HOUSTON -- The Utah Jazz understand how to finish games. It's the starts that need some work.
Paul Millsap scored 12 of his 27 points in overtime and the Jazz rallied from another double-digit deficit in a 103-99 win over the slumping Houston Rockets on Saturday night.
Al Jefferson had 24 points and 13 rebounds and C.J. Miles added 16 points for the Jazz, who have come back to win 12 times this season after trailing by at least 10 points.
"It shows we've got a lot of heart, and we've got a lot of guys who don't want to lose on this team," said Millsap, who scored 11 in the fourth quarter. "But we've got to focus in and get off to better starts if we want to progress through this season."
Deron Williams went 5 for 16 from the field but dished out 15 assists.
The Jazz mustered only 19 points in each of the first two quarters and trailed by 14 at halftime. Utah then held Houston to 13 field goals the rest of the way to close the gap.
"We played a lot harder defensively in the second half," Williams said. "We took a step forward as a team. In the second half, we got after them more and didn't let them get easy baskets."
Luis Scola had 24 points and 10 rebounds and Kevin Martin scored 20 for the Rockets, who have lost five in a row, their longest skid since an 0-5 start.
"Same problems we were having early in the season, we have now," Scola said. "It's frustrating. We deserved to win this game, but we didn't know how to close it out."
Millsap scored only four points through the first three quarters, then led Utah's final push in the fourth. He hit two free throws and scored three baskets inside to tie it 86-all with 1:29 left. He was fouled by Brad Miller on a layup and made the free throw to give the Jazz their first lead.
Millsap hit nine of his last 12 shots after starting 2 for 8.
"They were leaving me open and Deron was getting me the ball," Millsap said. "We all get a feeling like that every now and then, where you feel like you're not going to miss."
Utah led 89-87 when Martin hit a pair of free throws with 27 seconds left to tie it again. Millsap missed an off-balance jumper and Shane Battier rebounded with 2.8 seconds remaining.
The Jazz knocked the ball away from Martin and out of bounds with 0.2 showing on the clock. Kyle Lowry missed a desperation shot as regulation time expired.
Millsap swished three straight jumpers from the free throw line in the extra period to give Utah control. Scola flipped in a hook shot with 34 seconds to go, but Millsap sneaked inside for a layup to put the game away.
"I don't want to be disrespectful to them," Scola said of Utah. "I really, really respect their team. But I believe today's game, it was all on us."
The Rockets went 3 for 25 from 3-point range and shot 38 percent (34 of 90) overall.

Jefferson scored the first five points of the second half while the Rockets came out cold, missing six of their first seven shots.
