ATLANTA — George Hill and David West each scored 21 points and the Indiana Pacers withstood a furious Atlanta comeback in the fourth quarter, beating the Hawks 81-73 on Friday night to close out the opening-round playoff series four games to two. The home team had won every game until the Hawks returned to Philips Arena and set a franchise record with just nine points in the second quarter on 1-of-15 shooting. The defense broke down in the third, allowing Hill and West to combine for 22 points, and the Pacers built a 65-50 lead going to the fourth.
