True freshman walk-on Zack Annexstad threw two touchdown passes to Tyler Johnson in his debut, and Minnesota opened the season by overwhelming New Mexico State in a 48-10 victory.

Antoine Winfield Jr. pitched in the first punt return for a score by the Gophers in five years, a 76-yard zigzag through an Aggies coverage unit that missed six tackles on the play. That was the third of four straight touchdowns for Minnesota in the second quarter.

Annexstad completed 16 of 33 passes for 220 yards.
