During the 2012–13 season, Miller was inserted into the starting lineup 17 times and averaged 4.8 points per game for the season. The Heat would again advance to the NBA Finals, this time against the San Antonio Spurs. Miller was inserted into the last 4 games of the Finals to help space the floor, and scored 8 points in game 6 as the Heat barely squeaked out a victory. One highlight of the game was a three-pointer he made while wearing one shoe. The Heat won the series in game 7 on June 20, 2013, giving Miller his second championship.
