EAST LANSING, Mich. — Taulia Tagovailoa threw for three touchdowns and ran for another and Maryland’s defense forced five turnovers Saturday as the Terrapins beat Michigan State 31-9.

It was the first time Maryland won at Michigan State since the Terrapins upset the No. 2-ranked Spartans in 1950. Maryland has won its first four games of the season by at least 18 points for the first time since 1913.

For the first time since the season opener against Towson, Maryland did not fall behind by 14-0 at the start of the game.

Tagovailoa, who completed 21 of 36 passes for 223 yards, led the Terrapins (4-0, 1-0 Big Ten) to touchdowns on three of their four first-half drives and a 21-3 halftime lead. He had scoring throws of 1 yard to Sean Greeley and 12 yards to Tyrese Chambers before plowing up the middle on a 1-yard touchdown run. Tagovailoa added a 31-yarder to Octavian Smith Jr. late in the fourth quarter.

The Spartans (2-2, 0-1) drove multiple times deep into Maryland territory, including to the 1-yard line, but were held to a 37-yard field goal by Jonathan Kim late in the second quarter and a 9-yard touchdown pass from Noah Kim to Tyrell Henry in the third quarter.

Michigan State has dropped its first two games under Harlon Barnett, who was appointed interim coach to replace Mel Tucker, who was suspended Sept. 10 pending the results of an outside investigation into a USA Today report that alleged he sexually harassed activist and rape survivor Brenda Tracy during a phone call last year. The school announced Monday that Tucker will be fired without compensation for misconduct involving Tracy.
