In the days leading up to the Eastern Conference finals, Heat big man Chris Andersen worked constantly on spacing the floor inside the paint to provide an extra option for driving teammates.

On Wednesday in Game 1, Andersen’s extra work paid off.

The Heat scored 60 points in the paint in its 103-102 overtime victory against the Indiana Pacers, and Andersen set a career-postseason high with 16 points. In addition to the personal milestone, Andersen also set a Heat postseason record for most field goals without a miss. Andersen went 7 of 7 from the field, breaking Alonzo Mourning’s record of six field goals without a miss.

“To be mentioned with Alonzo Mourning, it’s an honor, but at the same time my main focus is the Indiana Pacers and trying to get to that championship,” Andersen said.

Andersen was signed midseason mainly for his defense and tireless work ethic, but his ability to catch the ball in traffic has been a significant aspect of the Heat’s overall offensive game.

Andersen is 29 of 35 from the field this postseason, with the majority of his points coming on drive-and-pass situations near the rim.

“It’s been engrained in my head from the coaches the last two weeks to stay on the baseline and keep the paint open for whenever our drivers get into the lane, and they’re able to make the decision to dump it off, score or kick it out [for] the three-pointers,” Andersen said. “I just try to find the right space and the right position to be in to be able to get those easy baskets.”

As for his efficient numbers, Andersen said he wasn’t even aware of his offensive statistics until a reporter pointed them out Thursday.

“Is that what I’m shooting? OK then,” Andersen said. “I don’t even think about that. I just basically take what the defense is giving me.”
