Coming off a comfortable win over Stony Brook on Friday, Maryland yielded the game's first basket before Wiley drilled successive 3-pointers to spark a 12-0 run.
Maryland shot 70 percent (14 for 20) from the floor in the first half and forced nine turnovers, including four by freshman Cameron Bacote.
Bacote led UMES (1-1) with 18 points. He had 28 points and 11 rebounds in the Hawks' opener against Valley Forge.
The Terrapins are 18-0 against UMES in a series that began in 1979. This was the first game between the teams since 2015.
