David, as slight as he is short, walks back to his mark swinging his skinny arms as hard as he dares to take his attention off the terrifying thump of his heart. Can it really be that loud?Many metres away, to the right of the crease, towering above pads almost tall as David and hunched over a bat hewn from most of a decent-sized willow tree, is Goliath.David turns. Stands. Waits. Trembles.Goliath grunts."Holy Moses," David thinks as he fidgets aimlessly with his field, "what the hell did I have to go and get that Philistine's opener out for?"The Israelites' captain gets tetchy and trots over from extra cover. "Listen, fella," he snaps at David, "if you stand still for much longer people are going to think you're a bloody statue."David knows the game is up, that he doesn't have 40 years to spend in this wilderness, T20 cricket doesn't work like that, and he's going to have to bowl to the monster sooner rather than later."Oh well, here goes nothing. What's my psalm again? Oh yeah . The lord is my shepherd; I shall not want ."David works through his mantra as he runs, and when his left foot hits the ground to take the pace before his delivery stride, he ends with . "and I will dwell in the house of the Lord forever."His right foot hits the crease and his ice-cream stick of a left arm cuts a crescent through the air above his head.Goliath has cocked his terrible eye and his bat, issued his last grunt and forgotten to breathe.And he waits ...... Too long! Yorked!As David got to, "Yea, though I walk through the valley of the shadow of death, I will fear no evil", he saw the daylight between Goliath's massive feet and his bat.It looked as big as a parking space. More than enough, then, to smuggle a cricket ball through and onto stumps that didn't quite reach up to Goliath's knees.An awful roar issues from the giant's throat as he throws back his massive head in anger and frustration.David can smell his sulphuric breath as he sprints past him in giddy triumph, teammates in tow. He'll be up for a few tunes on his lyre in the pub tonight, china.David slaying Goliath is among sports' most compelling narratives, and it's part of what's making the franchise T20 competition a drawcard.Aubrey Swanepoel, for instance, has been bowling offspin for Griquas, Northern Cape and the Knights for more than 10 years. During that time he has claimed the wickets of Ashwell Prince, David Miller, Colin Ingram, Temba Bavuma and Stiaan van Zyl - facts that are likely to be known only to those who are part of the subculture that domestic cricket has been relegated to in its continuing separation from the international game.When the short, slight Swanepoel shambles in to the crease and lets fly with a slinging right arm, you might not think something special could happen.Aiden Markram probably also didn't think so when Swanepoel bowled the second ball of the 15th over to him in the Knights game against the Titans in Kimberley on Wednesday, especially as he had put away the offie's previous offering for four.But Swanepoel induced a mighty heave from the golden child of South African batting that was caught at deep midwicket - by Swanepoel's brother, Patrick Kruger, nogal.And that with a sizeable crowd at the Diamond Oval and an exponentially bigger audience watching on TV.That many would have been at the ground or tuned in principally to see Dale Steyn's return from a year on the sidelines through injury didn't matter.A layer of Swanepoel's relative obscurity would have been peeled away. More people knew his name; maybe even his nickname: "Appel". Except on Wednesday, when it was David...
