Nick Compton and James Hildreth combined to leave Somerset in a healthy position after the opening day of their LV= County Championship clash with Warwickshire at Edgbaston.
Defending the only unbeaten record in Division One, Somerset ended on 237 for three as Compton and Hildreth posted an unbroken stand of 132.
The pair joined up after tea with their side on 105 for three and were both 72 not out at the close on a day when rain meant play did not start until lunch.
Rain also had an impact on the eagerly-awaited Roses match at Headingley.
Yorkshire and Lancashire did not make it out until 4.45pm in Leeds and just 28 overs were possible.
The Red Rose made 87 for two during them, with Paul Horton unbeaten on 48 heading into Monday. Tim Bresnan and Liam Plunkett struck for the home side.
England duo Stuart Broad and Ben Stokes returned from injury as Nottinghamshire met Durham at Trent Bridge.
Stokes took three for 70 for Durham but Broad had less of an impact as he was dismissed for a duck in Nottinghamshire's 377 all out.
Samit Patel and James Taylor contributed greatly to that with a 202-run partnership with the former falling one short of a century and the latter making 88.
Notts had been 29 for three at one stage before the duo's rescue act, with Chris Read adding a valuable 59.
In Division Two, former England spinner Gareth Batty ended with career-best figures of eight for 68 as Surrey bowled Essex out for 228.
Batty ripped through Essex's line-up and further exposed their issues with spin as Tom Westley (95) and Ben Foakes (55) accounted for the bulk of the runs.
Batty's work was somewhat undone, though, as his side ended the day on 55 for three with Monty Panesar amongst the wickets.
Will Gidman and Benny Howell, meanwhile, took two wickets each as Gloucestershire enjoyed the better of the play against Derbyshire.
The match did not get going until after lunch because of the weather but Gloucestershire made the most of the available 71 overs as Derbyshire were reduced to 166 for six at stumps, with Paul Borrington leading the scoring with 42.
Glamorgan dominated Leicestershire in Cardiff, dismissing their visitors for 109 and then reaching 56 for one at a rain-enforced close.
Niall O'Brien and Anthony Ireland top scored with 17 for the dismal Foxes, with Jim Allenby (three for 20), Will Owen (three for 42), Tom Helm (two for nine) and Michael Hogan (two for 30) all impressing.
At Tunbridge Wells, Joe Leach took a maiden five-wicket haul in the Championship to put Worcestershire in charge against Kent.
The 23-year-old ended with five for 36 - comfortably bettering his previous best of four for 73 - as Kent were wrapped up for 258 just before the close.
Kent won the toss and chose to bat but failed to cash in, with Sam Northeast their top scorer with 53.
