After losing the first three games of the Eastern Conference finals, Orlando has come back to win two in a row and will try to even the series when it travels to Boston for Game 6 Friday.
No team has ever won a seven-game NBA playoff series after losing the first three.
Boston sports fans have already suffered such a trauma this year. The Boston Bruins took a 3-0 lead in the Eastern Conference semifinals earlier this month before losing the series to Philadelphia. The Bruins became only the third NHL team to win the first three games and then lose a series.
Orlando took a nine-point lead into the fourth quarter and then outscored the Celtics in the final period 29-17. Lewis made three field goals and a free throw over the first 3 minutes of the quarter as Orlando was building a 91-78 advantage.
The Magic shot 52 percent from the field and limited Boston to 43 percent. Orlando grabbed 17 more rebounds than did the Celtics.
Jameer Nelson led Orlando in scoring with 24 points and Dwight Howard had 21. Lewis finished with 14.
The Celtics were led by Rasheed Wallace with 21 points. Rajon Rondo had 19 and Paul Pierce 18.
Boston center Kendrick Perkins was ejected in the final minute of the second period after picking up his second technical foul of the game. Unless the technical foul is overturned on appeal, Perkins will be suspended for Game 6.
