The Open 2012: Leader Adam Scott determined to stay calm

Australia's Adam Scott says he will maintain his normal routine as he heads into the final day of the 2012 Open with a four-shot lead.

The 32-year-old, who is chasing his first major title, shot a two-under 68 to build a cushion at 11 under par.

Overnight leader Brandt Snedeker dropped three shots on Saturday to slip back to seven under and is tied in second with Northern Ireland's Graeme McDowell, who carded a 67.
