|Durham 10pts, Notts 8pts|
Adam Voges hit an unbeaten 68 as County Championship leaders Durham were forced to settle for a draw with champions Nottinghamshire at Chester-le-Street.
Notts were set 272 in 58 overs to win after Paul Collingwood and Dale Benkenstein both hit half-centuries to enable Durham to declare on 181-3.
Despite 40 from Karl Turner, Notts slipped to 141-5 before Voges and Paul Franks saw them to the close on 172-5.
The draw means Durham are six points clear of second-placed Lancashire.
Somerset, in third, are six points further adrift, and fourth-placed Warwickshire another three, albeit with a game in hand on their rivals.
After rain washed out most of Thursday's play, Durham were always in a race against time to set Notts a target they might choose to chase.
After Ben Stokes fell early on, Collingwood and Benkenstein put on 92 for the fourth wicket before the former England batsman suffered a back spasm and retired hurt for 53.
Ian Blackwell replaced him and hit three sixes off Graeme White in making 29 not out off 11 balls to set up the declaration, with Benkenstein unbeaten on 61.
Notts soon lost debutant Sam Kelsall and Riki Wessels, but Turner looked comfortable until he was trapped lbw by Blackwell.
Voges and Steven Mullaney put on 69 for the fourth wicket before Phil Mustard took a brilliant one-handed catch to remove Mullaney and give Graham Onions his eighth wicket of the match.
First innings centurion Chris Read was bowled by Blackwell for a duck to give Durham a glimmer of hope but Voges and Franks played out the remaining overs.
CLOSE OF PLAY SUMMARY
BBC Newcastle's Martin Emmerson:
"Sadly the rain robbed us of a result here for the second time in two home games in the Championship.
"If any positives come from the match it's the fact Lancashire didn't win either and Durham's slender lead has stretched to six points over them.
"More importantly they still have three competitions to play for in August and I can't remember that being the case before."
