CINCINNATI (AP) - Mark Clayton put a little sizzle into Baltimore's steadily evolving offense.

The fourth-year receiver threw a touchdown pass on a reverse, then made a spectacular one-handed catch for a 70-yard score on Sunday, helping the Ravens keep pace in the AFC North with a 34-3 victory over the Cincinnati Bengals.

The Ravens (8-4) have won six of their past seven games with a renowned defense and an offense coming into its own behind rookie quarterback Joe Flacco. Each week, the Ravens give him a little more freedom and a little more of the playbook.

Against the Bengals (1-10-1), they added a page for Clayton, a first-round draft pick who emerged as a dual scoring threat on a cold, rainy afternoon.
