"There's no excuses," Matthews said. "They played better than us for a half and we couldn't get out of the hole."
Irving led the way in the first quarter, shooting 6 of 9 while Cleveland led by as many as 11. The Cavs' lead hit its apex at 51-32 in the second quarter after Irving fed Thompson for a dunk. Portland had 12 turnovers, shot 34 percent in the first half and trailed by 17 at halftime.
Portland came out of the break more composed and made a run, with back-to-back jumpers from Aldridge, a 3-pointer from Matthews and a ferocious dunk from J.J. Hickson to cut the lead to 55-46.
Portland managed to hang around and entered the final quarter still trailing by nine. The Blazers outscored Cleveland by four in the final quarter.
NOTES: Cleveland has won 12 of the last 18 games in the series but Portland had won the past four, including 118-117 in two overtimes on Dec. 1. Irving missed that game with a broken finger. ... Detroit Lions defensive tackle Ndamukong Suh, who grew up in Portland, was in attendance.
