Somerset 215 (Wagner 72, Davey 46, Rushworth 5-47) and 90 for 2 (Dickson 36*, Umeed 20*, Barnard 2-27) lead Warwickshire 273 (Barnard 73, Davies 44, Rhodes 42) by 32 runs

Rain and bad light have chopped 125 overs from days one to three but, with better weather forecast for the fourth, a decisive result remains possible. Quick wickets could herald a Warwickshire victory bid, or the captains could simply agree a target overnight.

After Warwickshire resumed the third morning on 112 for 3, Davey struck with the fourth ball which Dan Mousley edged low to Andy Umeed at second slip. Alex Davies fell lbw to Jack Brooks and when Michael Burgess edged Wagner behind, the home side was 147 for 6, still 68 behind. Somerset sensed a lead.

Barnard had set down roots, though, and received obdurate support from the in-form Danny Briggs. Confident after his 99 at Lord's last week, the former Hampshire and Sussex player contributed 38 off 68 balls to a stand of 93 in 25 overs which moved Warwickshire in front.

Briggs scooped Wagner to long leg and Craig Miles gloved the New Zealand international behind before Barnard's excellent innings was terminated by a skied attempt to hoist Davey straight.

The Worcestershire product had ensured Warwickshire a handy first-innings lead, though, and Somerset faced an awkward 15 overs batting before tea. Openers Tom Lammonby and Sean Dickson made 39 from the first 14 before the former clipped Barnard to short mid-wicket in the final over of the session.

Barnard's happy day continued when Lewis Goldsworthy feathered a pull to wicketkeeper Burgess. Still eight runs behind with two wickets down, Somerset needed ballast and Sean Dickson (36 not out) and Umeed (20 not out) supplied it with an important unbroken stand of 40 in 12 overs. Dickson's two hours of resistance, in which he struck just three of 84 balls faced to the boundary, was exactly what his team needed in the circumstances.
