Division One leaders Surrey are closing in on another Specsavers County Championship victory after making Nottinghamshire follow-on at the Oval.
Third-placed Notts ended the second day 83 for two in their second innings having been dismissed for just 101 in their first go.
Surrey batsman Mark Stoneman had earlier completed his first century of the season having been 99 overnight, and reached 144 before being caught behind off Luke Wood as the hosts piled on 375.
Tom Curran then took five for 28 as Notts’ batting line-up failed, but opener Kraigg Brathwaite battled through 100 balls in the second innings to reach stumps 39 not out.
Second-placed Somerset had to deal with a Yorkshire fightback at Headingley.
The visitors quickly lost their last two first-innings wickets to be dismissed for 399 but appeared to be in firm control when they reduced the White Rose to 119 for five.
However, a 173-run stand between Tom Kohler-Cadmore (81) and Andy Hodd (84 not out) brought Yorkshire back into the contest, though Josh Davey (four for 53) struck twice late on to leave the relegation-threatened hosts 292 for seven at stumps.
Fourth-placed Essex reached 363 for six at stumps as their game with Hampshire finally got started on day two at Chelmsford.
After the defending champions won the toss and elected to bat, Dan Lawrence made the most of the conditions to score an unbeaten 114.
Varun Chopra (61), Ryan ten Doeschate (55) and Adam Wheater (52) also cashed in, while Kyle Abbott took three for 58 for the visitors.
Bottom side Lancashire are chasing 314 to beat Worcestershire in their relegation battle at Southport.
The Red Rose were dismissed for 161 before Worcestershire recorded 252 all out in their second go, aided by a half-century from number eight Wayne Parnell.
The hosts were eight without loss at stumps and need a fine batting display on day three as they look to move above their opponents in the table.
Ian Bell continued his impressive campaign as he struck a double hundred to help Division Two leaders Warwickshire build a huge first-innings advantage against Glamorgan at Colwyn Bay.
Warwickshire started the day 116 for three in reply to the hosts’ 203 all out, and they ended it 445 for eight after Bell struck 204 and passed 20,000 first-class runs.
Sam Hain, who hit 62, was the only other Warwickshire batsman to pass 50 but they were able to build a 242-run lead on the back of Bell’s brilliance.
Another discarded England batsman hit form as Dawid Malan hit a half-century to put Middlesex on top in their battle with second-placed Sussex.
Captain Malan, who was dropped after England’s first Test against India this summer, reached stumps on 69 not out to lead his side to 210 for five in their second innings – a lead of 208 after Sussex were bowled out for 171.
Third-placed Kent were struggling to take wickets against Derbyshire after compiling a massive 561 batting first at Derby.
The home side were 210 for two at stumps after Billy Godleman (71) and Wayne Madsen (60no) scored half-centuries against the Kent attack.
Leicestershire, in fourth, were struggling to put the pressure on the top three as they were bowled out for 111 by lowly Gloucestershire at Bristol.
Ryan Higgins took four for 26 as Leicestershire collapsed from 62 for two, before the hosts ended the day on 152 for one in their second innings, giving them a lead of 243.
Elsewhere in the second tier, Northamptonshire recorded a seven-wicket win inside two days against fellow strugglers Durham.
Northants recorded just their second win of the campaign, despite starting the day by losing their last four first-inning wickets for just nine runs, leaving them 198 all out.
Cameron Steel scored 50 for Durham, but they were bowled out for 133 second time around, and Northants reached their target of just 65 in 16.2 overs.
