This stash pick is no trash pick. The Knicks may not have a center on their roster yet for this season, but feel they have a potential pivot for their rotation in 2016-17 – 6-foot-11 Spanish League second-rounder Guillermo Hernangomez.

The Sixers had five second-round picks and traded their 35th selection to the Knicks Thursday for their 2020 and 2021 second-rounders plus cash. According to a source, the Sixers already had a deal in place with the Knicks at No. 35 when they picked the Spaniard, who had already informed the Sixers he wasn’t interested in playing there.

The Knicks were more than interested in the stash pick who is known as a solid rebounder, giving first-rounder Kristaps Porzingis a friend and former teammate. When general manager Steve Mills watched a game in Spain to scout Porzingis play for Sevilla, he noticed his teammate could serve as a legitimate big man in the NBA, too.

“[Hernangomez is] a blue collar player,” said Knicks former European scout Tim Shea, who lives in Spain and works as a coaching mentor. “Plays hard. He’s still developing — at the moment makes his presence felt inside more by density than athleticism. But he knows how to get position and plays defense with passion. He rebounds more by position and boxing out and isn’t a ‘wow’ athlete. But he has good footwork inside on offense. He’ll be a solid contributor in a couple of years.”

Hernangomez’s buyout is too hefty so he will stay one more season. Porzingis said they communicate often and was excited to hear of the selection.
