Michal Cekovsky delivered 10 of his 17 points during an 18-2 run that gave the Terrapins a 50-34 lead against the weary Golden Gophers, who could not summon the energy to make a comeback.
Maryland (15-6, 4-4 Big Ten) snapped a two-game skid and improved to 12-1 at home. Cowan did his part by distributing the ball and scoring all 15 of his points over the final 12 minutes.
Jordan Murphy had 19 points and 14 rebounds for Minnesota, his nation-leading 19th double-double of the season. The Golden Gophers are in the middle of a stretch of three games over six days, concluding with a matchup against No. 22 Ohio State in New York on Saturday afternoon.
Minnesota (14-7, 3-5) finished 23 for 64 (36 percent) from the floor and made only three baskets in the opening 10 minutes of the second half.
The Golden Gophers led 32-29 before Huerter hit a 3-pointer to spark the decisive run. The 7-foot-1 Cekovsky followed with the first of his five dunks in a span of just over 5 minutes, most of them on alley-oop passes from his guards.
With Huerter leading the way, Maryland made 10 of its first 12 field-goal tries after halftime.
In the first half, the Terrapins trailed 16-10 before Huerter scored eight points in a 13-0 run. It was 29-21 before Minnesota rattled off seven straight points to end the half.
Maryland will be back in action Monday for a matchup at Indiana. Tipoff on FS1 is slated for 7:00 pm.
- Anthony Cowan Jr. posted his second career double-double (15 points, 10 assists) in the win, the most assists in a game by a Terp since Melo Trimble tallied 10 against Princeton on December 19, 2015.
