Mike Rae threw to Kris Haines for a six-yard touchdown with 18 seconds left to give the Express a 23-20 U.S. Football League victory over the Boston Breakers in Los Angeles last night.

The touchdown ended a six-play, 80-yard drive for Haines' second touchdown of the game.

Rae, relieving an injured Tom Ramsey, completed nine of 12 passes for 104 yards, including the winning touchdown. Haines caught six passes for 86 yards.

"If we could have caught every ball we had a chance to catch, this could have been a much easier win for us," said Express Coach Hugh Campbell, whose receivers fumbled away three catches. "But we hung in there, and thought good thoughts.

"A lot of teams that dropped three passes would sink. But this team didn't wilt, or get down over missed opportunities."

The Breakers' Tim Mazzetti had kicked two Boston field goals for a 20-16 lead over Los Angeles at 7:54 of the fourth quarter, a lead that held until Los Angeles' final-seconds touchdown.

Tony Davis and Richard Crump each had scoring runs for Boston.

Ramsey injured his Achilles' tendon after completing 10 of 18 attempts for 117 yards and a touchdown.
