David Bedingham smashed 138 from 99 balls as Durham took a stranglehold on their Vitality County Championship Division One clash with Worcestershire at Kidderminster.
The home side had been bowled out for 184 as Ben Raine, Matthew Potts and Paul Coughlin claimed three wickets each to give the visitors a 60-run first-innings lead.
Bedingham’s knock, which included 13 fours and eight sixes, and 75 from skipper Scott Borthwick helped to increase that advantage to 379 by stumps on day two as the promoted side reached 319 for five.
Bowlers Craig Overton and Migael Pretorius staged a remarkable 139-run partnership to put Somerset in a commanding position against Nottinghamshire.
The pair came together at 314 for eight and remained at the wicket until the South African fell for 77. Overton was then left stranded on 95 when last man Shoaib Bashir was dismissed for a duck with the score on 454.
Nottinghamshire, who made 193 on day one, were 38 for one in their second innings as they reduced the deficit to 223 runs.
Earlier Somerset opener Sean Dickson had added just two to his overnight score of 70 and Tom Banton contributed 83, with Calvin Harrison’s four for 93 the pick of the bowling.
Fletcha Middleton and Nick Gubbins put on an unbeaten 124 for the second wicket as they attempted to drag Hampshire back into touch with Warwickshire at Southampton.
Gubbins had reached 67 and Middleton 61 by stumps with their side 140 for one after the visitors were finally bowled out for 455, thanks in large part to England spinner Liam Dawson’s haul of five for 146 in 40.1 overs.
Rory Burns and Dom Sibley forged an opening stand of 147 as champions Surrey closed to within 59 runs of Kent’s first-innings total on day two at Canterbury.
Sibley will resume on 87 from a total of 185 for one after Tom Lawes and Cameron Steel each took three wickets as the home side were bowled out for 244.
Skipper Tom Westley hit 81 to help Essex take control of their showdown with Lancashire at Chelmsford.
Having resumed on 68 for one in reply to the visitors’ 146, the hosts made 377 with opener Dean Elgar going for 79 and George Balderson taking three for 75, and the Red Rose county finished the day on 10 for one in their second innings, a deficit of 221.
In Division Two, Leicestershire opener Marcus Harris plundered a double-century as Derbyshire were left with a mountain to climb.
Harris’ 214 was the backbone of a mammoth total of 574 for seven declared in which Peter Handscomb and Ben Cox hit 68 and 69 respectively.
The hosts’ response then got off to a dreadful start with Harry Came, Luis Reece, Wayne Madsen and Brooke Guest all falling cheaply as they limped to 54 for four by the close.
Tom Alsop’s 84 and an unbeaten 75 from Cheteshwar Pujara helped Sussex reach 267 for five as they ate into Gloucestershire’s first-innings total of 417.
Danny Lamb and Jack Carson had both taken three wickets as Zafar Gohar’s 60 and 45 not out from Zaman Akhter eased the visitors past 400 at Hove.
Yorkshire face a fight to set a competitive total after a challenging second day against Middlesex at Lord’s.
Having seen the hosts take an 87-run first innings lead thanks to half-centuries from Leus du Plooy and Josh De Caires, they ended the day on 216 for seven in their second – Toby Roland-Jones and Ryan Higgins claiming three wickets each – and will resume 129 ahead.
Ricardo Vasconcelos’ 166 not out left Northamptonshire in a dominant position at Glamorgan.
The hosts were 314 for two at the close, 43 runs ahead with Ben Sanderson having taken five for 92 as the Welsh side, for whom Colin Ingram scored 82, had been dismissed for 271.
