Knicks 85, Pacers 75
NEW YORK (AP) — Carmelo Anthony scored 28 points to help the Knicks stay alive in the Eastern Conference semifinals.
Reserves J.R. Smith and Chris Copeland each had 13 points for the Knicks, who trail 3-2 and will need a victory Saturday in Indiana to force a seventh game back here Monday. They are trying to become the ninth NBA team to overcome a 3-1 deficit to win a series.
Anthony, who didn't make a basket in the fourth quarter of either game in Indiana, made a jumper midway through the fourth quarter after Indiana closed within four points. He followed with two free throws, Raymond Felton made a layup, and the Knicks were never in jeopardy again.
Paul George had 23 points, six rebounds and six assists for the Pacers. They played without point guard George Hill because of a concussion and committed 19 turnovers.
The winner will face defending NBA champion Miami in a series that will start Wednesday.
