Scott takes four-shot lead in Scottish PGA

Adam Scott justified his position as pre-tournament favourite at Gleneagles, with a brilliant display in the second round of the Scottish PGA Championship.

Heavy rain meant water was gathering on the greens by 9am and the greenkeepers had to clear the putting surface to allow play to continue.

It did not seem to do Scott any harm - he compiled a flawless 65 for a 12 under par halfway total of 132 and a four shot lead over Richard Green.

Green held the overnight lead after his 65, two shots ahead of Scott.

But while Green got off to a shaky start with two bogeys in his first three holes, Scott opened with two pars before a birdie on the par five 12th took him to six under.

Further birdies at the 16th and 18th then took Scott out in 33 and to eight under par, and that was good enough for a two shot lead.

A superb approach to three feet on the second set up a simple birdie, and when another followed from close range at the next, Scott was 10 under and four shots clear of the field.

Spain's Ignacio Garrido had briefly closed the gap to one shot before running up a triple bogey seven on the first, Green picking up shots at the 12th and 14th to remain Scott's closest challenger.

Scott missed the green by 10 yards on the par three sixth and left his attempted recovery 20 feet short. But the par putt unerringly found the centre of the cup and normal service was swiftly resumed with another birdie on the next.

Two massive blows took Scott to within 20 yards of the green on the 564-yard ninth, and a pitch to four feet brought his seventh birdie of the day and meant he had birdied all five of the par fives.

Green was eight under with two holes to play with Swede Fredrik Andersson two shots further back in third.
