After winning the toss and bowling first, Kent were taken to the cleaners by Robert Yates (128) and Sam Hain(124*) of Warwickshire, piling on the runs against the hapless bowlers and ending the day on a dominant 367/3.
Ben Brown (95) and Keith Barker (58) put on 96 runs for the 7th wicket, rescuing Hampshire from 114-6 to a total of 256 against Surrey.
David Bedingham of Durham scored 118 to lift his side to 363-7, dominating the day and setting things up for the bowlers on Day 2.
Leicestershire saw three of their top four scoring fifties. While opener Soloman Budinger kickstarted it with a 62-ball 72, it was taken forward skipper Lewis Hill’s 75 and Colin Ackermann’s 79. The duo remained unbeaten, having added 141 out of a score of 243 by Stumps.
Sam Cook picked up 5 wickets for 42 runs to help Essex bowl out Lancashire for 207, getting rid of four top and middle order wickets, giving Essex the upper hand on Day 1 in at the County ground in Chelmsford.
At Trent Bridge, Nottingham, Lewis Gregory picked up 7 wickets for Somerset, as Nottingham collapsed from 125-0 to 256 all-out. After picking up regular top order wickets, Gregory ran through the tail. However, it was counterproductive as Somerset lost two wickets trying to play out until Stumps.
