Hamilton wrecked the home side's top order with four wickets in 21 balls. Leicestershire eventually collapsed to 131 all out as Yorkshire won by 100 runs with nearly 12 overs to spare.
The visitors won the toss and reached 231 for 6, with Craig White top- scoring on 48. At 101 for 1 after 21 overs Yorkshire looked set for a big total. But Matthew Brimson bowled White and Leicestershire pegged Yorkshire back in the remaining overs, as they set what looked a modest target.
However, Hamilton's burst put paid to Leicestershire. Only Jon Dakin offered much resistance, top-scoring with 41.
Hamilton finished with 4 for 33 and White 2 for 21. The one consolation for Leicestershire was that their first-ever floodlit game at Grace Road produced one of their biggest crowds for years.
The Essex off-spinner Peter Such halted a Lancashire batting resurgence with a six-wicket haul in the County Championship match at Old Trafford yesterday. It was the first time the 35-year-old Such had claimed five or more wickets since his success for England in the last Ashes Test at Sydney.
Lancashire, however, could feel pleased enough about their 298 for 8 off 104 overs on a pitch helpful to bowlers. The Lancashire captain, John Crawley, set the right example, putting on 117 with Mark Chilton before Such dismissed Chilton for 71 and Crawley for 51.
Such then suffered some punishment from Andrew Flintoff, who hit four sixes in a 43-ball half-century. But he hit back with four more victims, including Warren Hegg just before the close, to end with 6 for 136.Reuse content
