Ohio State quaterback Art Schlichter accounted for four touchdowns today and the Buckeyes, off to their best start since 1975, rolled over Michigan State, 42-0.

The fourth-ranked Buckeyes (8-0) barely extended themselves in routing the fading Spartans.

Michigan State won its first three games but now has lost five in a row.

Schlichter, a 6-foot-2 200-pound sophomore, showed today why he well may be the best all-around quarterback in college football. He passed for touchdowns of 53 and 12 yards to Doug Donley and ran for two on jaunts of three and six yards.

Schlichter completed eight of 16 passes for 154 yards and ran nine times for 33 yards. He did it all in a little more than 2 1/2 quarters.

An Ohio Stadium homecoming crowd of 87,747 was treated to the third straight game in which the Buckeye offense has rolled up more than 500 yards. OSU accounted for 533 yards today while limiting Michigan State to 147.

Spartan quarterback Bryan Clark, son of Detroit Lion Coach Monte Clark, had a dreadful day, completing only six of 21 passes with two interceptions.

The Spartans had only two real scoring opportunities and one of those was a 67-yard field goal attempt.

Down, 28-0, at the half, Michigan State got its best chance to score early in the third period. Cornerback Jim Burroughs burst through and blocked an Ohio State punt with the Spartans recovering at the Buckeye eight.

Four plays later they were still at the eight.

Ohio State took over on downs and Schlichter took the Buckeyes on a 92-yard, 15 play drive. He scored the touchdown himself on a six-yard run, running over two would-be tacklers at the two-yard line.

Michigan State's best play of the day didn't even count. A 90-yard punt by Ray Stachowicz was called back because of an illegal Spartan substitution.

Nine Ohio State runners gained yards with fullback Rick Volley leading the way with 132 in 17 carries. He scored on a 32-yard dash.
