The last thing rival captains Alistair Campbell of Zimbabwe and Stephen Fleming of New Zealand want is their pre-quarter-final match truncated or decided by the tie-breaker.

Under the rule, being applied for the first time in a major tournament, in the event of 25 overs-a-side not being completed in a match, five bowlers from either side will aim at a set of stumps and the team scoring most hits will be declared the winner.

Echoing the fears of many of his counterparts in the nine-nation tournament, Campbell said ``Basically, it is a knockout tournament. It could be one game, it could be more.''

He, however, felt Zimbabwe had turned the corner after their dramatic one-off Test victory over India earlier this month. ``We won against India, the guys are confident and are playinggood cricket.

``In one-day games, nobody is an underdog. We are taking it very seriously,'' he said.

``It's a 50-50 opportunity,'' said Fleming, who led New Zealand to the Commonwealth Games bronze medal.

The winner of tomorrow's pre-quarter-final match will go on to meet World Cup champions Sri Lanka, seeded directly into the quarter-finals along with Australia, England, India, Pakistan, South Africa and West Indies.
