Matches were postponed yesterday because of rain but officials are determined to fit a full day of bowls in today.

Slow greens mean tighter matches and more chance of underdogs causing unexpected results.

Four-time player of the tournament and three-time singles champion Shane Garvey says the big guns will have to be on guard in the tricky conditions.

"Wet greens are a real leveller," he said.

In the fours on Sunday, Garvey's star-studded Engadine side nearly came unstuck in sectional play, losing to an unheralded Dapto Citizens side.

Engadine eventually progressed, but it was a reminder for Garvey that he will need to be on his game today.

"I'm in a section where, if I play well, I should go through. But if some of the guys I'm playing have a great day and I'm a little bit off, you never know," Garvey said.

"You sort of walk around with a target on your back because everyone is out to get you, so players lift when they play you."

Garvey's toughest match in sectional play will be against Bulli's Paul Hancock.

Other contenders in the singles will be Matt Sargeant, John Green and Geoff McGillivray. The draw seems wide open and an up-and-comer could steal the limelight.

Oak Flats' Luke Cocksedge is one player Garvey says has a promising future.

"I coached him at Oak Flats - he just won the singles there. He's someone who could shine. He's been playing good bowls. He might cause a bit of grief - he's a real dark horse," said Garvey.

Maltese international Shaun Parnis (Dapto Citizens) is another contender.
