Marc Bulger shook off another beating to pass for 155 yards and an early touchdown to Torry Holt, and the St. Louis defense was solid until the final seconds today in a 13-9 victory over the 49ers, who lost their eighth straight.

Bulger was sacked six times by the 49ers, who also sacked him six times in the clubs' first meeting. The Rams couldn't score a touchdown after their opening drive, but the defense had little trouble with San Francisco's league-worst offense until two desperate fourth-quarter drives.

After floundering all afternoon, the 49ers (2-8) drove 68 yards in the final 1:28 to the St. Louis 21. But with 3 seconds to play, Trent Dilfer's final pass was intercepted at the goal line by Oshiomogho Atogwe.

After the longest winless start in the franchise's 70-year history, the Rams (2-8) have won both outings with Steven Jackson back in good health. The star running back had 92 persistent yards in his second full game after missing four weeks with a torn groin muscle and most of another game with a bulging disk in his back.

Dilfer passed for 231 yards — 141 in the fourth quarter — while filling in for Alex Smith as the 49ers slid into their longest losing streak since 1999. San Francisco hasn't won since its trip to St. Louis in mid-September, and hasn't scored a touchdown since the opening drive of its loss in Atlanta two weeks ago.
