Bowlers put Yorks in control
Yorkshire's bowlers underpinned their team's position at the top of Division One in the LV= County Championship by maintaining a recent stranglehold on Warwickshire in the latest meeting at Edgbaston.
Nine wickets fell to the pace attack and one to 18-year-old spinner Karl Carver as the home side were dismissed for 228, with a solitary half-century for Jeetan Patel from the number nine position.
In the last 13 months Yorkshire have twice chalked up big victories over the midlanders, but it may not be entirely straightforward this time.
In a tricky final session, Alex Lees, unbeaten with 40, and Andrew Gale (31 not out) were fully tested in taking them to 82 for two after a double strike by Chris Woakes in successive overs.
When Warwickshire opted to bat first, the conditions played to Yorkshire's strength in the seam bowling department. There was pace and bounce in the pitch and Richard Pyrah also got the ball to swing in a damaging first spell.
When the 31-year-old all-rounder removed Varun Chopra and Jim Troughton in three balls, he had taken four championship wickets in a week, which equalled his return from nine appearances in the previous two seasons.
With the ball nipping around after lunch, Jack Brooks bagged Sam Hain and Chris Woakes in successive deliveries and Warwickshire were on the rack at 124 for seven when Pyrah benefited from the fifth catch at first slip in the innings.
However, Yorkshire were held up, first by Keith Barker with 36 and then the ever-dangerous Patel, who clattered three sixes - two off newcomer Carver - in an unbeaten 63 from 67 balls.
It was the New Zealander's third championship score of more than 50 at Edgbaston this summer. Previously he made 74 against Sussex and 105 against Middlesex.
Yorkshire's position as serious title contenders is likely to be sustained by the continued of rotation of their seam attack. Brooks is the one ever-present member, having 40 championship wickets so far.
Pyrah is playing his third game following Liam Plunkett's return to the Test arena, and for this match one international bowler replaced another. Ryan Sidebottom returned after a hamstring injury, while Tim Bresnan was rested because of an elbow injury.
Similarly they have been able to pursue alternatives in the spin department, with Adil Rashid away on paternity leave.
Azeem Rafiq deputised against Sussex and Northallerton-born Carver got his chance here, a week after his season's best return of five for 37 for the academy in a league fixture against Scarborough.
A left-arm spinner in the England Under-19 squad last year, he took his first wicket when Barker went down the pitch and gave Aaron Finch his fourth slip catch on the day.
When Finch was off the field in the afternoon, Lees went into first slip to pouch chances from Tim Ambrose - giving Pyrah three for 37 - and then from Rikki Clarke off a lifting delivery from Steven Patterson.
