Warwickshire v Nottinghamshire: Ambrose ton damages Notts

Tim Ambrose scored an unbeaten century for Warwickshire to further dent Nottinghamshire's hopes of winning the County Championship title.

Ambrose's 151 not out, his first ton of the season, was backed up by Ian Blackwell (69 not out) and Chris Wright (53) as the leaders declared on 504-6.

Third-placed Notts, who trailed the hosts by 27 points going into the game, closed 316 runs behind on 188-4.

Alex Hales (80no) passed 3,000 first-class runs, Chris Read unbeaten on 54.

The pair have so far put on an unbroken 119 for the fifth wicket after Notts had slipped to 69-4.

Wright took 2-67, including the wicket of James Taylor who made only one before treading on his stumps, as Warwickshire moved a step closer to the Championship title.
