Somerset surged ahead with Peter Trego’s unbeaten 154 in Division One while Tom Westley’s maiden double hundred gave Northamptonshire a commanding lead in Division Two by the end of the second day.
Elsewhere in Northampton, Rob Keogh took a remarkable nine-wicket haul while Ben Duckett smashed a blistering 185, putting Northamptonshire firmly on a course for victory against Glamorgan.
Starting on the overnight score of 129 for two, Nottinghamshire lost Michael Lumb (82) and Brendan Taylor (5) early in the first session. An 82-run fifth wicket stand between Jake Libby (144 not out) and Samit Patel (37) rescued the innings for Nottinghamshire.
With the fall of Patel’s wicket, Nottinghamshire lost batsmen at regular intervals. However, Libby completed his ton and pushed Nottinghamshire to 313 runs in 94.2 overs before being the last man to be dismissed.
In their second innings, Durham openers Mark Stoneman (39) and Keaton Jennings (34 not out) added 67. But three quick strikes left Durham at 83 for three at stumps on day two, trailing Nottinghamshire by just 14 runs.
Yorkshire started day two on 275 for nine and added just six more runs in just over three overs before being bowled out.
Hampshire were kept from getting a steady start as Yorkshire pegged away at the wickets column in the early part of the innings. However, James Vince (60) and Sean Ervine (80) came to the rescue with a 107-run stand for the fourth wicket.
Vince fell a little while after his fifty while Ervine added 54 runs with Ryan McLaren (26). Once the partnership was broken, Jack Brooks (5-53) cleaned up the tail as Hampshire were bowled out for 222 runs in 64.2 overs.
In the 23 overs they faced in the second innings, Yorkshire scored 69 runs for the loss of Alex Lees (12) and stretched their lead to 128 runs.
Somerset resumed the innings on the overnight score of 339 for seven. Peter Trego (154 not out) and Ryan Davies (86) shared an unprecedented 236-run stand for the eighth wicket and scored at a brisk pace.
Trego completed his ton and eventually crossed the 150-run mark while Davies also notched his fifty. Soon after Davies’ wicket, Somerset declared on 553 for eight after playing 138 overs.
After a promising 87-run opening stand, Lancashire lost both the openers Haseeb Hameed (56) and Rob Jones (34) in quick succession and were restricted to 138 for two in 52 overs at stumps on day two. They still trail Lancashire by 415 runs with eight wickets in hand.
Starting the day on the overnight score of 1 for naught, Warwickshire lost two early wickets in Varun Chopra (14) and Jonathan Trott (4). A 73-run third wicket stand between Ian Westwood (81) and Ian Bell (19) staged a rescue effort.
However, with the score at 122, Westwood was run out and this led to a batting collapse as Ollie Rainer (5-49) cleaned up the lower order with a five wicket haul to bowl Warwickshire for 172 runs in 74.5 overs.
From the 22 overs they faced in the second innings, Middlesex openers were steady and scored 63 for naught, extending their lead to 133 runs at stumps on day two.
Gloucestershire started the day at 27 for one. Will Tavare (11), George Hankins (34) and Hamish Marshall (11) fell at regular intervals and failed to convert their starts. The innings was rescued by Chris Dent (94) and Phil Mustard (107 not out), who shared 85 runs for the fifth wicket.
After Dent was dismissed close to his hundred, Mustard got together with Jack Taylor (36) and brought up his first first-class century in over five years. However, after Taylor’s wicket, Gloucestershire were rattled by Tony Palladino’s (5-74) five-fer and were bowled out for 331 runs.
Derbyshire lost both the openers inside six overs and were restricted to 16 for two at stumps on day two, trailing Gloucestershire by 73 runs.
Essex resumed on the overnight score of 111 for one. Alastair Cook (66) completed his fifty but was soon dismissed in the 40th over, ending the 153-run stand for the second wicket. Westley (238 not out) and Ravi Bopara (99) turned the game on its head with a 213-run partnership for the third wicket.
Bopara fell agonisingly close to his century and Dan Lawrence (1) soon followed him into the pavilion.
Westley stood solid at the other end, brought up his maiden first-class double hundred and put on an unbeaten stand of 144 runs with Ryan ten Doeschate (77 not out) as Essex stretched their lead to 282 runs at stumps on day two.
Resuming on the overnight score of 23 for naught, Glamorgan were rattled by Keogh’s (9-52) nin- wicket haul and only managed to score 124 runs before being bowled out in 42.5 overs.
In their second innings, Northamptonshire openers Duckett (185) and Rob Newton (25) shared a 113-run opening stand. Duckett smashed the bowlers to all parts of the park and brought up his hundred.
By the time Duckett was dismissed, he smashed 25 fours and three sixes in his 159-ball knock.
Northamptonshire eventually declared after scoring 305 for seven in 58.4 overs, setting Glamorgan a target of 451 runs.
Glamorgan openers negotiated three overs safely without scoring any run to end the second day.
Kent resumed the second day with the score at 211 for five. Darren Stevens (79) and Will Gidman (99 not out) shared a 100-run stand for the sixth wicket.
Stevens was dismissed in the 80th over. Gidman batted well with the lower order and received excellent support from Matt Coles (70). However, Gidman was stranded on 99 runs as Kent were bowled out for 496 runs in 132.5 overs.
After a steady start to the innings, Tom Haines (11) and Ajmal Shehzad (3) fell in quick succession as Sussex ended the second day with the score reading 42 for two after 13.4 overs and a deficit of 274 runs.
