County Championship D1, Old Trafford, day two (close): Surrey 337 v Lancashire 341
Carl Hooper proved a painful thorn in Surrey's side with a wonderful century at Old Trafford.
Surrey, five points behind leaders Sussex, looked sure to dismantle the hosts when they took four middle-order wickets for just 14 runs.
Removed in that time were Stuart Law (67) and Mark Currie (56) as Lancashire descended to 183-6.
But former West Indies skipper Hooper had other ideas, stroking 114 off 147 balls as wickets fell all around him.
He looked to be running out of partners as Azhar Mahmood (4-76) and Ian Salisbury (3-70) moved in to finished off the tail.
But number 11 Gary Keedy withstood 36 balls for a solitary run as Hooper filled his boots at the other end, finally perishing at day's end to Azhar.
