Adil Rashid and Steve Patterson impress to lift Yorkshire to a challenging score

Yorkshire showed the resilience of champions to thwart Warwickshire's advance on a weather-affected second day of their Specsavers County Championship tussle at Edgbaston.

At 85 for four and 209 for six, Yorkshire were in jeopardy of coming in far below the total they had in mind when they won the toss and batted.

But they recovered to 368 for nine by the close, thanks heavily to Adil Rashid's 33rd first-class half-century (63) and Steve Patterson's second (62 not out from 74 balls, including 11 fours).

That is a position from which Yorkshire will seek to apply pressure to a Bears batting unit to which they have caused much trouble in recent years, not least at Edgbaston where they have won emphatically on their last three championship visits.

After bad weather prevented play until 1.30pm, Warwickshire quickly struck two big blows by removing the overnight half-centurions.

Jack Leaning edged Chris Woakes to wicketkeeper Tim Ambrose to depart for 51, before Gary Ballance, whose 68 contained 10 fours) nicked Keith Barker behind.

At 209 for six, the door was ajar for the home side but Liam Plunkett counter-attacked vividly, striking Barker for three successive fours in a 30-ball 26. That cameo, in a stand of 43 in 57 balls with Rashid, signalled a swing in momentum.

After Plunkett edged a Rikki Clarke outswinger, Rashid found another punchy partner in Patterson. The pair added 91 in 20 overs before was Rashid was castled by the persevering Woakes and departed after a 104-ball innings containing nine fours.

Barker induced an edge behind from Jack Brooks but Ryan Sidebottom accompanied him through to the close.

The pitch looks good for batting - as good as Yorkshire evidently thought it was when they elected to bat on it - but the visitors will enjoy the prospect of putting some pressure on opponents they have twice dismissed for less than 100 in the last two seasons.

However with Ian Bell and Jonathan Trott having already shown their class in the championship this season, with scores of 174 and 219 not out respectively, and further time likely to be lost to the weather, these sides could still be seeking a first win of 2016 after this Division One match.
