Seeking to avenge their week 2 loss in Seattle, the 49ers defense held Seahawks quarter back Russell Wilson and running back Marshawn Lynch to 199 passing yards and 72 rushing yards respectively. 4 field goals from kicker Phil Dawson, an 8-yard touchdown pass to tight end Vernon Davis, and a 51-yard rush by running back Frank Gore in the fourth quarter lifted the 49ers to a 19-17 victory and improved their record to 9-4. The win also continued the Seahawks' losing streak at Candlestick Park since 2008. This would not be the last time these two teams would meet as they met again in the 2013 NFC Championship game.
Question: how many points did 49ers win by?
