Mike Tomczak's passing helped tailback Keith Byars score the three touchdowns that put 11th-ranked Ohio State in the Rose Bowl by beating Michigan, 21-6, yesterday in Columbus, Ohio.

Moments after the Buckeyes had won the Big Ten championship, portions of the largest Ohio Stadium crowd in history, 90,286, ran onto the field.

Byars, the nation's leading scorer and rusher going into the game, gained only 30 yards in the first half. But he scored on runs of one, two and two yards -- the final two touchdowns coming within a span of 85 seconds in the fourth quarter when the Buckeyes (9-2 overall and 7-2 in the Big Ten) blew the game open.

Bo Schembechler, suffering through his worst year as Michigan coach (6-5 and 5-4), complained that officials missed a call in the third quarter.

Michigan had first down on OSU's 19-yard when quarterback Chris Zurbrugg indicated to referee Otho Kortz that his players couldn't hear his signals. After Kortz told Zurbrugg to continue the play, right guard Bob Tabachino moved, costing his team five yards. Then Bob Bergeron missed a 37-yard field goal, enabling the Buckeyes to hold their 7-6 lead.

"On the road, an official has to protect the quarterback," Schembechler said. "They didn't help mine."
