ATLANTA — The Atlanta Hawks have officially re-signed All-Star Paul Millsap and finalized a trade for reserve center-forward Tiago Splitter.

Millsap, a two-time Eastern Conference All-Star, was an unrestricted free agent before agreeing last week to a three-year, $58.9 million deal contract.

In his second year with the Hawks last season, Millsap helped the team win 60 games for the first time and reach the Eastern finals.

He led Atlanta with averages of 16.7 points, 7.8 rebounds, 1.8 steals and 15 double-doubles. Millsap hit a career-high 77 3-pointers and averaged 3.1 assists.

Coach Mike Budenholzer said re-signing Millsap was an offseason priority.

“His toughness, versatility, high basketball IQ and unselfishness (are) representative of the culture we are building,” Budenholzer said in a statement released by the team. “We are excited that he will remain a part of our family.”

The Hawks lost starting guard DeMarre Carroll to Toronto in free agency, but added Tim Hardaway Jr. in a draft-night trade with New York and acquired Splitter last week after sending the draft rights to Georgios Printezis and a future second-round pick to San Antonio.

Splitter averaged 8.3 points, 5.3 rebounds in his first five NBA seasons with the Spurs. Atlanta sent the draft rights to Georgios Printezis and a future second-round pick to acquire the 6-foot-11, 245-pound Splitter.

To make room for Splitter on the roster, the Hawks requested waivers on forward Austin Daye, who signed a multi-year contract in April.

Splitter, who’s expected to back up Millsap and center Al Horford, has two years remaining on his contract and will earn a total of $16.8 million. Splitter has started 40 of 65 career postseason games.

Millsap’s deal has a player option for a third season, giving the contract a $58.9 million value. The 30-year-old Millsap is expected to make $20 million next season.
