Yorkshire fought back strongly on the second day of their LV= County Championship match against Nottinghamshire at Trent Bridge.
The defending champions reached the close on 226 for three, with Alex Lees having made exactly 100 in response to the hosts' first-innings total of 428.
Lees scored his century - the seventh of his career - from 223 balls, having hit 11 fours but he fell to the next delivery he faced, edging Will Gidman behind.
The bowler enthusiastically celebrated his first wicket for Nottinghamshire, while wicketkeeper Chris Read also reached a milestone in collecting his 850th first-class dismissal for the county.
Tim Ambrose's bullish century underpinned a Warwickshire fightback after Hampshire's seam bowlers had put their side in control at Edgbaston.
When Warwickshire, collectively guilty of fallible judgement outside off-stump, declined to 120 for six in reply to 319, they were far from certain to avoid the follow-on.
But Ambrose took a faltering innings by the scruff of the neck and forced it forward again as his 113 (159 balls, 17 fours) lifted the hosts to 280 and kept them in an intriguing contest.
In a match in which few batsmen have looked entirely comfortable, though there is nothing wrong with the pitch, a first-innings lead of 39 for Hampshire could still prove very useful.
Richard Oliver's (101) second first-class hundred and aggressive half-centuries from Alexi Kervezee and Gareth Andrew led an impressive Worcestershire response against Sussex at Hove.
Replying to Sussex's 345, the visitors were bowled out for 389 and the hosts reached eight for no wickets in three overs before stumps, still trailing by 36 runs.
In Division Two, Surrey batsman Steven Davies completed the first double century of his career as Kevin Pietersen spent his day in Cardiff combining a spot of fielding with a bit of tweeting.
Having been dismissed for 19 on the first day of Surrey's fixture against Glamorgan, Pietersen was confined to a watching brief as his side kicked on from their commanding overnight position to declare on 563 for seven before the hosts reached 124 for two in reply to trail by 439.
Pietersen had woken up to newspaper headlines from former Australia captain Steve Waugh who suggested that England should move on from the 34-year-old batsman.
Waugh argued that Pietersen brings too much baggage to the England set-up and indeed no longer merits a place in the side, saying Alastair Cook's side "have got to make a clean break and look forward to the future".
But Pietersen took the criticism on the chin and was quick to turn a negative headline into a positive when he responded to the article on social media.
Pietersen wrote on his official Twitter account: "I grew up idolising guys like Steve Waugh, so for him to be even commenting on my situation is quite flattering. He's a legend! Love him!"
Essex launched a fine recovery to leave themselves slight favourites to beat Kent at Chelmsford.
After being left a target of 193, they reached the close on 66 for three, a position of promise that seemed highly unlikely after they had resumed the second day on 67 for six in reply to their opponents' first-innings total of 193.
While Derbyshire's pace attack delivered a late twist to another enthralling day to give the home side a slender advantage against Lancashire.
Mark Footitt and Tom Taylor dismissed openers Paul Horton and Luis Reece along with nightwatchman Peter Siddle as the visitors closed on 36 for three in their second innings - a lead of only 55 with two days remaining.
