Harrison posted 12 points (3-13 FG, 2-10 3Pt, 4-8 FT), six rebounds, two assists and one steal across 29 minutes during Friday's 72-59 summer league loss to the Cavaliers.
Though he struggled with efficiency across the board, Harrison was the team's third-leading scorer and secured a team-high six boards. The former Kentucky product will likely have to put together better outings if he hopes to make a roster spot in Washington.
