Jaylen Brantley scored 11 points for the Terrapins, who bolted to a 9-0 lead and never trailed in completing a season sweep of the Buckeyes. The victory enabled Maryland (21-4, 9-3 Big Ten) to avoid its first three-game skid since 2012. Maryland outscored Ohio State 33-0 off the bench. Melo Trimble chipped in with 10 points for his 23rd double-figure scoring game of the season.
Marc Loving led the Buckeyes (15-11, 5-8) with 24 points and Jae-Sean Tate had 20. It was only the 10th time in 13 seasons under coach Thad Matta that Ohio State has been swept in the regular season by a Big Ten foe.
The Buckeyes trailed by 16 in the first half and 70-58 with 8 minutes left before cutting the gap to 77-72. Then, with the shot clock about to expire, Huerter launched a lengthy 3-pointer from the top of the key that found the bottom of the net with 2:08 to go.
Cowan clinched it with another long shot with 41 seconds remaining.
The Buckeyes closed to 56-50 with 13 minutes left on a 3-pointer by C.J. Jackson. It was 54-47 before Brantley and Cowan drained 3-pointers during a surge that upped the lead to 66-54.
Ohio State rallied once more, but couldn't complete the comeback.
Maryland shot 55 percent, made seven 3-pointers and committed only four turnovers in taking a 45-31 halftime lead.
Minutes after the school honored former coach Lefty Driesell with a banner-raising ceremony, the Terrapins kept the feel-good spirit going by keeping the Buckeyes scoreless for the opening 4 1/2 minutes.
After Ohio State closed to 16-13, Brantley scored five points in an 11-2 spurt. Not long after that, two straight dunks by Michal Cekovsky made it 40-24.
