After losing four starters from a squad that reached the Sweet 16, the Terrapins opened a new season with a lackluster performance. Coach Mark Turgeon has a 16-man roster containing nine freshmen, and he spent much of the game looking for the right combination.
American led 47-43 with 7:34 remaining before Maryland finally played to form. Trimble -- the lone returning starter -- made two baskets in the lane to spark a 7-0 run.
AU closed to 57-54 before Trimble made a driving layup with just over a minute left.
Mark Gasperini scored 14 points for the Eagles, who finished 12-19 last season and are picked to finish in the middle of the Patriot League. On this night, however, AU gave Maryland all it could handle in a duel between Washington area teams.
Turgeon started two freshmen, Cowan and Huerter. The lone senior in the starting lineup was 6-foot-11 center Damonte Dodd, who had two fouls in his 2 minutes of playing time in the first half.
Trimble had 13 points on 5-for-8 shooting to stake the Terrapins to a 31-25 halftime lead.
Maryland led 16-11 before the Eagles got eight points from Leon Tolksdorf in a 12-2 run.
After Turgeon called a timeout, the Terps rattled off 10 straight points. Cowan started the surge with a 3-pointer, two free throws and a three-point play.
