Left cornerback Elvis Patterson provided most of the New York Giants' offense today by setting up two touchdowns in a 21-13 NFL victory over the New Orleans Saints.

He intercepted a pass in the second quarter and recovered a fumble in the fourth. He has started all season because the team's three-time Pro Bowl cornerback, Mark Haynes, didn't sign a contract until two weeks ago. Haynes must be activated by next week.

The interception enabled Phil Simms to pass to Bob Johnson for a six-yard touchdown midway through the second quarter.

Then, after Patterson recovered a bobbled punt at New Orleans' 12, teammate Joe Morris scored the first of two touchdowns in the fourth period. Morris carried three straight times on the series, finished with a five-yard plunge to give the Giants a 14-6 lead.

Two minutes later, defensive end Leonard Marshall batted a pass high into the air and intercepted it at the Saints' 22. Seven plays later, Morris scored from the one.

New Orleans scored on Morten Andersen's 33-yard field goal in the first quarter and a 43-yarder in the fourth.

The Saints also scored in the final minute on a 17-yard pass from Dave Wilson to Eric Martin.

Morris finished the game with 104 yards rushing, a single-game performance he bettered only once with a 107-yard game against St. Louis last year.

Simms completed 18 of 27 passes for 159 yards.
