If they play as they did Friday, that time will be a lot more bearable.
Three of the Rockets' six losses this season had come by four or fewer points, with one coming in overtime.
"It was big for us to finally win one of these games," said Miller, who scored seven of his 14 second-half points during the Rockets' game-clinching, 18-8 fourth-quarter run.
"Our six losses have been a lot like this. We've had the lead with five minutes to go, or three minutes to go. It's just figuring out how to win one. All of our games have been similar, we just finally did the right things at the end."
Miller had 23 points and eight rebounds, while Scola added 16 points.
Yao, who sustained a sprained left ankle in the Rockets' loss to Washington on Wednesday, is expected to miss at least a week, the team announced Thursday. He returned to Houston from Indianapolis to begin rehabilitation.
"We can't worry about who isn't here," Rockets coach Rick Adelman said. "We've gone without Yao for a year and a half."
"They're a very talented team," Pacers coach Jim O'Brien said. "They're used to playing without Yao. I think it's fools' gold if somebody is out of the game [to think] you have an edge."
"We couldn't get stops when we needed to," Dunleavy said. "We let them get away and we just couldn't keep up with them. We never got into our tempo or our rhythm. We had a lot of breakdowns on both sides of the ball."
The Pacers, after shooting 64.4 percent in a victory over Denver on Tuesday -- including 20 of 21 in the third quarter while scoring a franchise-record 54 points -- didn't start or finish as hot on Friday. Indiana shot 45 percent.
Indiana trailed 73-63 with four minutes in the third period, but rallied to tie it at 78 after three quarters on Posey's 3-pointer with 10.5 seconds remaining. Indiana made 5-of-6 3-pointers during the tying run, which spanned the final 3:32 of the third quarter.
Martin's 3-pointer gave Houston a 97-93 lead with 3 minutes remaining, and his 15-footer from the baseline with a minute to go gave Houston a 102-97 lead.
"We needed that confidence just because of how we've been in every game and not been able to pull them off," Martin said. "Tonight we just played together and the right way down the stretch. I think we really just buckled down and said, 'We're going to close this one out.'
"It kind of just came from within. Coach talked about mental toughness and that's what we had tonight."
Indiana had a final chance to tie, but Collison's 3-point attempt with 3 seconds remaining bounced off the rim.
