Sixers rookie Arnett Moultrie received an extended opportunity to shine and took full advantage during Philadelphia’s 109-101 loss to the Boston Celtics on Tuesday night before 16,189 fans at the Wells Fargo Center.

Moultrie, the first man off the bench, delivered one of the more efficient performances of his career, finishing with 10 points on 5-for-5 shooting and four rebounds in 19½ minutes. He's 12-for-12 from the floor over his past four games.

“It’s encouraging to see him growing, which I think is a great sign, and so I hope we keep building on that,” Sixers coach Doug Collins said.

Moultrie’s performance was just one of several strong showings for the Sixers, who placed seven players in double-figure scoring for the first time this season but were undone from beyond the 3-point line. The Celtics hit 11 3s on 57.9 percent shooting while the Sixers shot 5-for-21 (23.8 percent) from long range.

Thad Young had 19 points and 10 rebounds, Evan Turner provided 18 points, nine rebounds and seven assists and Jrue Holiday added 18 points, 10 assists, five rebounds and four steals. He also had five turnovers.

But it wasn’t enough to keep the Sixers (23-36) from suffering their second consecutive loss and ninth in their last 10 games. They dropped to a season-worst 13 games under .500 and 7½ games behind Milwaukee for the eighth and final playoff seed in the Eastern Conference with 23 to play. The Bucks also own the head-to-head tiebreaker.

“It’s frustrating losing, but once again the effort was there, we communicated well,” Turner said. “And once again, it’s the little stuff that kind of broke our backs tonight.”
