SAN FRANCISCO — The Arizona Cardinals threw away a chance to clinch a second straight NFC West crown.

Alex Smith threw touchdown passes after two of Arizona’s seven turnovers, Frank Gore ran for 167 yards and another score and the San Francisco 49ers kept their slim playoff hopes alive with a dominant 24-9 victory Monday night.

With a relentless defensive attack, San Francisco forced the sloppy Cardinals into five first-half turnovers and kept Kurt Warner from finding a groove. Warner threw two interceptions in the opening half after going 130 passes without a pick. Now, Arizona (8-5) can still clinch the division by winning two of its final three games.
