The Giants' Michael Strahan (92) and Sam Madison had reason to smile on Sunday.

It was over when ...
Giants defensive end Osi Umenyiora sacked Trent Dilfer, stripped him of the ball, scooped up the fumble and raced 75 yards for a touchdown (third longest in Giants history). The score gave the Giants a 26-7 lead with just under 13 minutes left in the third quarter, and the way their defense was playing, the game was all but over.

Game balls
The sack gave Umenyiora his NFL-leading eighth of the season. Defensive ends Michael Strahan and Justin Tuck posted 2½ and 1½ sacks, respectively, to lead New York's defense. Giants running back Brandon Jacobs rushed for 107 yards and a touchdown.

Key stat
The 49ers had 13 penalties for 82 yards, which often nullified positive gains.

Noteworthy
Amani Toomer's touchdown in the first quarter gave him the franchise record for career with 49 (passes Kyle Rote 48). It also marked the first time the 49ers allowed a touchdown on an opening drive this season. ... The Giants defense has 25 sacks in their last five games. The defense also has allowed 69 points in the last five games, after allowing 80 in their first two games of the season.
