It was over when ...
Defensive end Travis LaBoy sacked J.T. O'Sullivan, forced him to fumble and then made the recovery to seal the Cardinals' win with just under two minutes remaining. Arizona outscored the 49ers, 13-3, in the second half.

Game ball
Edgerrin James didn't do anything flashy. In fact, he didn't have a run longer than 10 yards. But he did rush 26 times for 100 yards, helping to keep the ball away from the 49ers in a decisive second half. The Cardinals, who lost two close games to the 49ers in 2007, had 12 first downs and held the ball for nearly 23 minutes in the second half.

Key stat
The 49ers turned the ball over six times. The Cardinals had no turnovers.
