Kent vs Somerset, Canterbury
Kent and Somerset finally found some game time, and the game moved rapidly as both teams combined to lose 22 wickets on the day, with Somerset eking out a slender lead.
They were first buoyed by a tremendous six-wicket haul from Lewis Gregory, who ran through the middle and lower orders to finish with 6/32. Ollie Robinson was the top scorer with 37. In reply, Somerset were in control thanks to a fine half century from Tom Banton. They were in a good position at 139/5, but the wicket of Banton saw the visitors lose more in a hurry. Gregory came to their rescue once again, with a fighting 26 as Somerset took a handy lead. They were eventually bowled out for 169 - a lead of 30.
Batting for the second time in the day, Kent lost two wickets cheaply to find themselves in deep trouble.
Brief Scores: Kent 139 (Ollie Robinson 37, Lewis Gregory 6-32) & 24/2 trail Somerset 169 (Tom Banton 63, Harry Podmore 3-37, Grant Stewart 3-37) by 6 runs.
Surrey vs Yorkshire, Guildford
Surrey rode on fifties from Mark Stoneman, Ben Foakes and Jamie Smith to end their third day at 290/8.
Batting first, Surrey made a great start before they lost Dean Elgar with the score on 78. A mini collapse saw them lose four wickets for 69 runs and find themselves in trouble. Foakes and Smith, however, shared a much-needed 118-run stand to prop up the innings, but just when Surrey looked good to consolidate on that position, another collapse came calling. This time, they lost four wickets for 20 runs to end the day at a precarious 290/8.
Yorkshire captain Steven Patterson was the best bowler with four wickets, including three in an over that kicked off the second collapse.
Surrey 290/8 (Ben Foakes 62, Mark Stoneman 61, Steven Patterson 4-71) vs Yorkshire.
