The Knicks’ Kristaps Porzingis finished second in the NBA Rookie of the Year voting behind Minnesota’s Karl-Anthony Towns, who won the award unanimously.

The league announced the award on Monday.

Towns received all 130 first-place votes from the media and became the fifth rookie to be selected unanimously since 1984. The 7-footer joined Damian Lillard (2012-13), Blake Griffin (2010-11), David Robinson (1989-90) and Ralph Sampson (1983-84).

The top overall pick last year, Towns led all rookies with averages of 18.3 points and 10.5 rebounds, and his 1.68 blocks were second to Porzingis. Towns was eighth in the NBA in rebounding and field-goal percentage (.542) and his 51 double-doubles ranked third. He won all six Western Conference rookie of the month awards during the season.

Towns was the first rookie since future Hall of Famer Tim Duncan to average at least 18 points, 10 rebounds, 1.5 blocks and shoot 50 percent from the field

Minnesota’s Andrew Wiggins was voted top rookie last year, making the Timberwolves the first team with back-to-back winners in 42 years.
