Celtics sign Aron Baynes

The Celtics have signed free agent center Aron Baynes.

“We are thrilled to have Aron aboard,” said Celtics president of basketball operations Danny Ainge. “He’s a great teammate, a hard worker and provides us some needed strength and toughness on the interior.”

A five-year NBA veteran with San Antonio and Detroit, Baynes (6-10, 260 lbs) has averaged 5.2 points (51.4% FG, 81.1% FT), 4.1 rebounds and 14.1 minutes in 295 career games (24 starts). He’s averaged at least 4.4 rebounds and 1.5 offensive boards in each of the last three seasons.

In 75 games (two starts) with the Pistons in 2016-17, Baynes, 30, averaged 4.9 points (51.3% FG, 84.0% FT) and 4.4 rebounds in 15.5 minutes. He scored a season-high 20 points (8-13 FG) against Oklahoma City on Nov. 14, and hauled in a career-high 17 rebounds to go along with 13 points against Phoenix on March 19. The Washington State University product recorded two double-doubles last season.

Baynes has made four postseason appearances in his five-year NBA career, and was a member of the Spurs team that won an NBA Championship in 2013-14. He played in 14 playoff games that year, including a 10-point performance in Game 1 of the Western Conference Semifinals against Portland.
