The Orlando Magic  came to play Monday night in Game 4 after being embarrassed in Game 3 and made a point of showing it early on.
They took a 51-47 lead at halftime over the Celtics , amazingly their first such lead after 24 minutes in the series so far.
Orlando, which shot 61.5 percent in the first quarter, built their largest lead of the game at 10 points, 42-32, with 5:47 left in the second quarter.
The Magic were led by Dwight Howard , with 17 points and six rebounds.
The other thing to keep a close eye on in the second half is the condition of Rajon Rondo , who left with a minute to go with trainer Bryan Doo to treat muscle spasms in his right leg.
