Magic fire Jacque Vaughn

— -- The Orlando Magic have fired head coach Jacque Vaughn, general manager Rob Hennigan announced Thursday.

Vaughn, 39, was in his third year as Orlando's coach and had a 58-158 record. A former Spurs assistant coach under Gregg Popovich, Vaughn was hired to guide the Magic in their post- Dwight Howard era.

"Jacque has been a trusted friend and colleague," Hennigan said. "We thank him immensely for his contributions and sacrifices in bringing our team to this point, and we greatly appreciate his unwavering commitment to our organization. We have tremendous respect for Jacque and certainly wish him the best as he embarks on the next phase of his career."

Hennigan said assistant coach James Borrego has been named the interim coach. The team is set to hold a news conference Thursday afternoon.

The Magic dropped their 10th straight game -- and have lost 16 of their past 18 games -- with a 110-103 loss at San Antonio on Wednesday.

The most recent losing streak has included perplexing losses to some of the NBA's worst clubs in Detroit, Charlotte, New York and the L.A. Lakers.

Despite being as healthy has the Magic have been all season, the Magic have given up 100 or more points in 14 consecutive games. They've also lost five of their past six at home, where they are just 5-17 this season.

With the club essentially starting over, Orlando was patient with Vaughn while the Magic went 43-121 over his first two seasons. But as the club has improved its roster this season, the results didn't match expectations -- and the Magic have the same 15-37 record as they had through 52 games in the 2013-14 season.

The Magic's .269 win percentage over the past three seasons under Vaughn is the worst in the NBA during that span, according to ESPN Stats & Information.

Vaughn's win percentage also is the worst among Magic coaches and the second-worst in NBA history among coaches with at least 200 games. Only Sidney Lowe, who coached parts of two seasons with the Timberwolves and three seasons with the Grizzlies, has a worse win percentage.

Vaughn, who also played for the Magic during his 12-year career as a point guard, pointed toward the team's lack of chemistry as a reason for the team coming up short in Wednesday's loss to the Spurs.

"We have a first-year player [ Elfrid Payton], a second-year player [ Victor Oladipo] on the court trying to win a ballgame in the fourth quarter," Vaughn said. "[The Spurs have] done this for many years, execution-wise -- players knowing what they're going to do and who's going to get it. That's just a part of growing up and being together for the continuity for a long time."

This past offseason included the club's most extensive roster makeover since Vaughn's hire. The moves brought in eight new players, including veterans Channing Frye and Ben Gordon, to fortify a roster that already featured a young core of Oladipo and Nik Vucevic.

But the team struggled out of the gate when both Oladipo and Frye suffered preseason knee injuries.

Orlando's players have missed 89 games collectively to injury this season. The list includes Aaron Gordon, the No. 4 overall pick in the 2014 draft who just returned to action after missing 31 games with a broken left foot.

Through the injuries, Orlando has also struggled to find a cohesive lineup. Orlando used 11 different starting lineups this season.

Several league executives have speculated that former Magic player and veteran coach Scott Skiles could be a front-runner for the job.

Skiles played five of his 10 NBA seasons with the Magic, enjoying the best years of his career there. He has compiled a 443-433 career record as a head coach with Phoenix, Chicago and Milwaukee.

Borrego, who was Vaughn's lead assistant, is in his third season with the Magic, having previously worked with New Orleans and San Antonio. He was the head coach of Orlando's summer league team in 2013.
