Olly Hannon-Dalby celebrated 250 career first-class wickets as he ran through Northamptonshire’s lower order on day two of this LV= Insurance County Championship game at Northampton.In a miserly four-over spell, Hannon-Dalby claimed four victims for just five runs as Northamptonshire added 31 runs to their overnight total to close on 451 all out. The 33-year-old-seamer is now the second leading wicket-taker in Division One with 29 scalps, just behind Keith Barker’s 32.But despite his efforts Warwickshire still face a tough task in this game after some highly disciplined Northamptonshire bowling performance restricted scoring to just 1.8 an over with only two boundaries coming in the first 25 overs of the visitors’ reply.
