Haseeb Hameed led Lancashire’s resistance on the second day of their Specsavers County Championship match against Durham at Chester-le-Street.
Replying to 411, the Red Rose recovered from 21 for two to reach 205 for four from 73 overs after Hameed struck 74.
The 19-year-old’s 181-ball knock ended five overs from the close when he missed an attempted fierce pull off a long-hop from Scott Borthwick and was bowled.
The Bolton-born opener concentrated on dogged defence, but completed his 128-ball half-century with one of several wristy leg-side shots. It gave him his fifth four and he added three more as he gave solid support to Alviro Petersen, who made 61, and Steven Croft.
The largely cloudless skies and a placid pitch combined to blunt an inexperienced Durham attack, in which Graham Onions strove hard to provide the lead.
Lancashire seemed to sense they could prosper after seeing him off and his opening spell either side of lunch read 9-5-9-0.
Both he and James Weighell found some life in the pitch with the new ball and a double strike by the latter, a tall Teessider playing his third first-class game, had Lancashire wobbling.
Karl Brown was drawn into a drive wide of off stump and edged to Ryan Pringle at third slip. Then in Weighell’s next over left-hander Luke Procter pushed forward and nicked a much more difficult chance, which Pringle did well to hold low to his right.
The first bowling change came at 28 for two after 18 overs, but the next 10 set of sixes yielded 44 runs as Petersen showed his class on the way to a 94-ball half-century.
He dominated a stand of 104 with Hameed before stepping across to work Onions behind square and falling lbw.
Croft was off the mark with a bottom edge for four off Onions and remained unbeaten on 31 at the close.
In the morning Paul Collingwood fell short of his twin targets as Lancashire secured maximum bowling points four balls before the 110-over cut-off.
Collingwood, on 85 overnight, was ninth out for 97, but his hopes of a century and full batting points had already gone with his team on 375.
Resuming on 341 for six, Durham lost wickets in the day’s third and fourth overs and had added only one run.
Weighell’s edge to gully completed Tom Bailey’s well-deserved first five-wicket haul in Division One. Carse gave Liam Livingstone his fourth catch at first slip and there was another wicket for Kyle Jarvis when Collingwood sliced a drive and was well held by Brown at gully.
A last-wicket stand of 36 between Barry McCarthy, who drove two sixes off Bailey in his 37, and Onions ended when the Irishman hoisted a catch to long-on in Simon Kerrigan’s first over of the day.
