American Football:The San Francisco 49ers denied the Arizona Cardinals their second successive NFC West divisional title on Monday night, capitalising on their opponents' fumbling to ride out surprise 24-9 winners.
The 49ers forced seven turnovers and quarterback Alex Smith produced two touchdown passes for San Francisco, who kept alive their own slim play-off chances.
"I can't express how proud I am of our team," 49ers coach Mike Singletary said. "Most teams would have quit (and said) we're not going to make the play-offs but we came out and played well."
Smith, who has excelled since being made starting quarterback in late October, connected with Vernon Davis from five yards out and Michael Crabtree for 35 yards as the 49ers raced to a 17-0 halftime lead.
Arizona clawed back to 17-9 with 14:03 left on a one-yard scoring run from Beanie Wells, but he fumbled a few minutes later to give up possession at the Cardinals' 16-yard line.
Running back Frank Gore capitalised with a two-yard touchdown run for the 49ers and finished with 167 rushing yards.
The Cardinals (8-5) finished with five fumbles and two interceptions by Kurt Warner for a turnover total that matched the NFL season's highest. Warner had made 130 passes without an interception and went without a touchdown pass for the first time this season.
"It was one of those things where the ball didn't bounce in our direction," Warner said. "There were some instances where guys were trying to gain extra yards and at times they knew what we were doing and made good plays. It was a mistake-filled game we have to correct and move forward."
Arizona can still clinch the division by winning two of their final three games.
