GLENDALE, Ariz. -- On an almost perfect Monday night for Alex Smith, the San Francisco 49ers flexed their NFC West dominance with a 24-3 flattening of the Arizona Cardinals.
Smith completed 18 of 19 passes for 232 yards and three touchdowns -- two to Michael Crabtree and one to Randy Moss -- as San Francisco (6-2) opened a two-game lead in the division and sent Arizona (4-4) to its fourth consecutive loss.
Smith's only incompletion was dropped by a wide-open receiver.
Smith was 14 of 15 for 146 yards and two touchdowns, both to Crabtree, to help the 49ers build a 17-0 halftime lead.
