Neil Lomax scored on a 22-yard scramble and set up two other scores during a string of 10 straight pass completions today as the St. Louis Cardinals downed the New Orleans Saints, 30-3, for their fourth victory in four games since installing the rookie as regular quarterback.

Jack-of-all-trades Roy Green scored the final St. Louis touchdown on a 44-yard run off a direct snap while lined up ahead of the punter in punt formation. That provided a 24-3 lead early in the fourth quarter and assured the Cardinals their longest success streak since 1978, their first seven-victory year since 1977, a 7-7 record and an outside chance at a wild-card playoff spot.

Lomax completed three of three passes for 30 yards en route to his touchdown run for a 7-3 lead with 13 seconds left in the first period. He duplicated his three-for-three accuracy, for 48 yards, to set up Wayne Morris' one-yard touchdown dive at 4:07 of the second period. He made three more without a miss for 47 yards before Neil O'Donoghue's first of three field goals, from 41 yards with 29 seconds left in the half made it 17-3.
