There are now eight matches ongoing in the Specsavers County Championship and today's action proved something of a mixed bag with bowlers on top in some games, batsmen enjoying themselves in others, and some remaining very finely balanced.
Hampshire dominated proceedings against Lancashire with three players reaching half-centuries to propel them to 276 for one.
Jimmy Adams was the only man to be dismissed when he was caught by Steven Croft off Jordan Clark for 88, having put on 191 with Will Smith for the first wicket.
Smith made it to stumps unbeaten on 99 with Tom Alsop not out on 50.
Jason Roy (110 in 142 balls) and Rory Burns (88 in 127) were not hanging about as they helped Surrey post 384 for eight against Middlesex at Lord's.
The pair put on 118 together for the fourth wicket after Surrey had been reduced to 70 for three. Ben Foakes then added 53 not out as Tim Murtagh, James Harris and James Franklin all took two wickets for the hosts.
Wickets tumbled at Taunton, 17 of them in all, on a day for bowlers. Somerset won the toss and chose to bat only to limp to lunch at 116 for seven and thanks to 42 from Craig Overton, inch their way to 184 before being bowled out in 41.1 overs.
Chris Rushworth and Mark Wood took three wickets while Graham Onions and Paul Coughlin took two apiece.
Durham fared little better in reply, going to tea at 65 for three and losing four more wickets before stumps, which came with them on 154 for seven. Six of those wickets were shared equally between Roelof van der Merwe and Jack Leach.
It was a tight battle throughout day one between reigning champions Yorkshire and Warwickshire. Yorkshire were 62 for two at lunch after a cautious morning which saw them lose Alex Lees (10) and Adam Lyth (24) and while they made good progress in the afternoon, they lost three more wickets and were 172 for five at tea.
Travis Head made 54 but two more wickets in the final session helped Warwickshire fight back although they will be desperate to end a 10th-wicket partnership between Steven Patterson (35 not out) and Ryan Sidebottom (11 not out) that has already put on 48 together.
Kent resumed on 55 without loss after bowling Worcestershire out for 211 on day one, and made good progress all day.
They lunched on 152 for three and half-centuries from Sean Dickson (79), Darren Stevens (81) and Will Gidman (54 not out) helped them move ahead well before stumps.
They were closing in on 400 at the end of the day and already lead by 186 runs.
Having been 38 for four early on day one, Northamptonshire's recovery to be all out for 321 was mighty impressive.
Laurie Evans hit 74, David Murphy 45 and Saif Zaib 65 not out while Rory Kleinveldt belted four fours and seven sixes in a whirlwind 88-ball 91 that rocked Glamorgan, for whom Timm van der Gugten, Lukas Carey and David Lloyd all took three wickets.
Nick Selman then made 79 not out for the home side but wickets fell at the other end - three to Azharullah and two to Ben Sanderson - to leave them struggling at 97 for five before he and Andrew Salter (24 not out) steadied the ship.
A decent day for Essex saw Nick Browne (55), Jaik Mickleburgh (54), Daniel Lawrence (65) and Ryan ten Doeschate (83) all hit half-centuries.
Jofra Archer took three for 74 and Steve Magoffin two for 76 for Sussex but the home side will be happier with their day's work.
Things remain evenly poised at Grace Road, perhaps swinging back towards Leicestershire but only because of Ned Eckersley's 73 not out in 160 balls.
After choosing to bat first, Leicestershire made a good start and were 102 for two at lunch as Paul Horton (42) and Neil Dexter (44) made useful contributions.
Derbyshire fought back as the day wore on, however, Callum Parkinson marking his Championship debut with three wickets as Leicestershire slipped to 206 for six.
Eckersley then put on 83 with Clint McKay (40) for the seventh wicket and steered the home side to 300 when play ended for the day.
