In Chicago, John Roveto's second field goal of the game, a 24-yard chip shot with 2:07 left, clinched the victory over Los Angeles.
The triumph broke a two-game Chicago losing streak and left both teams with 2-2 records. A crowd of 10,936 attended in rainy weather, compared to 21,949 at last week's snowy home opener. This time there were 7,377 no-shows.
"We finally won one in Chicago," said Blitz Coach George Allen. "I don't know if our budget can stand it but we gave all 40 guys a game ball. The defense sucked it up at the end. We took the ball away three times. That's the way it has to be."
The Blitz took a 10-0 halftime lead and did not allow the Express to cross midfield in the first half.
Roveto put Chicago ahead with a 38-yard field goal with 5:43 left in the first quarter and Kevin Long punched across from the one with 25 seconds left after a 64-yard drive.
Los Angeles struck shortly after taking the second-half kickoff, when Tom Ramsey threw a 40-yard touchdown pass to Tony Boddie. A poor punt by Chicago's Frank Garcia gave the Express the ball at the Blitz 31, but a 45-yard field goal attempt by Vince Abbott was wide.
Chicago came back with a 73-yard drive ended by Greg Landry's five-yard scoring pass to Doug Cozen for a 17-7 lead.
"Chicago has the best personnel of all the teams we've played so far, no question about it," said L.A. Coach Hugh Campbell. "They present you with a lot of problems, especially their defense.
