CLEVELAND, NOV. 25 -- Miami's Dan Marino hasn't had the big numbers this year that he has put up in past seasons. No 300-yard games. No games with three, four or five touchdown passes.

Another difference this season is that the Dolphins are winning, as they did today in improving to 9-2 with a 30-13 victory over the Browns.

Miami clinched its first winning record since 1987 and moved within a half-game of Buffalo (9-1) in the AFC East. The Bills play at Houston on Monday night.

Cleveland (2-9) has lost six in a row, its longest skid since 1975, and set a team record with its fifth consecutive home loss. The Browns are 0-2 since Jim Shofner replaced Bud Carson as coach, and after the game, quarterback Bernie Kosar sharply criticized the team's work ethic and dedication.

Marino threw for 245 yards and two first-quarter touchdowns today. The performance put him over the 30,000-yard career passing mark. He reached that level in fewer games than anyone in NFL history.

"I have fun all the time when we win," said Marino. "Sure, everybody misses throwing for 300, 400 yards and a lot of touchdowns. But today was an example. We got ahead and we didn't have to throw. You just try to control the ball and keep the clock moving."

Sammie Smith rushed for 96 yards on 24 carries, including a career-best 33-yard run late in the game and a four-yard second-quarter touchdown.

Miami's more conservative offensive approach is possible now that the Dolphins have the No. 1-ranked defense in the NFL. Kerry Glenn scored today on a 31-yard interception return in the second-quarter.

Kosar, who turned 27 today, was 17 for 37 for 191 yards with two interceptions. He declined to take questions afterward, instead choosing to make a statement.

"I really question what type of work ethic and dedication that we have to this organization and for the pride that we should have playing for the Cleveland Browns and playing professional football," Kosar said.
