Porziņģis was the second scorer for the Knicks behind Derrick Williams who got 24 points. Porziņģis got five rebounds and one assist.
He looked nervous early on with the way he mishandled a few passes into the post.
But overall, coach Derek Fisher liked Porzingis' versatility and aggression on offense to get to the foul line.
''The most important thing is that we got the win,'' Porzingis said. ''I tried to play hard and help the team every way possible.''
The Knicks pulled away with a 15-0 run between the first and second quarters. The lead didn't drop below double digits over the game's final 30 minutes.
"Thank you everyone in Latvia who didn't sleep to see my debut. And thanks to the Latvians in Milwaukee who came to see my game," he tweeted.
