The Celtics appreciate Aron Baynes’ hustle. Maybe even his hairstyle. And yesterday, the Celtics re-signed the center to a reported two-year, $11 million contract.

Baynes, 31, started in 67 of his 81 games played during his first season with the Celtics in 2017-18, averaging 6.0 points (47.1% FG, 75.6% FT) and 5.4 rebounds in 18.3 minutes. He anchored the Celtics league-leading defense, which allowed just 97.6 points per 100 possessions with him on the court (3rd best among players who played in half of their team’s games).

“Aron was a big part of our success this past year and we’re thrilled to have him back,” said Celtics President of Basketball Operations Danny Ainge. “He’s a great teammate and an anchor to our defense. The energy and passion that he brings to the table are contagious.”

The Australian native capped off last season with a career-high 26-point (12-23 FG), 14-rebound performance against Brooklyn on April 11, making him the first Celtics center to produce 25+ points and 14+ rebounds in a single game since Kevin Garnett (12/3/08).

Baynes played in all 19 of Boston’s postseason games in 2018 (12 starts), averaging 6.0 points (50.6 FG, 72.2% FT) and 6.2 rebounds in 20.5 minutes. He also shot a team-best 11-for-23 from beyond the arc (47.8% 3-PT) throughout the NBA Playoffs.

A six-year NBA veteran, Baynes has averaged 5.4 points (50.2% FG, 80.2% FT), 4.4 rebounds and 15.0 minutes in 376 career games (91 starts) with San Antonio, Detroit and Boston.
