No leftie limit for World Cup: Starc

Mitchell Starc insists there's room for three left-arm quicks in Australia's World Cup squad and says aggression and wicket-taking are the big assets he brings to the table.

Starc, Mitchell Johnson and James Faulkner are all vying for spots in the World Cup in Australia and New Zealand starting in three months.

Johnson was the only one of the trio selected for the first two of five one-day internationals against South Africa, though the other two are tipped to get a run in the later games.

Asked if there was room for all three in the World Cup squad, Starc said "I don't see why not.

"You pick three right-armers all the time. Why not left-armers? It's something different.

"It's about picking the guys that are right for that team at any given time and making sure that the guys that are on the fringe, or not there, are performing and keeping fit and making sure they are ready to go if called upon."

Starc, who picked up seven wickets in a Sheffield Shield game in Adelaide earlier this week, noted all the bowlers had different attributes.

"I like to think I'm a wicket-taker and a pretty aggressive bowler," Starc said.
