The Terps won their first bowl game since 2010 in Mike Locksley's third year at the helm.
The Terps had multiple opportunities deep in the Spartans' territory, but often came away empty-handed in a game Maryland played from behind in its entirety.
Since Taulia Tagovailoa became the starting quarterback last season, the Terps have won every game in which he eclipses 300 passing yards.
With injuries ravaging the position, Carriere's eight catches, 134 yards and two touchdowns gave the Terps confidence in their new No. 2 wideout.
The Terps also secured wide receiver Marcus Fleming as a transfer from Nebraska.
