Chicago Bulls' Ben Wallace, top, battles for a rebound with Portland Trail Blazers' LaMarcus Aldridge during the first quarter.

CHICAGO — Jarrett Jack drove for a go-ahead basket and converted a three-point play with 19 seconds left in the second overtime Thursday night and the Portland Trail Blazers outlasted the Chicago Bulls 115-109 for their 15th win in 16 games.

Brandon Roy had 25 points and Travis Outlaw 21 for Portland, now 2-0 since its 13-game winning streak was ended on Monday by Utah.

Ben Gordon scored 32 points to lead the Bulls and veteran Joe Smith added a season-high 31 as Chicago dropped to 3-2 since Jim Boylan was appointed interim coach after the firing of Scott Skiles.

With the game tied in the second overtime, Gordon lost the ball as he was dribbling to set up a shot, Jack picked it up after it was tipped and drove for a go-ahead layup and was fouled. His free throw put the Trail Blazers up 111-108.

Smith just missed an attempt from in front of the basket, was fouled on the play and hit the first free throw but missed the second with 14 seconds to go.

Portland rebounded and James Jones sealed the exhausting victory by making four free throws down the stretch.

NUGGETS 80, SPURS 77: At Denver, Kenyon Martin scored underneath with 45 seconds left after Anthony Carter stole the ball from Tim Duncan and Denver turned away San Antonio.

Martin, who had missed four of five games since straining his right hamstring on Dec. 20, then rejected Tony Parker at the other end for his seventh block, and Allen Iverson sank two free throws with 6.6 seconds left to give the Nuggets a three-point lead.

After a timeout, Michael Finley was off-target on a contested 3-pointer that would have tied it.

Iverson scored 29 points and Carmelo Anthony added 17 for the Nuggets.

Parker and Duncan scored 20 points for San Antonio and Finley added 18.

SUNS 104, SUPERSONICS 96: At Phoenix, Amare Stoudemire scored 34 points while adding 11 rebounds as the Suns came back from 33-13 down in the first quarter.

Rookie Kevin Durant led the SuperSonics with 28 points.
