County Championship D1, The Brit Oval, day three (close): Surrey 427-9d & 295d v Lancashire 234 & 27-0
Lancashire must chase down 462 runs on the final day to win the Championship after prolific Mark Ramprakash helped Surrey set a 489 target.
Surrey - with a 193-run first innings lead - started on 21-0 and declared on 295-5 as Ramprakash struck 130 not out.
In the process, the ex-England batsman passed 2,000 runs for the season.
Lancashire reached 27-0 at close and need a win to secure the title after Durham won to go top and Sussex look set to beat Worcestershire.
Ramprakash has proved to be Lancashire's nemesis in the match with centuries in both innings for Surrey and he has now scored 10 tons this season.
All we can do is go out and play tomorrow just like we have all season and maybe we might surprise a few
Lancashire bowler Glen Chapple
His 97th career century also helped him notch 2026 runs for the season with an average of 101.30 to become the first batsman ever to achieve feat in combination.
It was the second year in a row that he has achieved an average of over 100 and the sixth time in his long career that he has scored hundreds in both innings of a match.
Lancashire have a daunting task ahead to win the match but bowler Glen Chapple insists the Old Trafford side have not given up.
"We all believe that it is still possible to win this game," he said.
"All we can do is go out and play tomorrow just like we have all season and maybe we might surprise a few. We all have to give serious effort if we are to win.
"It's been a frustrating couple of days as we haven't bowled that badly, especially in the first session of the match.
"We had our chances but just didn't take them on a good surface, although you can't take it away from Ramps who played magnificently. Good players are entitled to get runs on a good wicket."
