Orlando, FL (SportsNetwork.com) - Tobias Harris scored 19 points, Kyle O'Quinn and Nikola Vucevic each recorded double-doubles, and the Orlando Magic fended off the Boston Celtics, 100-95, on Tuesday.

The Magic won despite nearly blowing a 27-point lead in the fourth quarter. They were held to 15 points over the last 10 minutes, but did just enough to snap a four-game slide.

O'Quinn and Vucevic each provided 18 points and combined for 25 rebounds.

"We let up...but we somehow found a way," O'Quinn said.

Tyler Zeller scored 22 points and grabbed 10 rebounds to pace the Celtics, who have dropped two in a row on the heels of a three-game winning streak.

Jameer Nelson, playing his first game as a visitor in Orlando, finished with nine points and 11 assists and was vital in Boston's near comeback.

Nelson made a 3-pointer and assisted on five other baskets during a 27-3 run that trimmed a 27-point deficit down to three, 90-87, coming down the stretch.

"He spurred us on and fired us up," Zeller said of Nelson.

His pinpoint, left-handed dish to a cutting Zeller led to a layup and pulled the Celtics within 90-84, and the Magic called a momentum-killing timeout with 2:34 left after Kelly Olynyk made a 3-pointer in transition.

Harris, who was questionable with a finger injury coming in, spun in a tough fadeaway in the lane coming out of the break, and O'Quinn made two from the foul line the next time down for a 94-87 Magic lead.

Orlando missed three free throws in the final 37.3 seconds, but nonetheless came away victorious.

The Celtics' first quarter was summed up when they forced a turnover and had numbers going the other way. Evan Turner coughed the ball up at midcourt, and Vucevic threw down an alley-oop dunk at the other end.

The sequence was part of a 20-4 run to open the game, and the Celtics wound up scoring an embarrassing nine points in the first quarter on 2-of-22 (9.1 percent) shooting.

An Evan Fournier runner four minutes into the second stretched Orlando's lead to 40-15, and it was a 53-30 spread at the break.

The lead never dipped below 19 in the third quarter.
