SEATTLE, OCT. 1 -- Derrick Fenner scored three touchdowns, Dave Krieg passed for two and Rufus Porter inspired the defense as Seattle became the last NFL team to win a game, beating previously unbeaten Cincinnati, 31-16, tonight.

Porter had two of three sacks by the Seahawks, next-to-last in the NFL in defense entering the game, and thwarted Boomer Esiason and his offense. The Bengals (3-1) were limited to three Jim Breech field goals until Mitchell Price returned a punt 66 yards for a fourth-quarter touchdown. "They just shut us down," said Esiason.

Krieg dinked and dunked the Seahawks (1-3) to a 17-9 lead after three quarters as Fenner, from Oxon Hill High, scored on runs of three and four yards.

Then, on the first play of the fourth quarter, he found Tommy Kane deep on the left sideline behind Rickey Dixon and hit him in stride for a clinching 63-yard touchdown. Krieg had only one touchdown pass in his three previous games and his longest completion had been 28 yards.

Later in the quarter, Seattle punter Rick Donnelly managed to retrieve a bad snap and kick a line drive deep downfield, but returner Price broke three tackles, then twisted and turned for his score.

Krieg (17 of 24 for 217 yards) marched the Seahawks 80 yards for the last score, a two-yard pass to Fenner, who has six touchdowns in two games. The key play was a 52-yard, third-down pass to Jeff Chadwick.

In a pivotal series with Seattle leading, 10-6, in the third quarter, Porter deflected two passes and sacked Esiason (10 of 23, 128 yards, three fumbled snaps), drawing a personal foul penalty for throwing the quarterback to the ground. But that fired up the crowd of 60,135 to such a level that Cincinnati took a delay-of-game penalty because it couldn't get off a play. "He had an outstanding game," Esiason said of Porter. "He made some great plays, even if some were questionable."

On the next series, the Seahawks went 56 yards in five plays for Fenner's three-yard touchdown. The drive included John L. Williams's 22-yard run in which he reversed field and got blocks from Krieg, among others, to reach the 16.
