Resurgent Warwickshire stormed back into contention to retain the Division One title in the LV= County Championship when beating Nottinghamshire by 216 runs at Edgbaston.
Off spinner Jeetan Patel led an outstanding bowling performance on a slow pitch, taking 8-128 in the match as the visitors were rolled over for scores of 217 and 210.
A back-to-form Alex Hales, making 58 from 182 balls, his first half-century since April, threatened to hold off Warwickshire before the last six wickets went down for 56.
Last year Patel took 51 wickets in helping to win the championship and now his 15 in successive victories over Middlesex and Notts have put the champions within range of current leaders Sussex.
Although Hales should take confidence from breaking free after a run of eight single-figure scores in 10 championship innings, Notts ultimately fell some way short.
From the first hour - when they added a mere 10 runs from 15 overs - it was clear they believed a target of 427 would be some way out of reach unless they batted exceptionally well.
The departure of Steven Mullaney, whose off stump sent spinning when a ball from Chris Woakes skidded through, would not have increased their trust in a dry fourth-day pitch but in reality it was not offering a great deal of help to the bowlers.
There was some slow turn for Patel and in the main Warwickshire's strategy was to rotate the four seamers in support of the New Zealand off-spinner.
For a long time it was a hard slog, broken up only when Michael Lumb edged a catch behind off Keith Barker and again when James Taylor fell leg-before in a short, sharp spell by Boyd Rankin.
The door opened when Hales, having batted so diligently for three-and-a-half hours, went down the pitch to Patel but succeeded only in pushing a catch to the alert Porterfield at short mid-on.
Nottinghamshire's subsequent slide, which started with Samit Patel falling to a catch at square-leg that the batsman appeared unhappy with, would have been a major disappointment. Only David Hussey stayed for any length of time and the match was quickly over when he edged Woakes, with the new ball, to first slip.
