Sam Hain’s high-class century kept Warwickshire afloat as Lancashire’s bowlers impressed on the opening day of their LV= Insurance County Championship tussle at Edgbaston. The home side was all out for 292 just before the close with Hain the last to fall for 130 (228 balls, 17 fours). The accomplished knock continued the 26-year-old’s excellent red ball form, his last four championship innings having brought 449 runs for twice out.
