|LV County Championship Division One, Trent Bridge|
|Close, day two: Nottinghamshire 291-8 v Worcestershire 315|
|Notts 5pts, Worcs 5pts|
Samit Patel missed out on his second ton of the season as Nottinghamshire again failed to stamp their authority on promoted Worcestershire.
Dropped catches by the defending champions allowed the visitors to post 315 in their first innings.
But, despite notable knocks from Patel (81), Adam Voges (61) and Steven Mullaney (53), the match hangs in the balance.
Alan Richardson picked up 4-74 as Notts closed on 291-8, still 24 behind.
Earlier, Andre Adams completed his third five-wicket haul of the campaign to help Notts bowl the visitors out, youngster Matt Pardoe taking his new career-best to 74, while Damien Wright weighed in with 65.
After beginning the day on 253-7, 20-year-old Pardoe extended his eighth-wicket partnership with Wright to 96.
But Pardoe chipped Patel to short midwicket, Wright swiftly followed when was trapped by the slow left-armer's arm ball, and Adams wrapped up the innings when Matt Mason attempted to cut.
Nottinghamshire opener Neil Edwards, making his first Championship appearance since June last year, then began with confidence, hitting five sweetly-timed boundaries to help the hosts to only their second half-century opening stand at home in a year.
But, when he was caught behind after being squared up by a swinging delivery from Richardson for 39, two more wickets then fell in quick succession.
Mark Wagh was bowled by Mason with a ball that left him, before Alex Hales was caught behind off Richardson.
With Notts wobbling on 64-3, Patel and Voges staged a recovery, adding 102 in 22 overs.
Both batsmen rode their luck at times, with a number of edges missing the slip cordon, but it still came as a surprise when Voges was plumb to Richardson.
And a late burst of wickets swung the momentum back in Worcestershire's favour.
Gareth Andrew picked up two wickets in two balls in removing Steven Mullaney lbw for 53 and Notts skipper Chris Read caught behind, while Patel undid all his good work by coming down the wicket to the part-time spin of Moeen Ali, miscuing a drive to deep midwicket.
CLOSE OF PLAY SUMMARY
BBC Radio Nottingham cricket correspondent Dave Bracegirdle:
"Once again cricket showed how cruel a game it can be when Samit Patel threw away the opportunity of a ton.
"He had batted faultlessly for three and a half hours and moved effortlessly to a patient 81 when his eyes lit up at the introduction of Moeen Ali into the attack.
"Unable to resist, he danced down the track and perished to his first ill-judged shot of the day. His departure signalled the end of Notts' realistic hopes of a huge first innings total."
BBC Hereford & Worcester's Dave Bradley:
"Good efforts from Pardoe and Wright to get Worcestershire past 300, but Adams was again the best bowler for Notts and thoroughly deserved his "five-for".
"General thinking was that 300 was a par score, as the pitch looked to have flattened out a little, although there were a few that kept low from the Ratcliffe Road end.
"Patel continues to look a class act with a very controlled innings until he played a poor shot to get out in a rare over of spin, but he looks a lot fitter and could revive his international career."
