Despite Clarence Trent's hot shooting hand -- he connected on two three-pointers and another jumper in the first seven minutes -- the Redhawks (3-3) fell behind early as Eastern (5-2) opened the game with a 19-8 run.
Seattle U rallied behind sophomore forward Deshaun Sunderhaus, who came off the bench to score nine of the the team's final 12 points in the first half, and the Redhawks went into the break trailing 38-35.
Junior forward Shore Adenekan and junior guard Jarell Flora sparked the Redhawks' next run, a 12-2 spurt to open the second half that put Seattle U in front. Eastern Washington sophomores Venky Jois and Tyler Harvey brought the Eagles back, and with five minutes remaining the score was tied at 67.
Harvey then hit a three to put Eastern on top, a lead they wouldn't give up the rest of the way. Turnovers, missed shots and the Eagles' clutch free-throw shooting cost Seattle U down the stretch as their comeback attempt fell short.
Junior point guard Isiah Umipig led SU with 16 points and seven assists, while Trent added 15 points, five rebounds, two steals and two blocks. Trent, who came into the game shooting 25 percent from three-point range, also went 3-for-6 beyond the arc. Adenekan and Sunderhaus each scored 13 points, and Flora chipped in 10 to give the Redhawks five double-figure scorers.
Harvey led EWU with a career-high 30 points, while Jois had 19 points, 10 rebounds, three blocks and two steals.
The Redhawks have now lost all three of their road games this season -- at Washington, at Boise State, at Eastern Washington -- while going undefeated at home against Cal State Fullerton, Evergreen State and UC Riverside. SU's next game is at home on Monday, Dec. 2, against UC Davis.
