MIAMI — Every part of Mike Miller's game was on display. A perfect night from 3-point range. Diving for loose balls. Coming up limping and in obvious pain after he dove for those loose balls.
As a season debut goes, it certainly was memorable.
"Fun!" Miller tweeted afterward.
That's one way to describe his night.
Miller was 6 for 6 from the field, all those shots coming from beyond the arc, and scored 18 points in 15 minutes. Still not fully recovered from offseason surgery to repair a hernia problem, Miller helped spark a huge second-half comeback by the Miami Heat, as they rallied from down 17 points late in the first half to run away from the San Antonio Spurs 120-98 on Tuesday night.
"Every once in a while you get going when you're a shooter," Miller said. "I just happened to do that. First game back, it felt good."
His teammates were more succinct.
"You couldn't even script that any better," said Heat forward LeBron James, who led Miami with 33 points.
Miller was able to leave the arena without any visible limps or icepacks, which these days represents a major victory for the veteran swingman.
Since signing with the Heat in the summer of 2010, Miller has missed more than half the team's regular-season games and undergone four surgeries. His run of bad luck started after snapping his thumb when it got tangled in James' practice jersey during a training-camp workout last season, and he also dealt with shoulder and ankle problems over the remainder of the year.
This season, it was the hernia issue that popped up shortly before training camp, and he sat out Miami's first 12 games even though he regularly pleaded with Heat coach Erik Spoelstra that he was ready to return.
On Tuesday, Spoelstra was convinced — to a point, anyway. He planned to play Miller for no more than six minutes. Making six 3-pointers led to a change in that plan.
"I've played with this guy for four years, so this is old hat for me," Heat forward Shane Battier said. "I've seen him do this time and time again. He's one of the special shooters in the league. ... He gives us a lot more options. In a game like tonight when we needed a spark, he can give you that spark."
He can also give coaches angst.
Undeterred by his near-constant state of injury since joining the Heat, it took Miller — who got a huge roar from the sellout crowd after checking into a game for the first time this season — about two minutes before his first dive to the court on Tuesday night. By the second or third, he was limping away with some sort of lower-leg problem.
"That's who he is," Spoelstra said. "At this point, I can't cringe any more than I already do. You can't tell him to play to a different personality than what he is. That's what he's always been. You go back to his days at Florida, he played with reckless abandon. That's why you love that guy, for the hustle, the effort plays. He's relentless."
It was the 22nd time in Miller's career that he hit at least six 3-pointers, and the first time he took at least six without missing any. He was 5 for 5 from 3-point range on Feb. 17, 2010, for Washington against Minnesota.
The six 3-pointers matched his most in a Heat uniform.
Chris Bosh scored 30 points and the Heat used a historic third-quarter turnaround to erase the big deficit. Miami outscored San Antonio 39-12 in the third quarter — matching the second-largest differential for any quarter in Heat history, and matching the second-worst differential for a period in Spurs history, according to STATS LLC.
Even after a night like that, the most popular topic in the Heat locker room was Miller's return.
"The fans, from Day 1, have been amazing to me," Miller said. "Last year when I came back, it was the same thing."
He said he and the Heat have worked out an arrangement. If they don't ask him about any injuries, he won't tell them.
"I'm not going to do another X-ray," Miller said. "Anything that comes in an X-ray is bad news. So they know my stance right now and I'm going to continue to play."
