GLENDALE, Ariz. (AP) -- Janoris Jenkins became the first player in Rams history and the first NFL rookie since 1960 to return two interceptions for touchdowns in the same game and St. Louis dominated the second half to hand the Arizona Cardinals their seventh loss in a row, 31-17 on Sunday.
Arizona rookie Ryan Lindley was intercepted four times in his first NFL start.
Jenkins' returns of 36 and 39 yards emphatically ended the Rams' streak of five straight games without an opponent turnover.
Sam Bradford had a pair of 37-yard touchdown passes - to Lance Kendricks and Chris Givens - for the Rams (4-6-1), who snapped a five-game winless streak and beat Arizona (4-7) for the second time this season.
The Rams' Steven Jackson rushed for 139 yards in 24 carries.
