SALT LAKE CITY -- Portland's Damian Lillard just needed to make one shot to get going.
Once he saw that go down, he went on a fourth-quarter scoring flurry.
"That first 3 felt real good," Lillard said. "Once that went down, I felt if I got another clean look, I'm gonna raise up again. And then it happened a couple more times."
"On the offensive end, I need to tell my teammates what's coming. As a point guard, you're the head of the team," Lillard said.
But even the second-year guard didn't know when his offense would start flowing.
When it finally did, the Jazz had no answer.
Wesley Matthews had 21 points, LaMarcus Aldridge had 18 points and 14 rebounds -- his 40th double-double -- and Nicolas Batum added 15 points to keep Portland in the race to host a first-round playoff series.
Derrick Favors scored 21 points and Enes Kanter had 15 points and 13 rebounds, but the Jazz have lost eight of nine.
Early in the fourth quarter, the Jazz led by two and Lillard hadn't converted a single field goal.
Over the next 3:24, Lillard made four 3-pointers and a pair of free throws.
"We closed out with our hands down," Utah coach Ty Corbin said. "But give them credit, they made plays down the stretch."
After that, the Blazers led by double-digits for the first time at 96-85 with 6:28 remaining and soon earned their seventh victory in their past eight games.
"He hit those 3s and he just kind of felt it. Those 3s really turned the momentum of the game," Portland coach Terry Stotts said. "Damian just took it on himself to make something happen."
Marvin Williams was out with a knee bruise and the Jazz started the five players that figure to be the core as they rebuild.
The quintet -- Gordon Hayward, Favors, Kanter, Trey Burke and Alec Burks -- are all 23 years or younger and have gained experience during this often-frustrating season for a franchise that once made the playoffs 20 years in a row.
Burks has primarily filled the sixth-man role while veteran Richard Jefferson had been the only Utah player to start (and play) every game this season.
The youthful lineup paid dividends early, but the Jazz struggled in the critical moments against a better team as they have all season. Burks had 16, Burke had 14 points and 11 assists and Hayward added 14, but no one could stop Lillard when he was determined to score in the final period.
The Blazers drew within a half game of Houston for the fourth slot in the Western Conference as Minnesota edged the Rockets 112-110 on Friday.
"You always want home court. If we can get it, we definitely want it. We saw Houston lost so that helps our chances," Aldridge said.
Portland won its final road game of the season and has two remaining at home. The Blazers swept the Jazz for the first time in franchise history.
The Blazers' defense had improved over the past few months but the Jazz got the shots they wanted, for the most part, until Portland clamped down in the fourth and scored 35 points on the other end.
"We just knew we had to take care of business. We got locked in and played better defense. It was just an understanding," Aldridge said.
The Blazers went 7 for 8 from beyond the arc in the final period and though they were outrebounded by a 47-41 margin, Portland grabbed four offensive rebounds to get second shots down the stretch.
"We're coming together at the right time. Defensively we've been locked in and our offense is starting to come around again. We're looking forward to the playoffs," Stotts said.
The Jazz led most of the first half before Matthews scored 10 points in the final 3:09 of the second period to lift the Blazers to a 53-51 advantage at the break.
Rudy Gobert was accidentally backhanded in the face by Burks as they pursued a rebound in the second quarter. ... Lillard, who was already frustrated and had not scored at that point, got whacked in the chin in the fourth quarter by Hayward's head. ... Utah is 1-30 against Western Conference opponents this season when scoring fewer than 100 points. ... In his eighth start of the season, Burks played a career-high 42 minutes.
