Teenager Tom Kohler-Cadmore narrowly missed a maiden first-class century at New Road as Division Two leaders Worcestershire moved closer to a second County Championship win over Leicestershire in a month.
The 19-year-old was bowled by Dan Redfern for 99 after helping Worcestershire to second-innings declaration at 416-8, which set bottom-of-the-table Leicestershire a target of 458.
Greg Smith opened up with eight fours in an unbeaten 38 but a 27th championship game without a victory is the most likely outcome for Leicestershire, with Angus Robson and Ned Eckersley already out as they reached 56-2 in 21 overs by the close. They will require a further 402 runs on the last day.
Michael Carberry's 48 not out guided second-placed Hampshire into a 44-run lead at 83-1 in their second innings at stumps on day three against Essex at Colchester.
Essex had earlier been limited to a first-innings advantage of 39 after collapsing from 187-2 to 285 all out.
Jesse Ryder (79) and Ravi Bopara (69) put on 115 for the third wicket but the middle and lower order subsided quickly thereafter as Hampshire's bowlers shared the wickets around.
Madsen leads the way
At Cheltenham, skipper Wayne Madsen was in the runs as Derbyshire hit back strongly on day two against Gloucestershire.
Having bowled out Gloucestershire for 356 from an overnight position of 304-6, Derbyshire replied with 216-2, Madsen ending the day unbeaten on 79, having faced 147 balls and hit nine fours.
Opener Ben Slater made 70, while Shivnarine Chanderpaul is still there on 50 not out, with his side trailing by 140 at stumps.
Gloucestershire had earlier been indebted to Will Gidman for his second century in successive championship games. Unbeaten on 88 overnight, the all-rounder was last man out for 125, having faced 216 balls and hit 19 fours.
Tom Taylor finished with 5-58, his first five-wicket haul in the championship.
