Warwickshire took three wickets late in the day to gain the upper hand in their crucial LV= Insurance County Championship Division One clash against fellow title chasers Yorkshire.
With a lead of 224, Warwickshire reduced Yorkshire to 50 for three before the close of day two at Emerald Headingley as Tim Bresnan returned to haunt the county with which he won two Championship titles in 2014 and 2015.
The veteran all-rounder contributed a valuable 36 in Warwickshire's second-innings 176, then took three catches in the slips as Yorkshire lost Adam Lyth, George Hill and Dawid Malan before stumps – the latter off the last ball of the day.
It leaves Yorkshire needing to score 174 with seven wickets in hand, knowing that the loser of this match is almost certainly out of the title running.
