SANTA CLARA -- Running back Frank Gore said the 49ers need to maintain their balanced approach as they make their postseason push.

After three straight games with less than 50 rushing yards, Gore topped that total with a single carry in Sunday's 19-17 win against the Seahawks when he raced 51 yards on a fourth-quarter run to set up Phil Dawson's game-winning field goal.

Gore finished with 110 yards on 17 carries. It was his third 100-yard rushing game of the season and first since going for 101 yards in a Week 6 win over Arizona. The 49ers are 3-0 when he tops the century mark and all three games have come against NFC West foes.

Gore said "it'll be big" to keep the running game going.

"I feel like we've got to stay balanced," Gore said. "When we do that, we'll be fine in the postseason."

Gore has 931 rushing yards this season, putting him 69 away from adding to his team record with a seventh 1,000-yard season. His eight rushing touchdowns this year is tied for the second-highest single-season total of his career. He ran for 10 scores in 2009.
