Rams Top Raiders in Overtime : Pro football: Zendejas’ 29-yard field goal produces a 19-16 exhibition victory. Dupree gains 100 yards, Dickerson one.

It figured that the Rams and Raiders, who took a decade to get together for this first intra-Los Angeles exhibition, would go ahead and take almost as long to actually finish the game.

It was quite an exhibition, all right, almost four hours long.

But at least the overtime period was handled crisply.

Tony Zendejas kicked a 29-yard field goal on the first possession of overtime as the Rams scored a 19-16 victory before 56,511 at Anaheim Stadium on Saturday night.

Rookie quarterback T.J. Rubley, taking over at the Raider 20-yard line, took the Rams to the Raider 12, the big plays a 25-yard pass to Jeff Chadwick and an 11-yard burst to the Raider 12 by running back Marcus Dupree.

Rubley, who played from the third quarter on, completed 15 of 23 passes for 128 yards.

By the time that Rubley, Ram running back Marcus Dupree, who had his best performance in his two-year comeback with 100 yards in 22 carries, and Raider quarterback Todd Marinovich, running a last-minute drive reminiscent of his USC days, could enliven the game during the second half, the game was limping toward the three-hour mark.

The game looked as if it was finally won when Dupree’s rushing led the Rams deep into Raider territory. The drive started with almost nine minutes left and ate up almost that much.

During the drive, quarterbacked by Rubley, Dupree carried nine times for 44 yards, and with the depleted state of the Ram running backs--Cleveland Gary and Robert Delpino were sidelined because of minor injuries--gained stature in the eyes of Coach Chuck Knox.

“As the game went on, I got stronger,” Dupree said. “I saw Walter (Payton, formerly of the Chicago Bears), and as the game went on, he got stronger. I’ve tried to pattern after him.”

Zendejas put the Rams ahead with 54 seconds left with his third field goal of the night, from 26 yards out. The Rams went 71 yards on the drive in 16 plays.

The game wasn’t won, however, because of Marinovich and a 42-yard kickoff return by Stefon Adams.

The Raiders had the ball on their 42 with 46 seconds remaining. But looking poised and comfortable in the pocket running the hurry-up offense, Marinovich completed back to back passes to move the Raiders to the Ram 15-yard line with 15 seconds to play.

The Raiders moved to the Ram eight-yard line before Jeff Jaeger’s 25-yard field goal with three seconds remaining sent the game into overtime.

The teams committed a combined three turnovers and seven penalties during the first half and five penalties were called before the third actual play of the second half.

There were nine penalties, seven against the Rams, and three points during the third quarter.

Five plays--and two penalties--into the game, Ram end Gerald Robinson swiped Raider quarterback Jay Schroeder’s arm deep in Raider territory.

The ball bounced to the Raider goal line, where Ram linebacker Kevin Greene outdived Raider tackle Bruce Wilkerson for the ball and a touchdown.

Three plays later, Schroeder teamed with Willie Gault for a 69-yard touchdown pass. Gault caught six passes for 119 yards in the game.

Though Coach Art Shell stressed during the week that his running game needed to show more life, the Raiders gained only 11 yards in nine carries during the first half. And that was before Eric Dickerson came into the game during the second half, gaining only one yard in five carries.

Late in the second quarter, Schroeder, with the Rams ahead by 10-7, forced a pass into the right corner of the end zone and into the hands of cornerback Robert Bailey.

Schroeder had tight end David Jones streaking to the right side of the end zone, but never saw Bailey.

In his up-and-down half of play, Schroeder completed 15 of his 27 pass attempts for 214 yards and was sacked twice.

The Rams took their 10-7 lead when quarterback Jim Everett finished off his night by guiding a 15-play, 70-yard drive during the second quarter that was free of both penalties and turnovers.

Zendejas then kicked a 24-yard field goal.

Early in the third quarter, the Raiders forced a fumble on a sack deep in Ram territory.

End Anthony Smith knocked the ball from rookie quarterback T.J. Rubley’s hands, defensive tackle Nolan Harrison recovered it at the Ram six, and four plays later Jaeger tied the score, 10-10, with a 28-yard field goal.

The rest of the game was a battle of field goals.
