Sam Hain passed fifty for the third time in five innings this season as Warwickshire continued to dominate Hampshire in the LV= Insurance County Championship.
Hain began the season with centuries against Kent and Somerset and returned to form after a quiet match against Surrey with a faultless 85.
Hampshire had found hope with three wickets in a truncated morning session to fashion a collapse from 83 without loss to 95 for three but half-centuries for Alex Davies, Ed Barnard, and Michael Burgess accompanied Hain.
Barnard, in particular, ground the hosts down to end the day on a stylish unbeaten 91, Burgess partnered him on 60 and Warwickshire on 364 for five, a lead of 135 – although forecast rain on Saturday may thwart their chances of victory.
