Celtics 90, Trail Blazers 89

PORTLAND, Ore. — Guard Evan Turner’s 3-point shot with one second left gave the Boston Celtics a 90-89 victory over the Portland Trail Blazers on Thursday night at the Moda Center.

Guard Avery Bradley scored 18 points, and forward Jared Sullinger had 17 points and nine rebounds for the Celtics, who snapped a three-game losing streak.

Guard Damian Lillard finished with 21 points, seven assists and six rebounds for the Trail Blazers, who lost for the fifth time in six games. Portland guard Wesley Matthews scored 16 of his 18 points in the second half.

Portland (31-13) trailed only 44-42 at the half despite 1-for-10 shooting from 3-point range. Blazers center Chris Kaman had 12 of his 13 points before halftime, sinking six of eight shots from the field.

However, Portland caught fire from beyond the arc in the third quarter, knocking down seven of 11 attempts.

Matthews sank four consecutive threes to push Portland in front 56-52 with 6:55 left in the third quarter. Boston (14-26) rallied to go back ahead 66-65 on a Bradley drive late in the quarter, but the Blazers carried a 72-67 advantage heading into the final period.

Lillard’s fall-back jumper increased Portland’s lead to 84-77 with 5:35 remaining, but the Celtics scored four straight to cut the margin to 84-81 with 4:55 left.

Lillard hit a 3-pointer to make it 87-81, but Sullinger converted from close to range to cut the difference to 87-83, and Bradley’s 18-footer made it 87-85 with 2:21 to go. Sullinger’s rebound basket tied it at 87-87 with 1:56 to play.

Matthews sank one of two at the line to give Portland an 88-87 lead with 1:15 remaining.

Neither team scored again until forward Thomas Robinson made one of two free-throw attempts to give the Blazers an 89-87 advantage with 26.6 seconds left.

After a Boston timeout, Sullinger missed a 3-pointer, but the Celtics rebounded and called timeout again with 8.5 seconds left. The Celtics inbounded, and the ball was knocked out of Sullinger’s hands. In the scramble for the ball, Sullinger fished it out and whipped it to Turner, who swished his shot.

After a Portland timeout, the Blazers were unable to get a shot off before the horn sounded.

Boston led throughout most of the first quarter, taking a 23-19 advantage into the second period.

The Celtics’ edge was 38-33 when the Blazers went on a 6-0 run to jump on top 39-38. It stayed close through the rest of the quarter, with Boston in front by two points at intermission.

NOTES: Portland LaMarcus Aldridge will have surgery on a torn ligament in his left thumb later this week and will be out six to eight weeks. Aldridge was hurt Monday in Portland’s 98-94 win over the Sacramento Kings, and a second MRI confirmed Thursday that he has a radial collateral ligament tear in the thumb. … Neither Aldridge nor G Damian Lillard was voted as a starter for the Western Conference for the All-Star Game, though Lillard could make the team as a reserve. … Without traded veterans G Rajon Rondo and F Jeff Green, Boston coach Brad Stevens is looking elsewhere for on-court leadership, including F Gerald Wallace and newly acquired F Tayshaun Prince. “It puts more on the guys in the locker room to become older than they are in some ways,” Stevens said.
