David Lee had 18 points and Robinson 15 for the Knicks, who picked up in the first half where they left off two nights ago. After scoring 72 points in the second half of their 132-103 victory in Memphis on Wednesday night, the Knicks hung 68 on the hapless Thunder in the first 24 minutes.
The Knicks (6-3) are off to their best start since also going 6-3 to open the lockout-delayed 1998-99 season, when they made their last NBA finals appearance.
This team won't go that far, but they look much better when last season, when they went under 23-59 under Isiah Thomas. New York improved to 3-1 against the Western Conference after going just 3-27 in 2007-08.
Kevin Durant returned from a one-game absence with an ankle injury to score 23 points for the Thunder, who dropped their sixth straight and fell to 1-8. Russell Westbrook, the No. 4 pick in the draft, had a season-high 19 points to go with 10 rebounds and six assists.
The Knicks scored the final nine points of the first quarter, building a 37-20 lead. They opened the second with seven in a row, opening a 44-20 bulge on Robinson's 3-pointer a little more than a minute into the period.
Robinson finally missed when a 3-pointer spun out a couple of minutes later, but by then Randolph was heating up. He scored 15 points in the quarter, and the Knicks took a 68-44 lead into the half.
The Knicks, on the wrong end of so many beatings in recent seasons, seemed to particularly enjoy the other side, cheering and laughing through the end of a young girl's singing performance during a halftime talent show.
But the break slowed them down, as Oklahoma City trimmed it to 93-77 after three behind eight third-quarter points from Durant.
The Thunder scored six straight to cut it to 100-89, and finally got to 102-95 on Westbrook's bucket with 5:13 left. Crawford scored the next four points, Randolph made two free throws, and each added another bucket to make it 112-100.
Notes: Johnny Newman holds the Knicks' record for consecutive made field goals, hitting 19 in a row from Jan. 1-8, 1988. ... Knicks rookie Danilo Gallinari received another cortisone shot for his ailing back Thursday and will have an "extended period of rest" while seeking additional opinions on treatment. Gallinari, the No. 6 pick in the draft, said he could miss six weeks.
