It’s time for Matt Hasselbeck to be benched or traded?

San Francisco’s Dashon Goldson picked off Matt Hasselbeck’s first pass of the second half and returned it 40 yards for a touchdown as the 49ers took a stunning 37-7 lead over the Seattle Seahawks today in San Francisco.

It was the third interception thrown in the game by Hasselbeck, who also lost a fumble.

The 49ers capitalized on three Seahawks second-quarter turnovers and turned a 7-7 tie into a 30-7 lead by halftime.

Jeff Reed’s 22-yard field goal as time expired left in the first half came three plays after San Francisco’s Reggie Smith intercepted a Matt Hasselbeck pass and returned it 20 yards to the Seattle 11-yard line.

Before that, quarterback Alex Smith and running back Bryan Westbrook hooked up on a 62-yard pass-and-run play for a touchdown to stretch the 49ers’ lead to 27-7. The 49ers had taken over on downs when the Seahawks, on fourth and four from the 49ers’ 32, passed up a field-goal try and Hasselbeck’s pass downfield intended for Ruvell Martin was incomplete.

The first two Seahawks turnovers earlier in the second quarter helped San Francisco take a 20-7 lead. Smith found receiver Josh Morgan for a 15-yard touchdown pass three plays after Hasselbeck fumbled while being sacked by Travis LaBoy, who also recovered the ball at the Seattle 17.

The Seahawks earlier tied the score 7-7 when Hasselbeck hit Ruvell Martin with an 11-yard touchdown pass. The Seahawks drove 52 yards in seven plays following a 49ers punt. Hasselbeck passes to Chris Baker for 15 yards and Brandon Stokley for 16 yards were key plays.

The 49ers came back with a pair of Jeff Reed field goals to take a 13-7 lead. The first was a 33-yarder that was partially blocked by the Seahawks’ Aaron Curry. The Niners had driven from their own 30 to the Seattle 12, but the drive stalled after a holding penalty.

Reed then kicked a 44-yarder after the 49ers regained possession via an interception by Takeo Spikes of a Hasselbeck pass that slipped through the fingers of intended receiver Michael Robinson.

Earlier, quarterback Smith and receiver Vernon Davis hooked up on a 42-yard touchdown pass to give the 49ers an early 7-0 lead. The touchdown capped a 74-yard, six-play drive after the 49ers received the opening kickoff.
