BLOOMINGTON, Indiana (Ticker) -- Michigan State gave Morris Watts a victory in his first game as interim coach.
The Spartans erupted for 35 unanswered points in the second quarter and snapped a four-game losing streak with a 56-21 Big Ten Conference victory over Indiana.
Damon Dowdell threw a pair of touchdown passes and Jaren Hayes rushed for two scores in the second-period blitz that enabled the Spartans (4-6, 2-4) to open a 42-7 lead at the intermission.
The 63-year-old Watts, Michigan State's offensive coordinator, was named interim coach earlier in the week after Bobby Williams was fired with his program in turmoil.
Michigan State has been plagued by numerous off-the-field problems this season and was coming off a 49-3 loss to Michigan, its worst defeat since 1947.
With the suspended Jeff Smoker having entered a substance abuse program, Dowdell likely will finish the year as the Spartans' starting quarterback.
He earned his first career win Saturday, completing 17-of-25 passes for 203 yards and four touchdowns. He also tossed TD strikes to Charles Rogers and Jason Randall in the third quarter, when the Spartans extended their advantage to 56-7.
David Richard paced Michigan State on the ground with 136 yards and a touchdown on 20 carries. Rogers caught five passes for 102 yards and a pair of TDs.
Gibran Hamdan completed just 11-of-25 passes for only 100 yards with a pair of interceptions for the Hoosiers (3-7, 1-5), who suffered their fourth straight loss.
Michigan State increased its lead in the all-time series to 35-13-2 and retained the "Old Brass Spittoon," which is awarded to the winner.
