Greig Hutcheon, the reigning champion and the dominant force on the Tartan Tour in recent seasons, will be attempting to achieve a rare feat by claiming back-to-back titles.
Not since Ross Drummond produced a double whammy in 1989 and 1990 - he also won successive crowns in 1986 and 1987 - has a player successfully defended the domestic circuit's most cherished prize and Hutcheon will tee-up in purposeful mood after sharing fifth in last week's P&H Championship.
Robert Arnott, the Bishopbriggs veteran who won that P&H title at Dundonald, will be expected to be at the sharp end of affairs again while four-time champion Drummond and the 2001 PGA champion Andrew Oldcorn bolster the over-50s brigade. Chris Kelly, the 2003 Scottish PGA champion, warmed up for his assault on the £50,000 championship by blasting a seven-under 63 en route to victory in the Portpatrick Pro-Am at the weekend. David Orr and Graham Fox are also among the former national champions in action over the next three days.
n Blairgowrie's Scottish Boys' champion Bradley Neil put on his Sunday best form to finished third in the prestigious Lytham Trophy at Royal Lytham and St Annes, writes Colin Farquharson.
After opening rounds of 75 and 71, Neil stepped up a gear with the best two-round aggregate by anyone in the field yesterday, bettering the South African winner Thriston Lawrence and the Dutch runner-up Darius Van Driel.
Neil shot rounds of 68 and 69 over the testing par-70 lay-out for a final total of three-over-par 283.
Lawrence won by a single shot from Van Driel with a one-over 281.
n Felipe Aguilar produced a breathtaking back nine to storm to The Championship at Laguna National title in Singapore. Aguilar began the day four shots off the pace and made two birdies in his opening nine holes before his round came to life after the turn.
The Chilean recorded a further six birdies, but it was his eagle on the last that took him to 22 under par overall and a one-shot victory over American David Lipsky and Anders Hansen of Denmark.
Aguilar came home in 28 to record a 10-under-par final round and seal his second victory on the European Tour, with his other success coming in the Enjoy Jakarta Astro Indonesia Open in February 2008.
"It's been a bit of a drought for six years," he said. "I've lost a couple of times in play-offs and had a couple of top threes and top fives, but never was able to get the round going on the last day, so it is nice to finally do it."
Lipsky can feel aggrieved to finish runner-up after carding a bogey-free 65, while Hansen, who was joint overnight leader, recorded a five-under-par round for the third time this week.
Rahil Gangjee of India finished fourth on 19 under par overall, while England's Chris Wood was a further shot back after a round of 67, with compatriot Tommy Fleetwood finishing in a tie for eighth.
