England batsman Zak Crawley's struggles continued as he fell for just 15 in Kent's County Championship match against Derbyshire. Despite this, Kent are well-placed after bowling out their opponents for 304, thanks to Keith Dudgeon's four-wicket haul.
Emilio Gay, meanwhile, enhanced his Test prospects with an unbeaten 75 for Durham against Middlesex. Ollie Pope will aim to boost his own England chances on Sunday as Surrey seek a significant first-innings lead over Sussex, with Pope not out on 14 and Dominic Sibley unbeaten on 116.
Other notable performances include Olly Stone's five-wicket haul for Nottinghamshire against Leicestershire, Kiran Carlson's double century for Glamorgan against Hampshire, and Ricardo Vasconcelos' century for Northamptonshire against Worcestershire.
