A day after Michael Diamond's Olympic dreams were revived, another of Australian shooting's 2004 medal hopes Russell Mark failed to qualify for Athens.

Mark held a 17-point lead in the men's double trap event heading into the second and final Olympic shooting trial in Sydney but finished two points behind the second qualifier, Tom Turner.

Shooters are ranked on their cumulative point scores after trials in January and February, with the top two qualifiers securing nominations for the Olympic team.

Head coach Greg Chan said Turner finished first, with Steve Haberman - who was ranked fourth after the first trial, 29 points behind Mark - claiming the second and final spot.

"The bottom line is that Steve Haberman beat Russell into the team by two points," he said.

"Yesterday and today (Mark) didn't shoot well at all."

Mark won gold for Australia in the men's double trap in Atlanta in 1996, silver in Sydney 2000 and came second at last year's world championships.

His failure to qualify increases the pressure on Diamond, who was yesterday given the opportunity to shoot-off for an Olympic berth in the trap after missing the first trials due to a messy court case.

Diamond resumed his training with a bang today, hitting 24 of his first 25 targets in a performance Chan described as extraordinary.

Chan said Mark's failing to qualify was not the scenario he had in mind.
