Pat Haden threw touchdown passes of 11 yards to Willie Miller and three yards to John Cappelletti in the opening half and the Los Angeles Rams remained unbeaten with a 27-10 victory over the San Francisco 49ers yesterday.

The Rams, penalized 15 times for 136 yards, looked less than inspired against the hapless 49ers (1-5), but still had more than enough to improve their record to 6-0. Along with Washington and Pittsburgh, the Rams are one of three undefeated clubs.

Although tangled in a holding pattern for much of the first half, the Rams were able to build a commanding 17-3 lead.

Los Angeles was penalized five times for holding, besides clipping and tripping violations, for a walkoff of 83 yards. The 49ers, on their own, managed only 80 yards.

San Francisco got most of its penalties out of the way early, but not before contributing mightily to the Rams' first touchdown.

On the 49ers' first series, they were assessed for holding, had an illegal-formation penalty declined, then made a costly error on a punt.

They lined up improperly before Mike Connell kicked to Jackie Wallace for a short return to the Rams' 46. The next time, Wallace grabbed Connell's punt at his 42, cut between the first two 49ers downfield and raced down the left sideline to the San Francisco 15.

The Rams overcame their first holding penalty as a quarterback Pat Haden avoided Cedrick Harman's rush to hit Cullen Bryant for a 10-yard gain, then threw a three-yard pass to fullback John Cappelletti for the touchdown.

A fumble by Haden, who was blasted by Hardman at the Rams' 37, set up the 49ers' field goal. It was a 25-yarder by Ray Wersching and was the first points the Rams had yielded in the first quarter this season.

After Archie Reese fell on the fumble, the 49ers drove to a first down at the Rams' six. But tight end Paul Seal, open in the end zone, dropped Steve DeBerg's third-down pass and San Francisco settled for three points.

The Rams got that back in the second period on a 47-yard fielf goal by Frank Corral. Pushed back to their nine by holding on a San Francisco punt, the Rams marched 62 yards in 10 plays, one a 26-yard dash by Bryant for the Rams' longest longest run from scrimmage this season.

After cornerback Pat Thomas intercepted a DeBerg pass at the Rams' 42, Los-Angeles needed only six plays to score. Willie Miller, left ungarded in the end zone, took an 11-yard pass from Haden for the touchdown with 28 seconds left in the half.

Inexplicably, O.J. Simpson tried to dive over the Rams' line at his 22 and fumbled, Jim Youngblood recovering for Los Angeles. A tripping penalty against center Rich Saul pushed the Rams back and Corral missed an attempted 45-yard field goal on the final play of the half.

Jerry Latin fumbled the second-half kickoff to the 49ers' Bob Jury at the plays, the 49ers pulled to 17-10, fullback Greg Boykin covering the last two yards around left end.

Latin fumbled the next kickoff, too, but recovered it himself, at the Ram 15. With a clipping penalty tacked on, the Rams started from their five. Ninety-five yards and 12 plays later, it was 24-10 as Bryant sprinted in from the 10.

On a third-and-five play, Bryant started wide right, then suddenly cut in. The defenders were left in no position to make a tackle.

Corral kicked a 38-yard field goal in the fourth period. Connell, kicking out of ought it back within field-goal range at the 28.
