Just in case the Warriors needed more winning chemistry, they added someone Tuesday with future family ties to Stephen Curry.

Golden State agreed to a deal with free-agent guard Damion Lee, the fiancé of Curry’s younger sister, Sydel. The 25-year-old Louisville product is expected to sign a two-way contract with the back-to-back NBA champions, ESPN first reported.

Lee, whose only NBA experience came in 15 games with the Hawks last season, appeared to get engaged to Sydel Curry last November, with the two sharing the news on their Instagram accounts the same day.

“Thank you Jesus for this man. Thank you for your perfect timing,” Curry captioned a photo of her, Lee and her new ring. “Tonight I said yes to the man of my dreams and I couldn’t be more happy. I love you Damion Lee and cant wait to be your wife. Holy crap!!!”

Lee, known for his scoring ability, should fit right in with the offensive-minded Warriors. The 6-foot-6 shooting guard averaged 10.7 points on 40.8 percent shooting with the Hawks. He spent the majority of the 2017-18 season playing for the Warriors’ Santa Cruz G-League affiliate.

Lee went undrafted in 2016 after transferring from Drexel to Louisville for his redshirt senior season and leading the Cardinals in scoring with 15.9 points per game.

The Warriors made early headlines in free agency, signing center DeMarcus Cousins, a four-time All Star, to a one-year, $5.3 million deal on July 2 and putting an explanation point on their superteam for next season.
