Olly Hannon-Dalby carried Warwickshire’s bowling attack as Northamptonshire gritted their way to 200 for five on a weather-affected opening day of their LV= Insurance County Champions match at Edgbaston.

The visitors, put in, advanced to 171 for two as Emilio Gay (77, 146 balls) and debutant Karun Nair (78, 177) added 147 in 46 overs.

But Hannon-Dalby powered his side back into the game after tea with bowling of sustained accuracy and menace. His 19-7-29-3 was worth many a five-for harvested in more helpful conditions.
