Jack Leaning and Grant Stewart scored contrasting half-centuries as Kent piled on the runs on a rain-affected day two of their LV= Insurance County Championship clash with Northamptonshire. Captain Leaning ground his way to a 120-ball fifty to build on the work of Ben Compton, who ended with 140, and Zak Crawley and Daniel Bell-Drummond’s half-centuries. On the other hand, Stewart was given a licence and used it to bash five sixes in 34 deliveries on his route to the milestone – before he ended up on 61 – as Kent declared on 519 for nine. All-rounder Stewart and Darren Stevens then made early in-roads by displacing Ben Curran and Emilio Gay as Northamptonshire ended the day on 21 for two – 498 runs behind.
