The former home of the Cardinals and Kurt Warner were winners in their former home city.
Arizona was in control after scoring 10 points on turnovers and adding a pair of long scoring plays on touchdowns by Tim Hightower and Jerheme Urban in a 34-13 victory on Sunday.
Arizona (5-3) ran off 31 straight points to win for only the second time in five road games and solidify its NFC West lead against a team that had been hoping to climb back into the race. The Rams (2-6) have lost two straight after winning their first two games under new coach Jim Haslett, and were booed off the field at halftime and at every opportunity thereafter before the Edward Jones Dome emptied out in the fourth quarter.
Warner was 22-for-33 for 343 yards with two touchdowns and no interceptions in only his second start in St. Louis since the Rams released him in 2004.
Steven Jackson was ineffective after missing last week’s loss at New England with a thigh injury, gaining 17 yards on seven carries and dropping a sure touchdown pass in the third quarter that prompted vociferous booing. Jackson sat out most of the second half.
Quarterback Mark Bulger led the Rams with 32 yards on three scrambles, while going 16-for-33 for 186 yards with two touchdowns and two interceptions. Torry Holt caught a 3-yard touchdown pass in the third quarter for St. Louis and had four catches for 41 yards, all in the second half.
Antrel Rolle jumped on an underthrown pass for an 40-yard interception return for a TD, the fourth of his career and second in two seasons, to get the Cardinals rolling in the second quarter. Bulger’s lost fumble on a sack by Adrian Wilson set up a field goal by Neil Rackers that put the Cardinals ahead at 10-7.
Cornerback Jonathan Wade bobbled a sure interception into the arms of Urban, who had clear sailing the last 30 yards or so of a 56-yard touchdown play that gave the Cardinals a 24-7 halftime lead. The 24-point quarter was Arizona’s first since Nov. 18, 2001 against the Lions, and their first in the second quarter since Nov. 22, 1987 at Philadelphia.
