Miami’s practice ends Tuesday for everybody but Shane Battier. He does what he always does, what he has since he played at Duke. Over and over he sprints, catches the ball and shoots, trying to simulate game conditions on the emptying AmericanAirlines Arena court.

“That routine, I’ve been doing it forever,” Battier says when he finally finishes. “As long as I can remember, post-practice. It’s my church in a lot of ways. It’s my time to think, my time to get my game right. And if I get put in the game I know I put in my time.”

Battier wasn’t put in Game 1 on Sunday against the Charlotte Bobcats. He also sat out one playoff game last season. On neither occasion was he injured. In Game 7 of the 2012-13 finals he hit six 3-pointers against San Antonio.

Miami’s rotation is mysterious, and it works.

“That’s sort of the situation you’re put in,” Battier says about sitting out. “You know, you can kick the can down the street and feel bad for yourself or support teammates and stay ready. I played this long. I always prepared. So I’m not going to stop now in the final two months of my career,”

Battier is 35 and this season is his 12th.

Are you saying there won’t be a 13th?

“These are probably the final couple months or weeks of my career,” Battier says. “I enjoy the competition, I enjoy the locker room. I don’t enjoy the grind as much as I used to. Part of that is having kids (ages 6 and 3) and having a family.”

Battier averages four points and 2.8 blocks this season, and 8.6 points, 4.2 rebounds and 1.8 assists for his career.
