbw to Shahzad and Adams fell next ball at long-off the hosts opted for safety, with Lancashire unable to prise out the final three wickets.
