Read and Onions share honours
Durham 351 and 6 for 0 v Nottinghamshire 261
A superb unbeaten 133 by Nottinghamshire skipper Chris Read was finally upstaged by a six-wicket haul for Graham Onions as County Championship leaders Durham took a first-innings lead of 90 at Chester-le-Street.
Both Onions and Callum Thorp were on a hat-trick at the same time when the visitors' first four wickets all fell on 21. And Onions ended the innings by again taking two wickets in two balls to finish with a season's-best 6 for 95.
Despite a fifth-wicket stand of 178 between Read and Adam Voges, Nottinghamshire were all out for 261, losing all their last four wickets to Onions for 21 runs. Their surprising decision to send in two debutants to open backfired as 18-year-old Sam Kelsall could have been out three times before Onions had him caught behind for 11.
He got off the mark by edging the sixth ball of the innings for 2 via Paul Collingwood's left hand at first slip, then was almost run out twice. When Riki Wessels played back to a good length ball and lost his middle stump Onions had taken wickets with the last two balls of an over. Then off the third and fourth of the next over Thorp had Durham Academy product Karl Turner lbw for nine before Phil
Mustard took a fine catch diving to his right to send Steve Mullaney packing. Read played Thorp's hat-trick ball confidently through mid-wicket for three and scored the first 25 runs in his stand with Voges.
The Australian survived another chance to Collingwood off Onions on 5 and went on to make 80, one more than his previous best of the season. Ian Blackwell bowled poorly in his first spell, with Read cutting him for three fours in his first over to race past 50 off 69 balls.
After 47 overs without a wicket, Thorp made the breakthrough when Voges shaped to turn the ball in front of square and lobbed a catch to Dale Benkenstein at straight midwicket. Thorp also troubled Read after tea, but when he dropped short the visiting captain punched his 15th four through the covers to reach his second century of the season off 158 balls.
Blackwell improved and was handed a wicket when he bowled Paul Franks through a reckless slog. Onions swiftly cleaned up the tail, although the first victim, Graeme White, indicated that he had hit the ball when given out lbw.
Andre Adams sliced a steepler to deep backward point after completing his own five-wicket haul in the morning, also reaching 50 championship wickets for the season.
Earlier, Durham resumed this morning on 272 for 7 and Mustard and Thorp scored 30 off the first four overs, mainly off Mullaney, before Adams bowled Thorp. Mustard was left stranded on 88 when Durham were all out for 351, but would have been happy with four bonus points after going in at 197 for 6.
