Quick Take: Flacco, Harbaugh win debuts

It was over when ...
Ravens fullback Le'Ron McClain ran for 4 yards on third-and-short with two minutes remaining, allowing the Ravens to keep possesion and run out the clock.

Game balls
Rookie QB Joe Flacco didn't have spectacular statistics (15-of-29, 129 yards) but he showed poise in the pocket and managed the game in the second half like a veteran. The 6-foot-6, 230-pounder even scampered 38 yards down the sideline for a touchdown. He also didn't have a turnover.

Key stat
The Ravens had the ball nearly 13 minutes longer than the Bengals, but Cincinnati squandered its chances. The Bengals converted just 2 of 13 third-down tries and failed on both of their fourth-down attempts.

Noteworthy
Carson Palmer's 35.2 rating was the lowest of his career. ... Flacco's TD run was the longest by a Ravens QB in team history. ... The Bengals have lost nine of their last 11 games on the road. ... Ravens CB Corey Ivy left the game late in the fourth quarter with an injured leg. ... The former Chad Johnson was held to one reception; it was only the eighth time in the Bengals receiver's career he was limited to one catch or fewer.
