An aggressive bowling display put league leaders Sussex in control of their LV= County Championship match against Lancashire as the visitors finished the second day with a strong lead of 141.

Tim Ambrose smashed an explosive 167 to fire Warwickshire into a commanding 295-run lead over Middlesex on day two at Edgbaston.
Warwickshire were bowled out for 462 but not before Ambrose had put his team firmly in the driving seat with a confident innings that included 20 fours.

Andrew Gale announced his return to the Yorkshire line-up with a century as the Tykes established a daunting 527-run lead over Durham.
Gale, who had dropped himself to make way for Joe Root last week against Middlesex, was back in the side and back in form as he made 124 before declaring on 589 for eight.
